To assess the prevalence of stress urinary incontinence symptoms in young, nulliparous, physically fit women, evaluate their clinical and urodynamic characteristic, and compare them to a matched asymptomatic control group.
All first-year physical education students (N = 37) were asked to participate in a four-step study on urinary incontinence. The study included an interview, a clinical examination (incorporating an assessment of pelvic floor muscle strength), ambulatory urodynamics during exercise, and a needle electromyographic assessment of pelvic floor muscles and the striated urethral wall muscle with simultaneous urethral and bladder-pressure measurements.
Thirteen (38%) subjects reported stress urinary incontinence symptoms. Eight of the 13 reported the condition to be a social or hygienic problem; six experienced leakage more than once a week. The mean quantity of leakage of the symptomatic women during ambulatory urodynamics was 12 g (range 0-43). No uninhibited detrusor contractions were detected during leakage episodes. Six of seven subjects with symptoms were found to have urodynamic evidence of urethral sphincteric incompetence. There were no differences between the symptomatic and the control group in body mass index, percent body fat, pelvic floor muscle strength, menstrual cycle, and electromyographic patterns. Four of seven women in the symptomatic group had benign hypermobility joint syndrome, whereas there were none in the control group.
Physically fit nulliparous women have a high prevalence of stress incontinence symptoms and evidence of urethral sphincteric incompetence.
评估年轻、未生育、身体健康的女性压力性尿失禁症状的患病率，评估其临床和尿动力学特征，并与匹配的无症状对照组进行比较。
所有一年级体育专业学生（N = 37）被要求参与一项关于尿失禁的四步研究。该研究包括一次访谈、一次临床检查（包括盆底肌肉力量评估）、运动期间的动态尿动力学检查，以及对盆底肌肉和尿道横纹肌进行针电极肌电图评估并同时测量尿道和膀胱压力。
13名（38%）受试者报告有压力性尿失禁症状。13名中有8名报告该情况是一个社交或卫生问题；6名每周漏尿不止一次。有症状女性在动态尿动力学检查期间的平均漏尿量为12克（范围0 - 43克）。漏尿期间未检测到逼尿肌无抑制性收缩。7名有症状的受试者中有6名有尿道括约肌功能不全的尿动力学证据。有症状组和对照组在体重指数、体脂百分比、盆底肌肉力量、月经周期和肌电图模式方面无差异。有症状组的7名女性中有4名患有良性关节过度活动综合征，而对照组中没有。
身体健康的未生育女性压力性尿失禁症状的患病率较高，且有尿道括约肌功能不全的证据。
