Ileal T-pouch as a urinary continent cutaneous diversion: clinical and urodynamic evaluation.
OBJECTIVE
To report the functional results of continent cutaneous urinary diversion with ileum, using the serous-lined extramural valve and Mitrofanoff procedure for the continence mechanism.


METHODS
From April 1999 to October 2001, 18 patients (mean age 68 years) underwent radical cystectomy for invasive bladder cancer involving the bladder neck, urethra or prostate; they then had an ileal continent cutaneous T pouch constructed. The mean (range) follow-up was 12 (4-20) months. The first five patients had reconstructions using the original orthotopic T-pouch configuration, but in subsequent patients the technique was simplified, reducing the ileal segments. The ureteric-intestinal anastomosis was made using a split-cuff nipple technique.


RESULTS
All patients were continent day and night, and there were no late complications. All cutaneous continent T pouches had a good capacity and low pressure, with no urinary reflux. No catheterization difficulties were reported and the evacuation intervals were approximately 4 h.


CONCLUSIONS
This ileal cutaneous continent diversion is a versatile technique; the T-valve can be used successfully as a continent mechanism, ensuring continence day and night. The simplified technique maintains a reservoir of good capacity and compliance, thus preserving approximately 13 cm of ileal tract. The ureteric intestinal anastomosis by the split-cuff nipple technique is suitable in undilated and peristaltic ureters.
