Stress urinary incontinence was evaluated urodynamically in 86 women in private urologic practice. While 31 patients had failed prior surgical repairs and 58 patients (67.4 per cent) reported irritative symptoms of frequency, nocturia, urgency and urge incontinence unstable bladders were found in only 5 women (5.8 per cent) over-all, in 6.5 per cent of those patients failing a previous operation and in 8.6 per cent of those patients with irritative symptoms. Urethral pressure profiles were decreased mildly in patients with, compared to those without, stress urinary incontinence but considerable overlap existed and no improvement was seen in 20 patients cured with an operation. Excretory urography, post-voiding residual urine volumes and sphincter electromyography usually were normal. Women with stress urinary incontinence consistently showed poor transmission of cough to the urethra so that the intravesical pressure exceeded the intraurethral pressure.
在一家私人泌尿科诊所对86名女性进行了尿动力学评估，以确定压力性尿失禁情况。其中31例患者既往手术修复失败，58例患者（67.4%）报告有尿频、夜尿、尿急和急迫性尿失禁等刺激性症状。总体而言，仅5名女性（5.8%）发现有不稳定膀胱，既往手术失败的患者中这一比例为6.5%，有刺激性症状的患者中这一比例为8.6%。与无压力性尿失禁的患者相比，有压力性尿失禁的患者尿道压力曲线轻度降低，但存在相当大的重叠，并且在20例手术治愈的患者中未见改善。排泄性尿路造影、排尿后残余尿量和括约肌肌电图通常正常。压力性尿失禁的女性始终表现出咳嗽向尿道的传导不佳，以至于膀胱内压超过尿道内压。
