[Application of low tension Roux-y sigmoid neobladder in urine diversion].
OBJECTIVE
To assess the therapeutic effects of low tension, anti-reflux Roux-y sigmoid neobladder.


METHODS
A total of 21 patients (7 male and 14 female) were included, aged 43-87 years. All cases received radical cystectomy and low tension Roux-y sigmoid neobladder procedure for invasive bladder cancer were included in this study. The period of follow-up was from 8 to 79 months (the average was 36 months). Evaluations included urinary flow rate, post voiding residual and filling cystometry.


RESULTS
The mean maximum urinary flow rate, the voiding time and the post voiding residual were 28.1 ml/s (21.4-38.4 ml/s), 17 s(9-28 s) and 0 ml respectively. The cystometric capacity was 480 m1 (350-560 ml). The volume of desire to void was 330 ml (120-410 ml). The bladder pressure was from 14.2 to 18.6 cm H2O (the average bladder pressure was 16.4 cm H2O) at high filling volumes. The maximum voiding pressure was 45.0 cm H2O (23.6-63.4 cm H2O).


CONCLUSIONS
The Roux-y sigmoid neobladder has an adequate capacity at low pressure with a satisfactory continence, and it is an effective method for continent urinary diversion.
