Two types of micturitions of ileal neobladder.

Eight patients were evaluated clinically, radiologically, and urodynamically to determine the outcome of continent urinary diversion with ileal neobladder performed to treat the recurrent superficial bladder cancer after cystectomy with subcapsular prostatectomy. The mean age of the patients was 55.3 years. After descending dissection of the urinary bladder without ligation or dissection of Santorini's plexus, the prostate was cut to the bladder neck distally for 2 cm under the subcapular prostatectomy. One patient who had a short 3 cm intestinal segment between the pouch and the urethra, had severely prolonged micturition with peristalsis in this short segment, and required a re-operation. Micturition was good in the other seven patients, all with detubularized neobladder directly to the prostate capsule in anastomosis. Pressure flow studies performed on these seven patients revealed two types of micturition; "fast bladder" and "intermittent flow", the latter resembling detrusor sphincter dyssynergia.
