National survey on orthotopic neobladder.
OBJECTIVE
A national survey was conducted among the urologists in India to find the preference for urinary diversion after radical cystectomy for muscle invasive carcinoma of the urinary bladder, percentage of neobladder reconstruction, segment of the bowel used, complication rate, need for self-intermittent catherisation on follow up and the survival.


METHODS
A detailed questionnaire was mailed to all members of the urological society of India (USI) to find out their preference for urinary diversion following radical cystectomy for muscle invasive carcinoma urinary bladder. For the neobladder reconstruction, they were asked for the type of bowel segment used, complication rate, reoperation rate, need for intermittent clean catheterisation on follow up and 5-year survival.


RESULTS
A total of 24 institutions responded to the mailed questionnaire. Of all institutions 12 (50%) did not prefer the orthotopic neobladder (ONB) reconstruction. Among the institutions carrying out neobladder reconstruction, majority perform ileal conduit in more than 50% of the cases. Ileum (66.66%) or ileocaecal (16.66%) segment was the choice of bowel segment for most of the urologists. Only three institutions used sigmoid colon. The complications encountered were wound infection (5-25%), burst abdomen (5%), urinary fistulas (3-25%), faecal fistulas (2-5%), bladder neck stenosis (5-15%) and ureterointestinal anastomosis stenosis (5-25%). The reoperation rate was 5-15% with a perioperative mortality of 0.5-3%. Around 10-100% (average 50%) of the patients require intermittent clean catherisation. Only seven institutions could provide 5-year survival rate data. Of these three institutions reported more than 50% and four institutes less than 50% 5-year survival.


CONCLUSIONS
Ileal conduit still remains the urinary diversion of choice following radical cystectomy for muscle invasive carcinoma of the bladder among most of the urologists in India. Orthotopic neobladder reconstruction is practiced only in selected centres. Wound infection, urinary leak and obstruction at ureterointestinal anastomosis are the main complications. Clean intermittent cathaterisation is required at an average of 50% of the patients to ensure complete emptying of the neobladder.
