Haematuria –Investigations and when to refer Mr Peter Liodakis Urological Surgeon Austin Hospital, Box Hill Hospital Epworth Richmond Warringal Private Hospital
malignancy & macroscopic haematuria cystoscopy • urine cytology • USS ± IVP cancer 24.7 % Alishahi S; J R Coll Surg Edinburgh 47 2002 422-427 maligna
Macroscopic Haematuria • always abnormal but a cause is not always found • may not represent serious life threatening disease • always a need to seek an explanation • cancer always needs exclusion • cancer unlikely age < 40
Causes • Cancer • Infection, Injury , Inflammation • BPH and prostatitis • Stones • interstitial kidney disease • cystitis & urethritis • Urethral caruncle • no cause found
Macroscopic Haematuria • Clot retention versus episodic • Clot retention- management • Refer to emergency department • Large irrigating catheter • Bladder washouts • Investigate cause
Episodic Haematuria • More commonly seen in General practice • Time to investigate • All patients require: • MSU • Urine cytology • Upper tract imaging • Cystoscopy • PSA for male
MSU, M,C +S • infection, morphology of red cells • Cytology- not if current frank haematuria • Good for high grade urothelial lesion • Low sensitivity for low grade TCC • Therefore negative cytology and imaging does not preclude need for cystoscopy • Newer Markers (NMP -22, FISH)
Upper Tract Imaging • Traditionally- Ultrasound and IVP • U/S- to exclude cortical lesion • 80-90% sensitivity • IVP- to exclude urothelial lesion • 60-70% sensitivity
CT-IVP- • Highest sensitivity>90% sensitivity • Looks at both cortex and urothelium • Significant radiation exposure
Cystoscopy • Flexible or rigid cystoscopy • Flexible- if all preceeding tests are normal • Rigid- if any abnormality in tests or higher index of suspicion
Microscopic Haematuria • Not Evident to the naked eye • More than 3-5 cells per HPF • More than 10 RBC’s per microlitre • If found on dipstick – should have a formal urine microscopy
How common is microscopic haematuria? point prevalence in asymptomatic adults: • < 1% < age 40 & 13% age > 40 • 4 - 13 % healthy adults * • 9.4 % in Australian community ** • 2.0 % insurance applicants *** * International Journal of Clinical Practice 61(5) May 2007 ** Chadban SJ ANZ Society Nephrology 2000 *** Wright WT Archives Internal Med 1959
Likelihood of finding Cancer % females vs age microscopic macroscopic 10-19 0.0 0.0 20-29 0.0 0.0 30-39 0.0 4.0 40-49 2.9 10.8 50-59 1.9 8.9 60-69 4.5 21.1 70-79 4.5 20.5 80-89 15.8 41.7 Khadra J Urology 2000
Microscopic Haematuria • Diagnostic yield is lower • All potential causes of Macro can cause micro • Stratify investigations • Exclude menstruation, exercise induced, trauma • Imapaired renal function, FHx of renal disease , HT – suggestive of renal cause
Microscopic Haematuria • If persistent proteinuria is present , should see a Renal Physician (>2gm in 24 hour collection) • Low protein to creatinine ratio is a reliable indicator of low urinary protein • Up to 40% may have nephropathy not all of which will progress to ESRF
Case 1 • 70 y/o male • 3 year moderate LUTS • Treated with Flomaxtra • 2 x frank haematuria • Baseline bloods –NAD, PSA 2.7 • Urine Micro – no growth, Cytology - Neg • CT IVP – NAD • Cystoscopy – Large vasc Prostate
Options • Finasteride (Proscar) or Dutasteride (Avodart) • Inhibits conversion Testosterone to DHT • Up to 85% reduction in incidence of bleeding • At least 3 weeks to take effect • Surgery • TURP • Green Light Laser • Open prostatectomy
Case 2 • 68 y/o female • HOPC • Worsening frequency past 4 months • Frank Haematuria 2 days • PHx • HT, Chol, OA • Smoker (40 pkt year history) • Examination • unremarkable
FBE, U+E’s, LFT’S, COAGS – NAD • MSU • RBC’s +++ • No Growth • Cytology • No malignant cells • CT IVP • Bladder filling defect, could be TCC, could be blood clot • Cystoscopy
Bladder TCC • Males 3 : 1 Females • Women have more than a 30% higher chance of dying of bladder cancer • 4th most common cancer in men • Rare in persons younger than the age of 50 • median ages at diagnosis of 70 yrs
Bladder Cancer Risk Factors • Cigarette smoking increases risk fourfold • Environmental carcinogens • Aromatic amines • Painter, autoworker, metal worker, dry cleaner • Previous Irradiation • Cyclophosphamide • Long term catheters (SCC) • Analgesic Abuse (Phenacetin) • 90% Bladder cancers are TCC (others SCC Ad)
Case 3 • 61 y/o male • Previously fit and well • 3 episodes of frank haematuria • No LUTS • Ex-smoker (20 pkt year History) • Worked in Dry cleaning Business 15 yrs
Examination – Unremarkable • FBE, U+E’s, LFT’S, COAGS, PSA – NAD • Renal Tract U/S • Normal renal contours • No Hydronephrosis or hydroureter • 46 gm prostate • MSU • RBC’s +++ • No Growth • Cytology • Suspicious cells for TCC • Cystoscopy
Upper Tract TCC • Same risk factors as for bladder TCC • Nephro-ureterectomy is treatment of choice (laparoscopic) • 75% involve renal pelvis • Ureteric tumours can be adequately treated with ureteric excision and re-implantation of ureter • Ongoing surveillance for recurrence
Case 4 • 64 yo male with flank pain • Anorexia past 2 months • Weight loss 7kg • Previously fit and well • Palpable mass in L) UQ • L) varicocele
Investigation results • Hb 110, plt 478 • ESR 139 • Calcium 2.71 • LFT’s, Coags, U+E’s – NAD • CT scan
Renal cell Cancer • Haematuria, flank pain, mass (10%) • 70% incidental finding • 30% present with metastases • (6-12 month median survival) • Paraneoplastic syndrome in up to 30% • Hypercalcaemia, anaemia, ESR, CRP • Associated with poor prognosis
Small renal Masses • 70% less than 4 cm • Up to 15% are benign • Renal Biopsy accuracy 72% • Risk of metastases -2% • Growth rate 0.3 cm year
Management • Active Surveillance • 3000 pts, median size 2.5 cm • 30 month follow up, <1% metastases • Nephrectomy • Lap vs open • Partial Nephrectomy • Lap vs open • Ablative treatment
