ABSTRACT
OBJECTIVE:
To evaluate the urodynamics and functions of upper urinary tract in a substitute of orthotopic T pouch ileal bladder.METHODS:
From June 2004 through September 2009, 90 patients underwent the construction of an orthotopic T pouch ileal neobladder after radical cystectomy for muscle-invasive bladder cancer. The radiographic or ultrasound evaluation of upper urinary tract, determination of renal functions and urodynamic evaluation of T pouch ileal neobladder were performed by data analysis.RESULTS:
Renal function as determined by serum creatinine remained in a normal range in all patients. Temporary dilation of renal pelvic and ureter was observed in 18 patients (20.0%) at Day 45 post-operation and then disappeared spontaneously in the late follow-up. A slight dilation of collecting system was found in other 4 patients (4.4%), but there was no negative impact on renal function. Reflux into afferent limb of neobladder was observed in 4 patients (4.4%) by cystography. Excellent daytime and nighttime continence was reported in 100% and 82.2% of evaluated patients respectively. The urodynamic assessment showed a mean capacity of (316 ± 96) ml with a mean intra-bladder pressure of (16 ± 10) cm H2O. These evaluated patients voided with a mean maximum intra-bladder pressure of (87 ± 25) cm H2O, a mean maximum flow rate of (17 ± 10) ml/s and a mean residual urine of (33 ± 29) ml.CONCLUSION:
With an intermediate follow-up, the functional results of T pouch ileal neobladder are encouraging with an excellent capacity and compliance, successful daytime and nighttime continence and anti-reflux mechanism.
