Urethral axis position and mobility, as determined by the "Q-tip test," were measured in subjectively continent women (N = 26), women with genuine stress incontinence (N = 28), and women with other types of urinary incontinence and voiding dysfunction (N = 20). Diagnostic urodynamic evaluation in symptomatic women included standard history, physical examination, urine culture, Q-tip test, uroflowmetry, standing "stress test," resting and stress urethral pressure profiles, and subtracted medium-fill water cystometry with provocation. Multiple regression analysis was used to determine the existence of significant clinical predictors of the dependent variables (stress angle, urethral mobility). These factors were used as covariates to identify differences between the adjusted group means. The results indicate a wide range of values for each Q-tip test measurement in all groups. Age, parity, resting Q-tip angle, and the presence of anterior vaginal relaxation were associated with maximum stress Q-tip measurement. Significant differences in maximum stress Q-tip angle and urethral mobility were noted only between the continent controls and women with genuine stress incontinence. No differences were found between the two incontinent study groups. We conclude that urethral position and mobility as measured by the Q-tip test are related to defects in anterior vaginal support, but not to specific urologic diagnosis.
通过“棉签试验”测定了主观控尿的女性（N = 26）、真性压力性尿失禁女性（N = 28）以及患有其他类型尿失禁和排尿功能障碍的女性（N = 20）的尿道轴位置和活动度。有症状女性的诊断性尿动力学评估包括标准病史、体格检查、尿培养、棉签试验、尿流率测定、站立位“压力试验”、静息和压力状态下的尿道压力分布，以及激发状态下的中量充盈水囊膀胱测压。采用多元回归分析来确定因变量（压力角度、尿道活动度）的显著临床预测因素。这些因素被用作协变量以识别调整后的组均值之间的差异。结果表明，所有组中每次棉签试验测量值的范围都很广。年龄、产次、静息棉签角度以及阴道前壁松弛的存在与最大压力棉签测量值相关。仅在控尿对照组和真性压力性尿失禁女性之间观察到最大压力棉签角度和尿道活动度存在显著差异。两个尿失禁研究组之间未发现差异。我们得出结论，通过棉签试验测量的尿道位置和活动度与阴道前壁支持缺陷有关，但与特定的泌尿外科诊断无关。
