Hernias
  • One of the few parts of final MB where surface
    anatomy is crucial! Inguinal surface anatomy is
    used to distinguish inguinal hernias into direct
    and indirect, and to demonstrate femoral hernias.
  • Most likely to get inguinal hernias, incisional
    hernias, femoral hernias, para-umbilical hernias
    and epigastric hernias.

8
Inguinal surface anatomy
  • A Inferior epigastric artery
  • B Femoral nerve
  • C Femoral artery
  • D Femoral vein
  • E is the most important
  • THE PUBIC TUBERCLE

9
Examination of the groin
  • Usually means either a hernia, a testicular
    swelling or lymph nodes.
  • Groin Hernias
  • Either an inguinal lump or a scrotal lump you
    cant get above. If not clinically obvious, as
    the patient to stand and/or cough.
  • Femoral hernias do not usually enter the scrotum.
  • Try to gently reduce it.
  • Surface anatomy If it is below and lateral to
    the pubic tubercle its a femoral hernia. If its
    superior or medial to the pubic tubercle its an
    inguinal hernia. Inguinal is commoner.
  • Occlusion at the mid-inguinal point (i.e. halfway
    between the pubic tubercle and the anterior
    superior iliac spine, i.e. the deep ring)
    prevents an INDIRECT inguinal hernia from popping
    out. In the middle-aged male, direct is commoner.

10
Other hernias
  • Incisional 10 of hernias. Either reduceable or
    not.
  • Para-umbilical True umbilical hernias are rare
    after childhood. Para-umbilical hernias are found
    in fat middle-aged women. Repaired using Mayo
    repair
  • Epigastric hernias Fit young men
  • Frequent questions
  • What is a hernia?
  • What are the three commonest hernias?
  • Who gets most inguinal hernias? Why?
  • What is the commonest female hernia?
  • What are the complications of hernias?
  • What hernias occur ouside the abdomen?
  • What is a Richters hernia?

11
Scrotal swellings (i)
  • CAN I GET ABOVE IT? If you can then its coming
    from the scrotal structures.
  • Common Hydrocoeles, Epididymal cysts,
    spematocoeles.
  • Uncommon Tumours
  • Examine as for any lump or bump
  • The 3 Ss Site, Size, Shape
  • The 3 Cs Colour, Contour, Consistency
  • The 3 Ts Tenderness, Tethering,
    Transillumination
  • The Fer Fluctulence.

12
Scrotal swellings (ii)
  • Hydrocoeles Surround the testis and make it
    difficult to feel. Transilluminate!!!
  • Spermatocoeles and epididymal cysts Smaller, and
    arise from adnexal structures. Do not obscure
    testis usually.
  • Tumours Stony hard. Arise from testis.
  • Frequent questions
  • What investigation is appropriate for a newly
    diagnosed hydrocoele?
  • What is a hydrocoele?
  • What are the risk factors for testicular cancer?
  • What blood tests would you consider for testicle
    carcinoma?
  • What are the common types of testicle cancer and
    how are they treated?

13
Stomas (i)
  • Most likely to be either an iliostomy or an
    end-colostomy.
  • Less frequently, loop colostomy or ileal
    conduit(urinary diversion)
  • An iliostomy is in the RIF, and protrudes from
    the abdominal wall. Most commonly fashioned
    following pan-proctocolectomy in ulcerative
    colitis, or less frequently for caecal
    obstruction, polyposis coli or severe Crohns
    colitis.
  • An end colostomy is most frequently formed in the
    LIF, and sits flush with the abdominal wall. Most
    commonly formed after a Hartmanns procedure or
    some rectal excisions.

14
Stomas (ii)
  • Loop colostomies are uncommon, and tend to be
    formed in the epigastrium from the transverse
    colon, or the LIF from the sigmoid colon. It is
    usually a palliative procedure for carcinomatous
    obstruction.
  • Ileal conduit urinary diversions look just like
    ileostomies, but the bag will contain urine, even
    if only a little. They are usually formed when
    the patient has had a cystectomy, often for
    carcinoma of the bladder.
  • Frequent questions
  • What is this?
  • Why is it there?

15
Stomas (iii)
  • Complications
  • ILIOSTOMY
  • Metabolic High output, B12 and Folate deficieny,
    Stones, Anaemia.
  • Anatomical Stoma Prolapse and retraction, less
    frequently stomal stenosis or parastomal
    herniation
  • COLOSTOMY
  • Mostly Anatomical
  • EARLY Stomal necrosis, ischaemia
  • LATE Stomal retraction, prolapse, stenosis,
    parastomal herniation etc

16
Small bowel obstruction
  • Intestinal obstruction is characterised by
    vomiting, abdominal distension, constipation and
    pain.
  • In high obstruction, the vomiting tends to occur
    earlier then the constipation. The reverse is the
    case for lower GI obstruction. In high
    obstruction, the distension is minimal.
  • The commonest causes are Adhesions (60-80 of
    cases) and Hernias (10-15).
  • Others include
  • Extrinsic Volvulus, Non-GI neoplastic or
    inflammatory masses
  • In the wall Crohns disease, Intussussception,
    Strictures, Atresias.
  • In the Lumen Meconium ileus, Gallstones, Foreign
    body, Faecolith.

17
Small bowel obstruction
  • Treatment
  • Assess for strangulation (Localised tenderness
    pain)
  • If simple (ie no strangulation)
  • IV fluids, NBM, Analgesia
  • FBP, UE
  • Monitor urine output
  • NG aspiration for vomiting, if required.
  • Remember, the rule is that 80 of simple small
    bowel obstruction will settle with conservative
    treatment.

18
Large Bowel obstruction
  • Causes
  • Colonic Carcinoma (65)
  • Diverticular disease (10)
  • Volvulus (5)
  • Crohns disease
  • Hernia
  • Strictures Ischaemic, anastamotic, inflammatory
    etc

19
Abdominal Masses
  • Non-pathological Gravid Uterus, Faeces in colon,
    Riedels lobe of liver, kidneys in a thin person.
  • Standard questiion is to distinguish a kidney
    from a spleen
  • RIF
  • Sore Appendix mass/abscess, Crohns mass
  • Not Sore Cancer (Caecal, Ovarian, Renal),
    Fibroids and ovarian cysts, transplanted kidney.
  • Epigastric
  • Ca stomach, colon, liver, pancreas
  • RUQ
  • Liver, Colon, Right kidney, GB, Adrenal

20
Colorectal Disorders
  • Colorectal Carcinoma
  • Important point is that the history is different
    depending on the side of the colon the carcinoma
    is
  • RIGHT sided carcinomas Present insidiously
    because the colonic contents are liquid and the
    colon relatively spacious at this point.
    Presentation is with the development of anaemia
    Fatigue, malaise, weight loss, dark blood in
    stools.
  • LEFT sided carcinomas present with the symptoms
    of narrowing the lumen to more solid matter,
    Altered bowel habit, alternating constipation and
    diarrhoea, brighter red PR bleeding.
  • RECTAL carcinomas also have the symptoms of
    tenesmus and passage of mucus PR
  • Colonic carcinomas can also perforate and
    fistulate

21
Colorectal Disorders
  • Risk Factors
  • Longstanding Ulcerative colitis
  • Polyposis Coli
  • Family History
  • Differential diagnosis
  • DIVERTICULAR DISEASE
  • Any cause of large bowel obstruction
  • PR Bleeding Colorectal CA, Diverticular disease,
    Angiodysplasia, Haemorrhoids, Anal fissure
  • Investigations of choice Barium enema and
    sigmoidoscopy, with CT if carcinoma is confirmed.

22
Colorectal Disorders
  • TREATMENT
  • Surgery
  • Chemotherapy with 5-Fluorouracil for tumours of
    stage Dukes C or greater. Some would also give it
    for Dukes B
  • Colorectal Carcinoma Complications Bleeding,
    Perforation and Fistulation into adjacent organs
    and obstruction

23

24
Colorectal Disorders
  • DIVERTICULAR DISEASE
  • The great pretender. Can mimic colorectal
    carcinoma remarkably. Both cause PR bleeding, can
    cause intestinal obstruction, can perforate and
    can fistulate.
  • Related to low-fibre diet
  • Chronic symptoms investigated with Ba enema and
    Sigmoidoscopy. (Arent they all)
  • Often presents acutely with LIF pain and
    tenderness and rebound. Settles with conservative
    Rx and Antibiotics usually.
  • Majority do not require surgery, and are
    controlled with dietary advice

25
Colorectal Disorders
  • Inflammatory Bowel disease Summary table

26
Colorectal Disorders
  • Ulcerative colitis
  • Palpable masses rare, never fistulates
  • Anorectal fissures and infection occur less
    frequently
  • Medical Rx successful in 80
  • Surgery can be curative
  • Crohns Disease
  • Occasionally forms inflammatory masses or
    fistulae
  • Anorectal sepsis common
  • Medical Rx inadequate in 80
  • Surgery for complications only

27
Colorectal Disorders
  • Medical treatment of ulcerative colitis
  • 5-ASA derivatives, such as Sulphasalazine or
    Mesalazine can be used to reduce relapse rate.
    Delivered either orally, Enemas or suppository
    form
  • Prednisolone can be used topically as above, or
    can be given orally for relapses, up to 60mg per
    day. It must be weaned off, rather than stopped
    suddenly.
  • Anti-diarrhoeals Codeine, Loperamide.
  • Endoscopy is used for surveillance
  • Surgery is used for failure of medical Rx, For
    Carcinoma, Failure of steroids to induce response
    in few days, and Toxicity gt8 bloody stools per
    day, pulse gt100, Temp gt 38.5 C, Transverse colon
    dilated beyond 5cm and hypoalbuminaemia.
  • Often a panproctocolectomy and iliostomy

28
Colorectal Disorders
  • Crohns disease
  • Usually not accessable by topical preparations,
    so generally treated with systemic 5-ASA
    derivatives or steroids where flare up occurs.
  • Surgery is often used for the complications
    Abscess drainage, resection of fistulas, and
    removal of strictured segments.
  • Cannot be cured by surgery. Colonic crohns is a
    contraindication for continent pouch procedures.

32
Oesophagus and Stomach
  • More likely to be used in the long case setting,
    as signs are uncommon, but history is usually
    detailed.
  • Haematemesis and melaena.
  • Use of NSAIDS eg Aspirin, Smoking, Alcohol,
    Steroids, WARFARIN
  • Remember to say PR

33
Stomach and Oes. History (i)
  • This is actually the history of upper GI
    bleeding, Upper abdominal pain, and upper GI
    obstruction, with history.
  • Upper GI Bleeding
  • Was it haematemesis or melaena
  • Did one start before the other
  • When did it start
  • How many times has it happened
  • When did it happen last
  • Was it precipitated by anything
  • How much blood was there
  • Coffee-grounds vs fresh blood
  • Did it make them collapse
  • Have they felt tired / easily fatigued / easily
    short of breath ANAEMIA!

34
Stomach and Oes. History (ii)
  • Upper GI obstruction Oesophagus or Gastric?
  • At the level of the Oesopagus Dysphagia,
    regurgitation of food
  • At the level of the Stomach Early satiety,
    Forceful vomiting, Sucussion splash if youre
    lucky!
  • Both give marked weight loss
  • History
  • Drug history NSAIDS Aspirin, Warfarin,
    Steroids.
  • Smoking Amount per day, and duration. Have you
    ever smoked?
  • Alcohol As for smoking.
  • Family history
  • Upper GI pain and differential later

35
Stomach and Oesophagus signs
  • Signs THINK Bleeding, Baccy and Booze.
  • Bleeding Pale conjunctivae, pallor. Melaena. (ie
    more chronic signs) Unlikely to see tachycardia,
    hypotension etc, as this tends to be quite acute.
    Remember NSAIDS and Warfarin. Trap for the
    unwary Guinness or Iron tablets give you black
    stools.
  • Smoking The most obvious is often nicotine
    stained fingers! Also remember the signs of COAD
    It implies a smoking history. Smoking also
    significant in the context of cancer Look for
    wasting, an LIF mass, Hepatomegaly etc.
  • Alcohol This essentially means the signs of
    chronic liver disease.

36
Stomach and Oesophagus
  • Oral Questions relating to haematemesis /
    melaena
  • What risk factors did this patient have for Upper
    GI bleeding?
  • Why are they on Aspirin / Warfarin / Steroids ?
  • What investigations will you do AND WHY?
  • FBP, Coag, UE, LFT, GCsm 4 units, OGD.
  • If the OGD is negative what investigation will
    you do (Melaena)?
  • BARIUM ENEMA
  • What are the commonest causes of upper GI
    bleeding
  • Gastritis, Duodenitis

37
Stomach and Oesophagus
  • What are the causes of upper GI bleeding
  • Oesophagus Oesophagitis, Oesophageal erosions,
    Mallory-Weiss tears, Oesphageal varices,
    Oesophageal carcinoma (rarely)
  • Stomach Gastritis, Gastric erosions, Gastric
    ulcers, Gastric carcinoma.
  • Duodenum Duodenitis, Duodenal Ulcers,
    Aorto-Enteric fistulas.
  • How do you treat upper GI bleeding?
  • Most settle with conservative Rx IV fluids, NBM,
    PPI. Can use endoscopy therapeutically for both
    ulcers and varices. Open resection of ulcer etc
    rare.
  • What are oesophageal varices?
  • What causes them?
  • What are the other sites of porto-systemic
    anastamosis?

38
Stomach and Oesophagus
  • Difficult Question
  • How would you see this?
  • What is it?

39
Stomach and Oesophagus
  • This is a barium swallow.
  • What is the likely diagnosis?
  • Difficult question.

40
Stomach and Oesophagus
  • How would you investigate the patient with a
    tumour of the stomach or oesophagus on OGD ?
  • Stage them, using a CT scan of Chest, Abdomen and
    Pelvis. If resectable then treat surgeically if
    possible. Radiotherapy is second-line option for
    oesophagus. Many Gastric and oesophageal tumours
    are irresectable, so remember to consider
    palliative care options such as bypass and
    stenting, laser resection of oesophagus.
  • What is Barretts Oesophagus?
  • What is its significance?
  • How do you manage it?
  • What might cause dysphagia?
  • What drugs are associated with upper GI bleeding?

41
  • What kind of X-ray is this?
  • What does it show?

42
The Liver, biliary system and pancreas
  • History features
  • Jaundice, Upper abdominal pain.
  • Jaundice The A to I varies from book to book,
    but I use
  • Alcohol
  • Blood tranfusion
  • Contact
  • Drugs (eg Paracetamol)
  • Extrahepatic
  • Family History, Foreign Travel
  • Gallstones
  • Homosexuality
  • Infections ( HBV, EBV, Leptospirosis)

43
The Liver, biliary system and pancreas
  • Upper Abdominal pain
  • Epigastric
  • Upper GI Gastritis, Oesophageal reflux, Peptic
    Ulcer, Perforation of gastric or duodenal ulcer.
  • Hepatobiliary Biliary Colic, Pancreatitis
  • REMEMBER MYOCARDIAL INFARCTION
  • Right Hypochondrium
  • Hepatobiliary Biliary Colic, Cholecystitis,
    Cholangitis, Hepatitis, Pancreatitis,
    Fitz-Hugh-Curtis syndrome.
  • Upper GI Peptic Ulcer, Perforation of Ulcer
  • Other Abdominal Subphrenic abscess,
    Appendixitis, Renal Colic
  • Extra-Abdominal Right lower lobe pneumonia,
    Pulmonary embolus.

44
The Liver, biliary system and pancreas
  • Physical examination often involves looking for
    the signs of chronic liver disease in the case of
    jaundice or pancreatitis. Cholecystitis is most
    frequently abdominal signs only, if
    un-complicated.
  • Surgeons most frequently look after Cholecystitis
    and Pancreatitis.
  • Cholecystitis Remember the 5 Fs! It gives the
    game away.
  • Right Upper quadrant pain, aching/colicky, may
    radiate around to back, often onset at night or
    in response to fatty foods, may be associated
    with vomiting. Gallstones in the gallbladder do
    not cause jaundice unless they move into the
    common bile duct.
  • Complications Jaundice, Pancreatitis.

45
The Liver, biliary system and pancreas
  • Physical examination usually only shows subcostal
    tenderness and murphys sign. Rarely palpable. 5
    Fs
  • The investigation of cholecystitis is essentially
    the investigation of upper abdominal pain.
  • FBP, UE, AMYLASE, LFTs, Erect Chest X-Ray,
    Abdominal film.
  • Initial Rx IV Fluids, Nil by mouth.
  • Cefuroxime for infection. Most add Metronidazole
    as well. Cholangitis is Jaundice, Fever and
    Rigors. This is known as Charcots triad.
  • Investigation Ultrasound of abdomen. OGD if its
    normal.
  • Treatment Laparoscopic cholecystectomy or open
    cholecystectomy. (Dont use laparoscopic surgery
    if there are adhesions, or a common bile duct
    stone)

46
The Liver, biliary system and pancreas
  • Stones in the common bile duct may produce
    jaundice and pancreatitis. They are suspected
    when ultrasound detects a dilated common bile
    duct, or visualised duct stones.
  • An ERCP can the be carried out to prove the fact,
    and the sphincter of oddi divided to allow the
    stones to pass harmlessly into the duodenum.
  • They are not removed by a laparoscopic
    cholecystectomy. At the time of open surgery, an
    intraoperative cholangiogram is performed to
    ensure that none are present. If there are, then
    they are removed with specialised forceps.

47
The Liver, biliary system and pancreas
  • Pancreatitis
  • Presentation is similar to Cholecystitis, but
    pain is more centralised and is more severe,
    possibly radiating to the back. Classically the
    patient lies still with their knees bent. They
    are generally more unwell. May be shocked,
    jaundiced.
  • Physical signs are often absent or very scanty!
    Consider the signs of chronic liver disease,
    Cullens sign and Gray-Turners sign. Abdominal
    tenderness to palpation can be poorly localised
    and hard to define. Pyrexia, Tachycardia.
  • Initial investigations are the same as for
    cholecystitis FBP, UE, LFT, Amylase, CXR, AXR.
    Amylase is considered diagnostic for pancreatitis
    if it is greater than 1000 u/ml. Abdo Xray may
    show a sentinel loop or loss of psoas shadow.

48
The Liver, biliary system and pancreas
  • Causes Gallstones and Alcohol most common. Also
    GET SMASHD Trauma and Surgery, Steroids, Mumps,
    AI, Scorpions, Hyperlipidaemia and drugs.
  • Treatment
  • Once diagnosis is established do an arterial
    blood gas and a serum calcium glucose. Treat
    any hypocalcaemia.
  • IV fliuds, nil by mouth. Aim to keep urine output
    above 30 mls per hour. Consider central line in
    elderly or CCF patients.
  • Opiate analgesia
  • NG tube
  • Monitor
  • Hourly urometer, Pulse and BP
  • 12-hourly arterial bolld gases
  • Daily FBP, UE, Calcium and amylase

49
The Liver, biliary system and pancreasYou must
learn the Ranson criteria, as it is a measure of
severity. 0-2 2 motality, rising to 100 for 7

  • Fluid sequesteredgt 6 litres

50
Jaundice
  • Most surgeons look after post-hepatic jaundice.
    This type of jaundice is charcterised by dark
    urine and pale stools. This is because bilirubin
    products are not allowed to pass into the GI
    tract via the biliary tree, but conjugated
    bilirubin is water soluble and so darkens the
    urine.
  • Jaundice is divided into pre-hepatic, hepatic and
    post-hepatic aetiologies.
  • Pre-Hepatic Haemolysis, Heriditary eg Gilberts
  • Hepatic Cirrhosis, Carcinoma infiltration,
    Viral, Autoimmune, Paracetamol and other drugs.
    Halothane is no longer used.
  • Post-Hepatic (Obstructive) CBD gallstones,
    Pancreatic carcinoma, Nodes in the porta-Hepatis,
    Cholangiocarcinoma. Complication of lap chole?

51
Jaundice
  • The physical signs of chronic liver disease is a
    gob-standard exam question. Remember to start at
    the hands and work up!
  • Hands Finger clubbing, Leukonechia, Palmar
    erythema, Dupuytrens, Asterixis
  • Skin Bruising, Spider Naevi, hair loss
  • Face Head Jaundiced sclera. Constructional
    apraxia, Foetor hepaticus.
  • Chest Gynaecomastia
  • Abdomen Enlarged liver or spleen, Ascites, Caput
    Medusae. Remember to ascertain the nature of the
    liver edge, consistency, tenderness. Bruits etc
    astronomically rare.
  • Legs Peripheral pitting oedema from
    hypoalbuminaemia.

52
Jaundice
  • Investigation of the jaundiced patient
  • FBP, UE, LFT, Coagulation, Hepatitis
  • Remember Macrocytosis as a sign of alcoholism
  • In obstructive jaundice, the Alkaline Phosphatase
    will rise out of proportion to the transaminases
    (These may be slightly up), and the bilirubin is
    conjugated.
  • Hepatocellular jaundice is characterised by
    marked transaminase rise, and a mix of conjugated
    and unconjugated bilirubin.
  • Prehepatic Jaundice is unconjugated, (so not
    present in urine)
  • Ultrasound This will tend to separate the
    Hepatic and Post-hepatic jaundices quite nicely
    also.

53
Jaundice
  • Questions
  • What are the causes of Cirrhosis?
  • Alcohol and Hepatitis are the first things to say
  • If pressed
  • Primary Biliary Cirrhosis, Autoimmune hepatitis
  • Haemochromatosis and Wilsons disease
  • Drugs eg Methotrexate
  • Budd-Chiari syndrome (Hens tooth), Cong Cardiac
    failure.
  • Alpha-1-antitrypsin deficiency
  • How would you prepare the jaundiced patient for
    surgery?
  • Basically this means correcting any coagulation
    abn with FFP and/or Vitamin K, and giving
    perioperative IV fluids to maintain a good urine
    output (Hepatorenal syndrome more likely in the
    dehydrated)

Breast lumps
  • Common Breast Lumps
  • Young Women Fibroadenoma / Abscess
  • Pregnant / recent sprog Galactocoele / abscess
  • Middle aged and elderly women Cancer higher up
    the differential diagnosis list.
  • Investigation IN THIS ORDER
  • Clinical examination
  • Mammogram (USS if premenopausal)
  • FNA aspiration

56
Breast Cancer Treatment
  • Local treatment
  • Usually lumpectomy/partial mastectomy if feasble.
    Not feasable for central tumours, large tumours
    or tumours in small breasts etc.
  • Systemic treatment
  • Premenopausal usually chemotherapy
  • Postmenopausal usually Tamoxifen. (Remember risk
    of uterine CA)

57
Vascular Cases
  • Likely Cases
  • Aneurysm (AAA)
  • Ischaemic lower limb
  • Ulcer
  • Varicose veins

58
Aneurysm
  • Mostly Aortic (Within abdo) Next most common is
    splenic artery aneurysm. Think of Elderly male
    hypertensive smokers with family history.
  • Usually need repaired if greater than 5
    centimeters in diameter (Risk of bursting
    increases above this)
  • Inv FBP, UE, ESR (?Inflammatory), CT scan,
    Chest X-ray and ECG
  • Need emergency CT if painful aneurysm has it
    burst?
  • Now can be repaired with endoluminal stenting in
    some cases.

59
Chronically Ischaemic lower limb
  • Signs
  • Absent pulses
  • Colder than other limb
  • Thin, Shiny skin
  • Hair loss on leg
  • Ulcers
  • gangrene
  • Symptoms
  • Claudication
  • At what distance.
  • How long does it take to disappear at rest
  • On the flat or just uphill
  • Rest pain?
  • Relevant PMH
  • Smoking
  • Diabetes
  • Hypertension, Stroke, MI, etc

60
Investigation
  • Ankle-Brachial pressure index
  • Take systolic BP at brachial artery using doppler
    USS, and compare it to the systolic BP at
    posterior tibial or dorsalis pedis artery.
  • Divide the ankle value by the arm value. Should
    be the same. 0.5Claudication, 0.3Rest pain,
    0.2 impending gangrenous changes.
  • Definitive main investigation is arteriography.

61
Whats this?
62
Ulcers
  • Usually
  • Venous Medial malleolus, Venous excema, varicose
    veins, skin pigmentation. Surprisingly painless!
  • Arterial Black, sloughy, painful. Look for other
    signs of limb ischaemia.
  • Neuropathic. Sensory loss. Often diabetics with
    good pulses
  • Vasculitic. Sharp, punched out lesions.

Urology in a nutshell
68
Causes of Haematuria
  • PRE-RENAL Coagulation disorder, Sickle-cell,
    Vasculitis
  • RENAL Glomerular disease, Carcinoma, Cystic
    disease, Trauma, A-V malformations,
    Emboli
  • POST RENAL Stones
  • Infection (Bladder / Prostate / Urethra)
    Carcinoma (Bladder / Prostate),
    Traumatic bladder catheterisation,
    Inflammatory Cystitis

69
Investigation of Haematuria
  • Painless haematuria is carcinoma until proven
    otherwise
  • Initial investigation (For Anything) is full
    history and examination.
  • PR!

70
Investigation of Haematuria
  • Blood Investigations
  • FBP Anaemic? White cell count raise indicative
    of infection?, Enough platelets?
  • UE Are their kidneys working? (Crude test)
  • Coagulation screen Haemophilia?, Warfarin?
  • In Men PSA
  • REMEMBER MSSU Direct microscopy and culture.

71
More Investigation
  • Urinary Cytology
  • Not very sensitive, but an unequivocally
    positive cytology is quite specific for TCC
    bladder.
  • RADIOLOGY
  • IVP
  • Ultrasound
  • Both are very sensitive and specific, but USS
    better for small peripheral renal lesions, and
    IVP better for renal pelvis and ureters.
  • FLEXIBLE CYSTOSCOPY

72
Bladder Cancer Incidence
  • Males outnumber females by about 2.7 to 1
  • Average age at diagnosis is 65 years.
  • 85 confined to bladder at time of presentation.
  • 70 will recur after treatment, and 30 of these
    will progress
  • Risk Factors
  • SMOKING
  • Chemical carcinogens chemical, dye, rubber,
    petrol, leather and printing industries are at
    increased risk. Also Cyclophosphamide
  • Not Coffee

73
Initial diagnosis and treatment
  • Most are diagnosed using flexible cystoscopy
    under fresh air, and haematuria investigations.
  • Non-invasive tests such as PCR analysis, and
    Matrix-metalloproteinase-9 are yielding some
    results with high specificity and sensitivity,
    but remain research tools at present.
  • IVP Make sure there are no TCC in the renal
    pelvis or ureters. For every 50-60 bladder
    carcinomata, there are 3 Renal pelvis TCCs and
    one ureteric TCC
  • TURBT Curative for early disease, also provides
    histology.

74
Staging of TCC bladder
CIS Ta T1 T2 T3a
T3b
mucosa sub-mucosa detrusor muscle Peri-vesical
fat
75
Staging Continued
  • Also Stage T4a, where the prostate is invaded,
    and T4b where there is pelvic structure invasion.
    T3b has a worse prognosis than T3a.
  • Lymph nodes status, and presence or absence of
    metastases.
  • Tumour Grade i.e. degree of preservation of
    cellular architecture, mitotic figure number etc.
  • Why bother staging? Treatment is tailored to
    stage of disease

76
Treatment Options
  • Ta Single, G1-2, Not recurrent TURB
  • Multiple, recurrent, or high grade TURBIntrave
    sical chemo
  • T1 G1-2 TURBIntravesical chemo
  • G3 TURBBCG
  • CIS TURBBCG
  • T2-T4 Radical Cystectomy
  • Radiotherapy
  • N or M ?Chemotherapy - MVAC

77
Surgery and Radiotherapy
  • TURBT
  • Radical cystectomy Major intra-abdominal
    procedure. Can divert urine either to an ileal
    conduit, or make a new bladder from bowel or
    colon. Incidental lymph node mets found in 20-35
    5 year survival a bit better than DXT 65 for
    T2-T4 disease.
  • Pelvic Radiotherapy 20-40 5 year survival, but
    15 get local complications, e.g. radiation
    cystitis or proctitis.

78
Chemotherapy
  • Intravesical
  • Mitomycin response rate 40-50. Consider single
    dose intravesically post surgery rather than 6
    week course. Occasionally produces chemical
    cystitis.
  • BCG decreases recurrence from 80 to 40, and
    decreases progression from 35 to 7. Cystitis in
    90 and haematuria in 33
  • Systemic
  • MVAC (Methotrexate, Vinblastine, doxorubicin,
    cisplatin) 13-35 response rate, but median
    survival rate is only one year
  • Difficult to convince oncologists to give!

79
The bottom line
  • Five-year survival
  • Stage
  • Ta 94
  • T1 69
  • T2 40
  • T3 31
  • T4 0
  • Worse with increasing grade, and increased grade
    and stage associated with increased risk of
    metastatic disease.

80
Why Is a Spleen Not a Kidney?
  • Very common exam question!
  • Kidneys do not move with respiration
  • Kidneys enlarge up down, not to the RIF
  • Kidneys are resonant to percussion
  • Kidneys are ballottable
  • Kidneys do not have a notch
  • You can get above a kidney

81
What Causes Big Kidneys?
  • Unilateral
  • Carcinoma
  • Renal cell, transitional cell in adults
  • Nephroblastoma (wilms tumour) in kids
  • Hydronephrosis
  • Tend to be chronic e.g. PUJ obstruction, reflux
  • Simple cysts
  • Compensatory hypertrophy
  • Bilateral
  • Polycystic kidneys
  • Bilateral hydronephrosis
  • Amyloid hens tooth

82
Renal Cell Carcinoma
  • Synonyms hypernephroma, clear-cell carcinoma.
  • Incidence 2-3 of all adult cancers.
  • Renal cell carcinoma is roughly 85 of all renal
    tumours, the remainder being things like
    transitional cell carcinoma of the renal pelvis,
    and renal sarcoma.
  • Age peak of 40-70 years old.
  • Males outnumber females 21
  • Risk factors
  • Smoking.
  • Others Von-Hippel Lindau syndrome, horseshoe
    kidneys, adult polycystic kidney disease,
    acquired renal cystic disease.

83
RCC Aetiology and Presentation
  • Arises from the cells of the proximal convoluted
    tubule.
  • Presentation classically
  • Haematuria
  • Flank pain
  • Loin mass
  • 50 diagnosed as incidental findings in 1995,
    during USS or CT for other problem.
  • 30 present with metastatic symptoms
  • Bone pain, dyspnoea, cough, etc.
  • (Often to liver, lungs, bones, brain and adrenal
    glands)

Only true in 15
84
Why Physicians Like It
  • Paraneoplastic syndromes
  • Erythrocytosis (3-10) from increased
    erythropoetin production.
  • Hypercalcaemia (3-13) either from a PTH-like
    substance, or from osteolytic hypercalcaemia.
  • Hypertension (Up to 40)
  • Deranged LFTs Stauffers syndrome, from
    hepatotoxic tumour products.
  • Sundry others Rarely produces ACTH (Cushings
    syndrome), enteroglucagon (protein
    enteropathy), prolactin (galactorrhoea),
    insulin (hypoglycaemia) and
    gonadotropins.

85
Diagnosis and Staging
  • Initial diagnosis
  • FBP, UE, LFT.
  • IVP and ultrasound.
  • MSSU direct microscopy.
  • Staging
  • CT scan chest, abdomen and pelvis /- head.
  • Isotope bone scan.
  • Rarely
  • Renal arteriography.
  • Biopsy.
  • Cavogram.

86
Pathological Staging (1)
  • May be different than your textbooks. The TNM
    people revised this in 1997, and it may not be in
    older versions.
  • Tumour
  • T1 lt7cm, intra renal
  • T2 gt7 cm, intra renal
  • T3 tumour extends into major veins or perinephric
    tissues, but not beyond gerotas fascia
  • T4 tumour beyond gerotas fascia
  • Lymph nodes
  • N0 no nodes
  • N1 single lymph-node lt 2cm
  • N2 single lymph node 2-5cm or multiple nodes lt5cm
  • N3 any nodes gt5cm
  • Metastases
  • M0 no metastases
  • M1 distant metastases (often to liver, lungs,
    bones, brain and adrenal glands)

87
Pathological Staging (2)
  • And after all that
  • Stage 1 T1 N0 M0
  • Stage 2 T2 N0 M0
  • Stage 3 T1-2 N1 M0
  • T3 n0-1 m0
  • Stage 4 T4 any N M0
  • Any T N2-3 M0
  • Any T any N M1

88
Treatment
  • Get rid of the primary tumour
  • Radical nephrectomy
  • Open or laparoscopic? Laparoscopic has faster
    patient recovery, but is time-consuming in
    theatre.
  • Partial nephrectomy for small polar tumours, less
    than 4 cm diameter.
  • Embolisation.
  • Consider small tumours below 2cm in unfit
    patients for watching?

89
Chemotherapy?
  • Renal cell carcinoma has a track record of being
    unresponsive to chemotherapy.
  • Immunotherapy
  • Only works for clear cell type, the largest
    pathological group of RCC.
  • Only used if lymph-node metastases, or metastases
    to solid organs. Cerebral metastases are a
    contra-indication.
  • Combination regimens based on cytokines
  • Interleukin-2 19 response rate alone
  • Interferon-a 11 response rate
  • Together 25-30 response
  • Combinations of interleukin-2, interferon-a and
    5-fluorouracil have produced response rates of
    39 in one series.
  • The main problem with immunotherapy is that it
    has a lot of side effects, such as fever,
    hypotension, tachycardia, oliguria. You can end
    up in ICU from it, but this is rare.

90
The Bottom Line
  • Responses to immunotherapy tend to be
    short-lived, i.e. Months.
  • Relapsers tend not to respond to more
    immunotherapy.
  • 5-year survival
  • T1 88-100
  • T2 t3a 60
  • T3b 15-20
  • T4 0-20

Tumor stage T3 can be subdivided into 2 groups
T3a can invade the adrenal or perinephric tissue,
but remains within gerotas fascia, and T3b
invades the Renal vein or IVC.
91
Other Renal Tumours (Adult) Uncommon
  • Sarcoma females outnumber males by 21. Surgery
    only effective therapy. Prognosis poor.
  • Transitional cell carcinoma of the renal pelvis.
  • Haematologic tumours (lymphoma deposits etc)
  • Metastatic tumours (In order of frequency)
  • Lung
  • Breast
  • Stomach
  • Non-tumours that masquerade as such
  • Oncocytoma
  • Angiomyolipoma
  • Others leiomyomas, haemangiomas

92
Symptoms of BOO
  • Irritative
  • Frequency, Urgency, Nocturia gt 2 times per night
  • Obstructive
  • Hesitancy, Poor flow, Terminal dribbling.
  • Others
  • Recurrent urinary tract infections as a
    consequence of impaired bladder emptying
  • Haematuria rarely.
  • Can be scored using IPSS system

93
Causes of impaired bladder emptying(i)
  • Detrusor failure, i.e. weak bladder
  • Think of the bladder with its nerve supply. Any
    disorder of nervous control may impair emptying.
    For example
  • Spine Injuries, Disc prolapse, Spina bifida.
  • Nerves Diabetes, Multiple sclerosis.
  • Bladder Myogenic failure.

94
Causes of impaired bladder emptying(ii)
  • Outlet Obstruction i.e. blocked bladder
  • Mostly a male phenomenon. Can be any cause from
    bladder neck to outside world. For example
  • Prostatic enlargement
  • Bladder neck hypertrophy (Often post TURP)
  • Urethral strictures (Often post instrumentations,
    also STD)
  • Meatal stenosis (As for strictures, also after
    botched circumcisions and a condition called
    Balanitis Xerotica Obliterans)
  • In male infants Posterior urethral valves

95
Investigation of BOO symptoms
  • History and examination
  • Dont forget to do PR!!!
  • FBP, UE, Glucose, MSSU
  • Prostate specific antigen (PSA)
  • Currently best blood-test for separating benign
    prostatic disease from prostate cancer. It rises
    in cases of cancer. It can also rise with urinary
    tract infections, and following episodes of
    urinary retention or urinary instrumentation.
    Also slowly rises with age.
  • Ultrasound of bladder (Is it emptying? If
    creatinine abnormal then also ultrasound kidneys,
    looking for obstructive uropathy)
  • Urinary flow rate

96
Benign Prostatic Hypertrophy
  • PSA should be within normal range or biopsies
    have shown no carcinoma.
  • Usually treated medically, unless there is an
    absolute indication for surgery
  • Refractory retention
  • Recurrent UTI
  • Bladder stones
  • Obstructive uropathy
  • Recurrent or persistent haematuria
  • Symptom control is only a relative indication!

97
Obstructive Uropathy
  • Basically this is renal impairment caused by
    chronic bladder outlet obstruction.
  • It produces a detectable rise in creatinine, and
    eventually can be seen on ultrasound as thinning
    of the renal cortex.
  • It means that the best treatment is operative
    relief of obstruction.

98
Acute Urinary Retention
  • This is the end-stage of urinary outflow
    obstruction.
  • Preceding outlet symptoms, with the straw that
    breaks the camels back often being an
    intercurrent UTI, an episode of constipation,
    immobility or post-operatively.
  • Provided there is no obstructive uropathy, can be
    started on medical treatment and catheter removed
    after a day or two.

99
Medical management of prostatic obstruction
  • Two broad groups of drugs
  • Alpha-blockers These produce smooth muscle
    relaxation within the prostate, and so widen the
    outflow tract. Older generation drugs have been
    associated with postural hypotension, but newer
    drugs such Tamsulosin have minimised this.
  • 5-alpha reductase inhibitors blocks testosterone
    metabolism to produce a 25 decrease in prostate
    volume. Better for large fleshy glands. 5 of
    patients get hot flushes, and can also cause
    gynaecomastia. Finasteride is the only drug in
    this group.

100
Surgical management of prostatic obstruction
  • A variety of operations has been tried, such as
    prostatic microwave, cryoablation, and
    transurethral incision of the prostate.
  • However, none has replaced TURP (Trans-urethral
    resection of prostate), which remains the gold
    standard.
  • TURP is not always successful, however. The most
    common early complication is failure to void
    after catheter removal (6). There is also a
    small risk of incontinence from external
    sphincter damage.
  • And finally After TURP erectile failure may be
    produced, and ALWAYS retrograde ejaculation is
    caused.

101
Prostatic carcinoma
  • 4th commonest cancer death, after lung,colon and
    breast.
  • Rare before age 40, peak incidence in 70s.
  • 70 arise in the peripheral zone of the prostate.
  • Most often found on PR or PSA testing
  • 40 have metastases at the time of diagnosis.

102
Prostate Carcinoma
  • Suspected on digital rectal examination or a
    raised PSA.
  • Diagnosed by BIOPSY, or found at TURP.

103
Further investigation
  • Is the prostate cancer
  • Metastatic ( Only treatable with Hormones)
  • Locally advanced (Hormones or radiotherapy)
  • Confined to the prostate (Hormones, Radio or
    Surgery)
  • Staging of prostate cancer requires an isotope
    bone scan. In patients under 75 years, where
    surgery or radiotherapy are being considered, a
    CT scan is also required.

104
Staging (TNM)
  • T1a Tumor in lt5 TURP specimen, incidental
    finding.
  • T1b Tumor in gt5 TURP specimen, incidental
    finding.
  • T1c Tumor non-palpable, diagnosed on biopsy.
  • T2a Palpable, half a lobe or less
  • T2b Palpable, half to all of one lobe
  • T2c Palpable, involves both lobes.
  • T3a Unilateral extracapsular extension
  • T3b Bilateral extracapsular extension
  • T3c Tumor invades seminal vesicles
  • T4a Invades bladder neck, external sphincter or
    rectum
  • T4b Invades levator muscles, or is fixed to
    pelvic side-wall.
  • N0 No lymph node metastases
  • N1 Single node metastasis, below 2cm in size
  • N2 Mets to a single node between 2 and 5 cm, or
    multiple nodes less than 5cm.
  • N3 Lymph node metastasis gt 5cm
  • M0 No Metastases.
  • M1 Metastases

105
Treatment - Surgery
  • For prostate cancer without metastases, which is
    confined to the prostate, PSA is below 15, and
    age below 70, consider RADICAL PROSTATECTOMY.
  • Major intra-abdominal procedure, with significant
    morbidity. Almost inevitably produces total
    erectile failure, and a variable degree of
    incontinence. Incontinence tends to improve /
    resolve with pelvic floor exercises.
  • 5 year disease-free survival for T2 cancer with
    surgery is 80

106
Treatment - Radiotherapy
  • Consider in males with disease that has spread
    locally outside the prostate below age 75. Also
    for prostate confined disease in men below 70
    years, unfit for surgery, and without metastases.
  • Can be given as external beam or brachytherapy
    (implanted radioactive particles within the
    prostate)
  • Complications
  • Bladder Frequency, Urgency, Haematuria.
  • Bowel Diarrhoea, Tenesmus, PR bleeding.
  • Skin Rash
  • Rarely, fistulas may be caused.
  • 5 year disease free survival for T2 disease is
    70 (Slightly lower than for surgery)

107
Treatment - Hormones
  • Prostate carcinoma is dependant on testosterone
    to survive. The medication used attempts to block
    testosterone synthesis. They are used in cases of
    metastatic disease or age gt75 years or unfitness
    for either surgery or radiotherapy for localised
    disease.
  • Gonadotropin analogues Goserelin, Leuprolin.
    Often given as monthly or 3-monthly injections.
    Initially produce a tumour flare, so can only be
    started after several days of an anti-androgen.
  • Anti-androgens Flutamide, Bicalutamide,
    Cyproterone acetate. Tablet form once daily.
  • Both of these medication groups produce
    significant side-effects most often hot-flushes,
    erectile failure, loss of libido, and
    gynaecomastia.
  • Treatment can be combined, using both a GNRH
    analogue and an anti-androgen. On average a
    2-year response is achieved until the development
    of Hormone-resistance. Alterative drugs for
    advanced disease include Oestrogens and
    Estramustine.

108
Ooh, Controversy!
  • In elderly men, i.e. age greater than 75, there
    is an argument for not investigating an
    asymptomatically raised PSA.
  • The reason is that at this age, there is a
    significant chance they will die of something
    else, and the only treatment would be Hormonal
    manipulation anyway. Some argue that treatment
    should be witheld until the development of
    outflow symptoms or metastatic discomfort, and
    then instituted.
  • The idea is to avoid needlessly treating and
    worrying elderly men

109
Urinary tract Calculi
  • Ureteric Calculi Most pass without difficulty,
    especially if below 5mm in diameter. Above 7mm
    they are unlikely to pass.
  • If calculi are not passing, or if they are
    causing blockage of the kidney as shown on IVP,
    then they can be removed endoscopically using a
    Ureteroscope and either Laser or EHL or basket
    extraction. If theres a lot of ureteric swelling
    then a stent can be left in for 4-6 weeks and
    then removed.
  • Ureteric calculi can be a symptom of a raised
    serum Calcium, so remember to check it!

110
Urinary tract Calculi
  • Renal Calculi
  • Generally present either as a cause of recurring
    infections or a cause of pain in the loin or
    flank. If large enough, they can seriously
    compromise renal function. This can be detected
    using a DMSA scan.
  • In a functioning kidney, stones up to about 2cm
    can be fragmented with ESWL sessions, which may
    be multiple. Larger stones or multiple stones may
    be dealt with operatively using PCNL, where a
    tube is inserted though the flank into the renal
    pelvis, and the stones surgically fragmented and
    removed. Very large stones may need to be removed
    using an open pyelolithotomy.
  • If the kidney is non-functioning then it can be
    removed.
