To evaluate the association between the length of the female urethra and urodynamic study (UDS) parameters in patients presenting with stress urinary incontinence (SUI).
We retrospectively enrolled 391 women who underwent a transobturator adjustable tape sling implantation for the management of SUI between April 2009 and March 2016. All patients underwent a physical examination and UDS. Filling cystometry data that were evaluated included the Valsalva leak point pressure, and the cough leak point pressure. The maximal urethral closure pressure, the functional urethral length (FUL), and the length of the continence zone (LCZ) were measured using the urethral profile obtained from the UDS. The anatomical urethral length (AUL) was measured intraoperatively using a Foley catheter. We calculated the LCZ/FUL ratio to determine the anatomical continence length for this study.
We noted that 299 patients completed the study. The mean AUL was 26.25±3.59 mm. The mean FUL and LCZ were 41.37±15.05 mm and 24.15±13.90 mm, respectively. The mean LCZ/FUL was 0.57±0.19. Using the Pearson correlation coefficient, we observed that the AUL showed a correlation with the FUL (0.168, =0.034), the LCZ (0.212, =0.007), the LCZ/FUL ratio (0.190, =0.016), the Valsalva leak point pressure (0.223, =0.005), the cough leak point pressure (0.215, =0.006), and the maximal urethral closure pressure (0.178, =0.043).
Our results show that the AUL in women is associated with UDS parameters relating to SUI.
评估压力性尿失禁（SUI）患者中女性尿道长度与尿动力学研究（UDS）参数之间的关联。
我们回顾性纳入了2009年4月至2016年3月间因SUI接受经闭孔可调节吊带植入术的391名女性。所有患者均接受了体格检查和UDS。评估的充盈性膀胱测压数据包括瓦尔萨尔瓦漏尿点压力和咳嗽漏尿点压力。使用从UDS获得的尿道轮廓测量最大尿道闭合压、功能性尿道长度（FUL）和控尿区长度（LCZ）。术中使用Foley导尿管测量解剖学尿道长度（AUL）。我们计算LCZ/FUL比值以确定本研究中的解剖学控尿长度。
我们注意到299名患者完成了研究。平均AUL为26.25±3.59毫米。平均FUL和LCZ分别为41.37±15.05毫米和24.15±13.90毫米。平均LCZ/FUL为0.57±0.19。使用Pearson相关系数，我们观察到AUL与FUL（0.168，P = 0.034）、LCZ（0.212，P = 0.007）、LCZ/FUL比值（0.190，P = 0.016）、瓦尔萨尔瓦漏尿点压力（0.223，P = 0.005）、咳嗽漏尿点压力（0.215，P = 0.006）以及最大尿道闭合压（0.178，P = 0.043）相关。
我们的结果表明，女性的AUL与SUI相关的UDS参数有关。
