Sixty-one women with genuine stress incontinence undergoing preoperative and postoperative multichannel urodynamic investigation were tested with augmenting urethral closure pressure profiles during contraction of the pelvic floor muscles to assess voluntary control of the urethral "sphincter." Increases of 20% or more above resting functional length and closure pressure were selected as indicators of augmentation. The presence or absence of augmentation of functional urethral length and/or closure pressure during pelvic floor contraction allowed for the grouping of these patients into six subgroups which were compared for urinary symptoms, prior anti-incontinence procedures and the presence of low urethral pressure, detrusor instability and genuine stress incontinence both pre- and postoperatively. Evaluation of the patient's ability to augment functional length and closure pressure did not affect surgical success nor did its presence or absence correspond to the presence of a low pressure urethra, detrusor instability, or specific urinary symptoms. Evaluation of augmentation of functional length and closure pressure was therefore felt to be of no prognostic value during the performance of multichannel urodynamic testing in incontinent females.
对61名患有真性压力性尿失禁且接受了术前和术后多通道尿动力学检查的女性，在盆底肌肉收缩期间通过增加尿道闭合压力曲线来测试，以评估尿道“括约肌”的自主控制能力。将静息功能长度和闭合压力增加20%或更多作为增加的指标。根据盆底收缩期间功能性尿道长度和/或闭合压力是否增加，将这些患者分为六个亚组，比较其泌尿症状、既往抗尿失禁手术情况以及术前和术后是否存在低尿道压力、逼尿肌不稳定和真性压力性尿失禁。评估患者增加功能长度和闭合压力的能力既不影响手术成功率，其有无也与低压力尿道、逼尿肌不稳定或特定泌尿症状无关。因此，在对尿失禁女性进行多通道尿动力学检查时，评估功能性长度和闭合压力的增加被认为没有预后价值。
