Measuring the urethral circumference accurately during artificial urethral sphincter (AUS) placement is an important technical aspect to optimize the selection of cuff size. Differing methods exist for this step with some experts recommending measurement with no urethral catheter in place. In this prospective observational trial, we compared urethral measurements with and without an indwelling catheter to determine if the presence of a catheter affects the circumferential measurement.

在AUS放置期间，尿道内导管置入不会改变尿道的外周尺寸：一项前瞻性观察性试验。

在人工放置尿道括约肌（AUS）期间准确测量尿道周长是优化袖带尺寸选择的重要技术方面。对于这一步骤，存在不同的方法，一些专家建议在不使用导尿管的情况下进行测量。在这项前瞻性观察性试验中，我们比较了有和没有留置导管的尿道测量结果，以确定导管的存在是否会影响圆周测量。
