目的 探讨4种输尿管镜入镜方法的成功率及对输尿管口的损伤。 方法 回顾性分析2008年7月－2011年3月间行输尿管镜手术的患者共553例，按其入镜方法分为4组，分别采用球囊扩张法、灌注泵加压灌注入镜法、内旋法及倒入法进行输尿管镜操作。分析其成功率及对输尿管口的损伤。 结果 气囊扩张法成功率为95%，但对输尿管口的损伤率为100%；灌注泵加压法成功率为67.5%，输尿管口损伤率为87.0%；内旋法的成功率为87.9%，损伤率为50.0%；倒入法成功率91.0%，对输尿管口损伤率为22.2%。4种方法中，灌注泵加压法一次性成功率最低，与其余3种方法比较，差异均有统计学意义（P＜0.008）；其余3种方法间一次性成功率差异无统计学意义（P＞0.008）。对输尿管口的损伤率，4种方法组间两两比较的差异均有统计学意义（P＜0.008），其中气囊扩张法损伤率最高，倒入法最低。 结论 倒入法是4种方法中成功率较高且损伤小的一种方法。
ObjectiveTo summarize the research progress of ureteral injury in oblique lumbar interbody fusion (OLIF).MethodsThe literature about incidence, clinical manifestations, diagnosis, and treatment of ureteral injury complications in OLIF was reviewed.ResultsOLIF surgery poses a risk of ureteral injury because its surgical approach is anatomically adjacent to the left ureter. Ureteral injuries in OLIF are often insidious and have no specific clinical manifestations. CT urography is a common diagnostic method. The treatment of ureteral injury depends on a variety of factors such as the time of diagnosis, the location and degree of injury, and the treatment methods range from endoscopic treatment to replacement reconstruction.ConclusionSurgeons should pay attention not to damage the ureter and find the abnormality in time during OLIF. High vigilance of abnormalities is conducive to the early diagnosis of ureteral injury. Furthermore, it is important to be familiar with ureter anatomy and gentle operation to prevent ureteral injury.
