Multichannel urodynamic testing is commonly used to diagnose urodynamic stress incontinence (USI). It has been claimed that USI may be diagnosed by imaging. In this study we determined the predictive value of ultrasound findings for USI.
This is an observational study utilising data obtained during urodynamic testing. Data sets were analysed in 209 patients in order to determine the predictive value of sonographic findings for the diagnosis of USI.
Bladder neck descent and maximal urethral pressure were the only independent predictors of USI identified by multivariate logistic regression. The finding of a cystourethrocele with funnelling increased the odds of a diagnosis of USI by 2.5 (95 % confidence interval 1.17-5.4, p = 0.018).
Translabial ultrasound can identify an anatomical configuration that is associated with USI. However, sonographic findings are insufficient to predict USI and can not replace urodynamic testing.
多通道尿动力学检测常用于诊断尿动力学压力性尿失禁（USI）。有人声称USI可通过影像学诊断。在本研究中，我们确定了超声检查结果对USI的预测价值。
这是一项利用尿动力学检测期间获得的数据进行的观察性研究。对209例患者的数据集进行分析，以确定超声检查结果对USI诊断的预测价值。
膀胱颈下移和最大尿道压是多因素逻辑回归确定的仅有的USI独立预测因素。发现伴有漏斗形成的膀胱尿道膨出使USI诊断几率增加2.5倍（95%置信区间1.17 - 5.4，p = 0.018）。
经阴唇超声可识别与USI相关的解剖结构。然而，超声检查结果不足以预测USI，不能替代尿动力学检测。
