Haematuria causes
Renal: Congenital: PCKD Trauma Infection Neoplasm Immune: GN (HSP), TIN
Extra-renal:
Trauma: stones, catheter
Infection: Cystitis, prostatitis, urethritis
Neoplasm: Bladder/prostate
Bleeding diathesis
Drugs: NSAIDs, frusemide, cipro, cephalosporins
Urological causes of haematuira
Cancer (TCC or RCC)
Stones - kidney, ureter, bladder
UTI: Cystitis, pylonephritis
Trauma
BPH or prostate cancer
Transient causes: UTI, exercise , menstruation, myoglobinuria
When to Ix haematuria
Ix in pts with:
- Visible haematuria
Standard male size catheter?
Usual size used for males is 14 / 16 Fr
Complications of catheterisation?
1) Local trauma
2) Introduction of infection
3) Urethritis
4) Stricture formation
When would you use a suprapubic catheter?
1) Urethral cath. not possible (Urethral stricture)
2) Urethral cath inappropriate: Urethral tauma suspected eg. pelvic injury with a high riding prostate
(Prostate + Prosthatic urethra torn from urethra and pulled upwards, thus the prostate feels too far up on PR)
What % of pts with frank haematuria have a urological malignancy?
35%
–> Suspect RCC or blader cancer
Haematuria causes: Local vs General
Local: Bleeding anywhere along urinary tract: Kidneys, ureters, bladder, prostate or urethra
General causes
Haematuria History Questions?
1) Blood deffo in urine and not from vag/butt?
2) True Haematuria? other causes of red urine:
- Drugs (rifampicin, nitro)
- Foods : Beetroot
- Systemic disease: Porphyrias / rhabdo
3) Associated with loin pain or pain on passing urine?
- Pain = stone/infection
- Painless = !! ?malginancy
4) Nature of bleeding:
- Micro/macroscopic
- Clots
- Beginning of otherwise clear stream? (Suggestive of urethral/prostatic lesion
- Throughout stream? (suggestive of bladder, ureter, kidney lesion)
- Bleeding at end of stream - Schisto
Haematuria Ix?
One stop Haematuria clinic
- Urine test: MSU Dipstick, MC+S, Cytology
- Haematological tests: FBC (Anaemia), U+E (renal function)
- Radiological: USS of renal tract. If mass, CT.
X-ray KUB = IVU (Intravenous urogram)/ CT IVU
Special investigatinos:
In which pts would haematuria always be investigated, and how?
For pts with Macroscopic haematuria and persistent microscopic haematuria
- US + cystoscopy should ALWAYS be performed.
If these are normal, then an IVU or CT IVU should be requested, particularly in pts > 50
Bladder outflow obstruction causes
Most common:
Other:
Bladder neck obstruction?
Affects young to middle aged men
Due to bladder neck dysfunction
Tx:
Medical (Drugs)
Surgical: Bladder neck incision
Urethral stricture - Causes and treatment
Causes: Urethral trauma Catheterisation Previous transurethral surgery STI eg. gonorrhoea/chlamydia
Tx:
Urethrotomy
Dilators
LUTS - Symptoms?
Obstructive:
Irritative symptoms:
BOO complications?
UTI (due to urinary stasis)
Formation of bladder calculi
Hydronephrosis + Subsequent renal impairment
Acute (painful) / Chronic (painless) retention
Prostate anatomy
capsulated fibromuscular gland, measuring 4x3x2cm, weighing 15g (walnut).
Which zone enlarges in BPH vs prostate cancer
BPH: transitional zone
Prostate cancer: Peripheral zone
BPH Sx + Cause?
Obstructive + Irritative symptoms
Ix:
1) Examination: Abdo to exclude retention. PR to check prostate (sulcus present + smooth surface but enlarged gland)
2) Urine: Dipstick, MC+S
3) PSA
4) IF PSA high when rechecked/suspicious prostate –> transrectal US + biopsy
5) Urine flow test
6) US of urinary tract to assess residual bladder volume and look for upper tract dilatation
? cystoscopy if stricutre/ bladder cacluli
? Urodynamic studies
? Voiding diary to see how much bother the symptoms cause the pt
PSA
Produced by prostatic acinar cells
BPH Mx
Mild Sx: Watchful waiting + R/V in clinic. 65% will not progress
Medical:
1)A1 blockers eg. Tamsulosin, prazosin, alfuzosin
–> Relax prostate smooth muscle, increase urinary flow _ help obstructive Sx
SE: uncommon, but include hypotension
2) 5AR inhibitors: Finasteride
Surgical
1) TURP - Gold standard
Newer:
TURP: Procedure
Pt placed in lithotomy positon
Resectoscope passed through urethra, used under direct vision to remove prostate piece by piece, using cutting diathermy. Chippings sent for histology.
Diathermy can also stop bleeding.
3 way catheter inserted post-op to irrigate bladder until fluid no longer heavily blood stained. Stops clots forming + blocking catherer.
TURP complications
Early:
Late:
Prostate cancer Sx? Ix?
Same symptoms as BPH - can be difficult to differentiate.
Diagnosed histologically after TURP for what was thought was benign disease.
- However now, most commonly PSA + prostate biopsy
PR: enlarged, ‘craggy’ prostate, hard nodule may be palpable. Midline sulcus may be lost.
If malignancy diagnosed, staging:
- Bone scan
- MRI abdopelvis
