Low urethral pressure and stress urinary incontinence in women: risk factor for failed retropubic surgical procedure.
Nineteen women with stress urinary incontinence (SUI) and low urethral pressure were compared with 106 patients with SUI and normal urethral pressure. All underwent either a revised Pereyra procedure or Burch retropubic urethropexy, and all had detailed clinical and urodynamic evaluations before their operation and one year postoperatively. Surgical procedures effectively stabilized the bladder base and enabled adequate abdominal pressure transmission to the urethra in both groups of women. In spite of these urodynamic findings, the failure rate in women with stress urinary incontinence and low urethral pressure was significantly higher compared with women with good urethral pressure (50% vs 23% for the Pereyra procedure and 33% vs 12% for the Burch procedure [p less than 0.05]), indicating an etiology for their incontinence other than poor support to the urethrovesical junction; therefore, the need for another approach to cure stress incontinence.
