目的:探讨女性压力性尿失禁患者在不同膀胱灌注量下漏尿点压的差异。方法:回顾性分析2016年1月至2018年12月本院收治的12例女性压力性尿失禁患者，在术前行尿动力检查时分别给予膀胱灌注200、250、300、350 mL时，测出腹压漏尿点压及咳嗽漏尿点压并分别进行比较。结果:不同膀胱容量下同时测得的腹压漏尿点压及咳嗽漏尿点压比较，差异均无统计学意义(n P>0.05)。n 结论:当对女性压力性尿失禁患者进行术前尿动力检查时，如果膀胱灌注200 mL时无漏尿，可继续增加膀胱容量直至漏尿。“,”Objective:To investigate the difference of pressure of urine leakage point in female patients with stress incontinence at different perfusion volumes.Methods:Retrospective analysis of 12 female patients with stress incontinence treated in our hospital from 2016 to 2019, during the preoperative urodynamic examination, 200, 250, 300 and 350 mL bladder perfusion were performed respectively.Abdominal leak point pressures and cough leak point pressures were measured in different bladder volumes.Results:There was no statistically significant difference between the lower abdominal pressure and cough urine leakage point pressure of different bladder volumes.Conclusions:When preoperative urodynamic examination is performed on patients.If the bladder is perfusion of 200 mL, and there is no urine leakage.Bladder volume may continue to increase until urine leakage.
