Goals of the procedure:
- Complete safe resection of tumour
- Accurate pathological staging and grading
- Clinical staging with bimanual examination under anaesthesia
- Symptom relief (bleeding and irritation)
Steps:
- GA or spinal with antibiotic prophylaxis
- GA with neuromuscular blockade preferred if lateral wall tumour
- EUA
- Rigid cystoscopy with 30 and 70 degree lens
- Resection of tumour – complete visual resection with margin, ideally to muscular fibres
- Start from superficial and work deep
- I take a separate specimen from the base
- Haemostasis
- 3-way catheter with irrigation if needed
- EUA with empty bladder
Problems:
- Obturator nerve reflex – causing thigh adduction rapidly and risking perforation
- Muscle paralysis (? Consider obturator nerve block)
- Empty bladder
- ?Bipolar reduces risk
- Staccato technique
- Reduce cutting current
- Anterior or dome tumours (especially difficult in obese)
- Beware intraperitoneal perforation
- Modulate bladder volume
- Assistant’s hand for suprapubic pressure
- Longer resectoscope available
- Tumour over ureteric orifice
- Cut current only – less heat and minimises risk of obstruction
- Pinpoint haemostasis
- Consider need for ureteroscopy if concerns for ureteric disease
- Consider need for stent – risk of obstruction balanced with need for removal and theoretical risk of seeding/reflux up the ureter
- Tumour in diverticulum
- No muscle layer – can go from T1 straight to T3, be aware of perforation risk
- Consider sampling only with view to diverticulectomy vs aiming for complete resection
Complications of TURBT:
Perforation
- Consider if input ≠ output, suprapubic distension intra-operatively or in recovery, difficulty filling bladder, respiratory compromise
- On table cystogram or CT can diagnose and see if extraperitoneal or intraperitoneal
- Extraperitoneal can be managed with IDC for 10 days and repeat cystogram prior to removal
- Intraperitoneal should probably be managed with formal repair via laparotomy (and removal of urinoma, wash ++ of abdomen)
- Higher risk of extravesical malignancy
- Also risks TUR syndrome, infection
Bleeding
- May need to continue resecting to get to base of vessels and allow for haemostasis
- Ensure adequate irrigation, taps on etc
- If post-operative clot retention and bleeding – best managed back in theatre
Infection 3 – 5 %
Urinary retention, especially for bladder neck tumours
En-bloc resection is emerging as a technique for suitable exophytic tumours:
- Use Collin’s knife or laser to resect tumour in one piece, aiming for better and more accurate pathological assessment
Bipolar vs monopolar
- Suggestion of reduced obturator kick although this has not been proven in the literature.
- Systematic review failed to show difference in efficacy or safety
Presence of detrusor muscle in the specimen is considered a surrogate of resection quality.
Prostatic urethral biopsies recommended if:
- Bladder neck tumours
- Positive cytology without bladder tumour
- Suspicion of CIS
- Abnormalities visible
