The present work was performed to evaluate the clinical usefulness of colposuspension in stress urinary incontinence without uterovaginal descent and bladder neck suspension in cases with uterovaginal descent. Modified Burch colposuspension was performed in 29 patients and modified Raz bladder neck suspension in 19 patients. The patients were examined clinically and urodynamically before and 8-12 months after operation. All patients in the colposuspension group regarded themselves as being totally continent postoperatively. In the bladder neck suspension group the respective figure was 58%, plus 21% showing improvement and 21% failures. Urodynamically, the cure rates (positive urethral closure pressure at stress) were 100% for colposuspension and 79% for bladder neck suspension. After colposuspension the urethral closure pressure at stress and the pressure transmission ratio were significantly increased whereas successful bladder neck suspension increased only urethral closure pressure at stress. The failed bladder neck suspensions did not induce any urodynamic changes. The present data confirms that Burch colposuspension is effective in stress urinary incontinence in women without simultaneous uterovaginal descent, whereas bladder neck suspension by the modified Raz technique did not appear to be optimal for the treatment of stress incontinence in patients with uterovaginal descent.
