To compare the predictive abilities of the Aa point of the pelvic organ prolapse quantification examination and the cotton-tipped swab test straining angle to diagnose urodynamic stress incontinence.
A case-control study was conducted between June 1997 and February 2003. Cases were defined as patients with urodynamic stress incontinence (n = 352). Controls were patients who also underwent urodynamic testing but who did not have a diagnosis of urodynamic stress incontinence (n = 245). Independent variables were defined as Aa point, Aa point of 0 or greater, straining cotton-tipped swab angle, and straining cotton-tipped swab angle of 30 degrees or greater. Logistic regression estimated the odds ratio of stress incontinence in women based on Aa values and cotton-tipped swab straining angle measurements, controlling for other variables commonly associated with stress incontinence.
The mean (+/- standard deviation) age of the cases was 55.9 +/- 13.4 and of controls was 55.3 +/- 14.8, (P = .6). The median parity of the cases was 2 (range 0-10) and of controls, 2 (range 0-9) (P = .7). The Aa point was not associated with a diagnosis of stress incontinence (odds ratio 1.01, 95% confidence interval (CI) 0.83-1.23). The adjusted odds ratios of having an Aa value of 0 or greater was 0.49 (95% CI 0.26-0.92), and of having a cotton-tipped swab angle of 30 degrees or greater was 3.1 (95% CI 1.09-5.07), in a model that adjusted for age, parity, race, and postmenopausal and hormonal replacement status.
Aa point is not associated with a diagnosis of stress incontinence. However, a cotton-tipped swab angle of 30 degrees or greater is positively associated with stress incontinence.
比较盆腔器官脱垂定量检查的Aa点和棉拭子试验用力角度对诊断尿动力学压力性尿失禁的预测能力。
于1997年6月至2003年2月进行了一项病例对照研究。病例定义为尿动力学压力性尿失禁患者（n = 352）。对照为同样接受尿动力学检查但未诊断为尿动力学压力性尿失禁的患者（n = 245）。自变量定义为Aa点、Aa点为0或更大、用力棉拭子角度以及用力棉拭子角度为30度或更大。逻辑回归基于Aa值和棉拭子用力角度测量值估计女性压力性尿失禁的比值比，并控制其他与压力性尿失禁通常相关的变量。
病例组的平均（±标准差）年龄为55.9±13.4，对照组为55.3±14.8（P = 0.6）。病例组的中位产次为2（范围0 - 10），对照组为2（范围0 - 9）（P = 0.7）。Aa点与压力性尿失禁的诊断无关（比值比1.01，95%置信区间（CI）0.83 - 1.23）。在调整年龄、产次、种族、绝经后和激素替代状态的模型中，Aa值为0或更大的调整后比值比为0.49（95% CI 0.26 - 0.92），用力棉拭子角度为30度或更大的调整后比值比为3.1（95% CI 1.09 - 5.07）。
Aa点与压力性尿失禁的诊断无关。然而，用力棉拭子角度为30度或更大与压力性尿失禁呈正相关。
