The continent sigmoid urinary reservoir--an experimental study in pigs.
OBJECTIVE
To evaluate the function of a continence mechanism in combination with a colonic urinary reservoir in a pig model.


METHODS
A colonic urinary reservoir was constructed as a bladder augmentation in six domestic pigs. The pouch was connected to a narrowed and tunnelled ileal tube as a continence mechanism. The closure pressure was measured intra-operatively and 3 months post-operatively.


RESULTS
The mean difference between the pressure in the continence mechanism and in the reservoir was 74 cmH2O (range 50-100). Continence was complete both intra-operatively and 3 months post-operatively.


CONCLUSIONS
The modified narrowed and tunnelled ileal tube is a safe continence mechanism when combined with a colonic urinary pouch.
