Abstract
One hundred nine women were evaluated for urinary incontinence. A clinical diagnosis was assigned on the basis of history and physical examination. Urodynamic testing was then performed and included a measurement of postvoid residual urine, cystometrogram with concomitant urethral electromyography, urethral pressure profile, assessment of the transmission pressure capacity ratio, and cystourethroscopy. The findings of the urodynamic testing were compared with the clinical diagnosis. Clinical diagnosis showed a 100% sensitivity for the presence of stress urinary incontinence and a 78% sensitivity for stress urinary incontinence as genuine. Twenty cases of unsuspected urethral pathology were identified. Thirteen of these were discovered by urethral electromyography. Urodynamic testing is demonstrated to be necessary in the evaluation of urinary incontinence. (J GYNECOL SURG 5:93, 1989)
