Bladder neck mobility and the outcome of surgery for genuine stress urinary incontinence. A logistic regression analysis of lateral bead-chain cystourethrograms.
Bladder neck position, as determined by preoperative and postoperative resting and straining lateral bead-chain cystourethrograms, was analyzed by logistic regression analysis in 94 women undergoing 98 operations for genuine stress incontinence. A total of 384 roentgenograms were analyzed in an attempt to build a model that would predict the likelihood of surgical success in a given patient based on the preoperative films and explain a successful surgical outcome based on the characteristics of the postoperative films. The most important predictors of success were the number of previous incontinence operations, a large distance between the bladder neck and the pubic symphysis at rest, and increased mobility of the bladder neck before surgery. Successful surgery appeared to be related most closely to decreasing mobility of a previously hypermobile bladder neck.
