BLADDER NECK MOBILITY AND THE OUTCOME OF SURGERY FAR 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 analy zed by logistic regression analysis in 94 women undergoing 98 operatio ns for gen uine stress incontinence. A total of 384 roentgenograms wer e analyzed in an attempt to build a model that would predict the likel ihood of surgical success in a given patient based on the preoperative films and explain a successful surgical outcome based on the characte ristics of the postoperative films. The most important predictors of s uccess were the number of previous incontinence operations, a large di stance between the bladder neck and the pubic symphysis at rest, and i ncreased mobility of the bladder neck before surgery. Successful surge ry appeared to be related most closely to decreasing mobility of a pre viously hypermobile bladder neck.
