Abstract:
Objective To investigate the effects of partial prostatic capsula and surrounding striated sphincter sparing surgery on the function of intestinal orthotopic neobladder. Methods Total cystectomy and orthotopic intestinal neobladder was performed in 23 male patients with invasive bladder cancer. The patients were divided into classical cystectomy group (n=10) and modified cystectomy group (n=13).In the classical group the prostate was removed completely and the residual urethra was anastomosed with the neobladder using interrupted suture.In the modified group transurethral resection of the prostate preceded the cystectomy,and the prostatic capsula below the verumontanum with its surrounding striated urethral sphincter was retained.The neobladder was anastomosed with the residual capsula using continuous suture.The function of the neobladder in the 2 groups was evaluated and compared. Results The pathological classification of the 23 patients was as follows:T 2aN 0M 0,13 cases;T 2bN 0M 0,6;T 1N 0M 0,1;T 3aN 0M 0,1;T 3bN 1M 0,1;T 4aN 0M 0,1.The patients were followed up for 3 to 40 months(mean,15.7 months).In modified group,11 patients survived disease-free and 2 survived with metastasis.All the 13 patients voided well with residual volume of 0 to 70 ml.Complete urinary continence was achieved in 12 patients and the remaining one had nocturnal incontinence.In classical group,10 patients survived disease-free;of them 7 voided well with residual volume of 10 to 100 ml and the other 3 needed intermittent catheterization because of their residual urine being up to 100 to 250 ml.Complete continence was achieved in 7 patients and the other 3 were incontinent(1 with incontinence day and night,2 with nocturnal incontinence). Conclusions Partial prostatic capsula and its surrounding striated sphincter sparing surgery can improve the continence and voiding of the orthotopic neobladder.$$$$
