Ultrasonography in urinary incontinence.

Linear array ultrasound techniques were utilized in place of conventional radiologic procedures to study the dynamics of the urethrovesical junction and proximal urethra in patients with urinary incontinence. This ultrasound procedure provided an objective demonstration of the mobility of the urethrovesical junction and documented the presence of an anatomic defect. It aided in the selection of patients suitable for surgical correction of stress incontinence and their postoperative follow-up. Ultrasound was also employed to demonstrate uninhibited detrusor contractions in patients with vesical instability.
