Retrograde endopyelotomy has emerged as a minimally invasive alternative for treating ureteropelvic junction obstruction (UPJO), characterized by impaired urinary transport due to intrinsic or extrinsic factors. This narrative review evaluates the long-term outcomes of retrograde endopyelotomy, focusing on effectiveness, safety, complications, and reoperation requirements.
A systematic search of PubMed, Google Scholar, and Scopus from 1990 to March 2024 identified 29 studies comprising 1238 adult patients.
Findings indicate that retrograde endopyelotomy, predominantly performed using Holmium:YAG lasers, achieved a mean success rate of 76.9%, with variability based on the type of obstruction and intervention methods. Success was inconsistently defined across studies, ranging from symptom resolution to imaging-based criteria. Complication rates averaged 12.5%, with urinary tract infections being the most common. Hospital stays were typically brief, with most patients discharged within 1-3 days.
Retrograde endopyelotomy, has the advantage of shorter recovery times and reduced invasiveness compared to open or laparoscopic approaches. Future studies should also explore advancements in laser technology, such as Thulium Fiber Laser, to optimize outcomes.
逆行肾盂内切开术已成为治疗肾盂输尿管连接部梗阻（UPJO）的一种微创替代方法，其特征是由于内在或外在因素导致尿液输送受损。本叙述性综述评估逆行肾盂内切开术的长期疗效，重点关注有效性、安全性、并发症和再次手术需求。
对1990年至2024年3月期间的PubMed、谷歌学术和Scopus进行系统检索，确定了29项研究，共纳入1238例成年患者。
研究结果表明，逆行肾盂内切开术主要使用钬：钇铝石榴石激光进行，平均成功率为76.9%，成功率因梗阻类型和干预方法而异。各研究对成功的定义不一致，从症状缓解到基于影像学的标准不等。并发症发生率平均为12.5%，其中尿路感染最为常见。住院时间通常较短，大多数患者在1 - 3天内出院。
与开放手术或腹腔镜手术相比，逆行肾盂内切开术具有恢复时间短和侵入性小的优点。未来的研究还应探索激光技术的进展，如掺铥光纤激光，以优化治疗效果。
