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.
将19名患有压力性尿失禁（SUI）且尿道压力低的女性与106名患有SUI且尿道压力正常的患者进行了比较。所有患者均接受了改良的佩雷拉手术或布奇耻骨后尿道悬吊术，并且在手术前和术后一年都进行了详细的临床和尿动力学评估。手术有效地稳定了膀胱底部，并使两组女性的腹部压力都能充分传递到尿道。尽管有这些尿动力学检查结果，但与尿道压力正常的女性相比，压力性尿失禁且尿道压力低的女性的失败率显著更高（佩雷拉手术为50%对23%，布奇手术为33%对12%[p<0.05]），这表明她们尿失禁的病因并非是对尿道膀胱连接部的支撑不足；因此，需要另一种方法来治疗压力性尿失禁。
