Predicting postoperative urinary incontinence development in women undergoing operation for genitourinary prolapse.
A total of 67 female patients with pelvic relaxation (cystocele beyond the vaginal orifice) and with no urinary incontinence were clinically and urodynamically evaluated before and after a reconstructive surgical procedure. Of these, 24 patients had a significant decrease in abdominal pressure transmission to the urethra once the cystocele was reduced by vaginal pessary (abdominal pressure transmission ratio to urethra: bladder of less than 1.0). All 24 had a revised Pereyra procedure in addition to the cystocele repair. The other 43 patients had adequate abdominal pressure transmission to the urethra once the cystocele was reduced by vaginal pessary (abdominal pressure transmission ratio to urethra: bladder of greater than or equal to 1.0). These 43 patients underwent cystocele repair only with no surgical repair to the urethra or urethrovesical junction. Evaluation was repeated at 3 to 6 months after the operation. No patient developed urinary incontinence after operation. All 67 patients had urodynamically good abdominal pressure transmission to the urethra while coughing. Women with significant genitourinary prolapse may be continent in spite of a weak urethral sphincter because of kinking of the poorly supported urethra. Urodynamic testing can identify those women at risk of developing postoperative urinary incontinence so that prophylactic measures can be undertaken.
