Abstract

PURPOSE:

Neobladder reconstruction using an intestinal segment is the common procedure of choice in men after cystectomy. Recently this procedure has been extended to women. We present our surgical and functional experience with the sigmoid neobladder in women.

MATERIALS AND METHODS:

A total of 11 women 49 to 74 years old (mean age plus or minus standard deviation 60 +/- 8.5) with transitional cell carcinoma of the bladder underwent lower urinary tract reconstruction with a modified sigmoid neobladder after nerve and urethral support sparing cystectomy. After at least 3 months voiding pattern and continence status were evaluated. Pressure flow studies and uroflowmetry were performed, the urethral pressure profile and neocystourethral angle were measured, and blood chemistry was analyzed.

RESULTS:

After at least 3 months complete daytime continence was achieved in 2 patients, while 8 had mild stress incontinence. At night 8 of the 11 women (72.7%) were continent with or without voiding at regular intervals. All except 1 patient voided to completion. Of the 2 patients with complete continence 1 needed clean intermittent catheterization 4 months postoperatively. Mean maximal urinary flow was 19.9 +/- 10.5 ml. per second. Excluding the woman who required catheterization mean residual urine volume was 15 +/- 13.7 ml. Postoperatively maximal urethral pressure was slightly lower and functional urethral length was about 10 mm. shorter than preoperatively. The mean neocystourethral angle was 131.9 +/- 21.7 degrees. Mean pH, bicarbonate and base excess were 7.38 +/- 0.03, 23. 48 +/- 2.34 mmol./l. and -0.92 +/- 2.50, respectively.

CONCLUSIONS:

After nerve and urethral support sparing cystectomy a modified sigmoid neobladder may be constructed in women to obtain satisfactory continence and voiding results.
