Thirty‐seven patients with proven genuine stress incontinence (GSI) underwent ultrasound study to evaluate the bladder neck position relative to the symphysis pubis. Sixty‐five continent women including 40 parous and 25 nulliparous women were recruited as a control group. Several parameters were found to be statistically different between incontinent and control groups ( P < 0.01). If 28 degrees or 13 mm were used as the cut‐off point for rotational angle (RA) and descent of bladder neck (DBN), the sensitivity, specificity, and positive and negative predictive values were 73.0%, 76.9%, 64.3%, and 83.3%, respectively. The specificity and positive predictive value for GSI increased to 83.1% and 67.6% if these two parameters were used together. Perineal sonography is valuable in assessing anatomic change of the bladder neck, but it is not a sensitive tool for predicting GSI. © 1997 John Wiley & Sons, Inc. J Clin Ultrasound 25:189–194, 1997
