Ureteropelvic junction obstruction (UPJO) is a common cause of symptomatic ureteral obstruction. The aim of this study is to assess the outcome of laparoscopic pyeloplasty in patients with UPJO.
Medical reports of 47 UPJO patients treated with laparoscopic pyeloplasty were retrospectively analysed. All patients were recruited from our center in the period 2004-2011.
We evaluated 47 patients. Mean age was 36 years and mean hospital stay 3.6 days. 42 (79%) of the patients had pain and 46 (98%) were diagnosed with hydronephrosis. 19 patients (40%) had a renal function below 40% of the affected kidney and 49% had impaired renal scan drainage. Postoperative significant improvement in pain score and renal scan drainage was found in 92% and 47% of the patients, respectively. Improvement of renal function > 10% was found in 11 patients (23%); the function remained stable in 31 patients (66%) and deteriorated > 10% in 5 patients (11%). We found no correlation between sex or age and the outcome.
Laparoscopic pyeloplasty for UPJO leads to relief of pain and preserved or improved renal function in the majority of the patients. Overall laparoscopic pyeloplasty is an efficient treatment for UPJO.
肾盂输尿管连接处梗阻（UPJO）是有症状的输尿管梗阻的常见原因。本研究旨在评估腹腔镜肾盂成形术治疗UPJO患者的疗效。
回顾性分析47例接受腹腔镜肾盂成形术治疗的UPJO患者的病历报告。所有患者均于2004年至2011年期间从本中心招募。
我们评估了47例患者。平均年龄为36岁，平均住院时间为3.6天。42例（79%）患者有疼痛，46例（98%）被诊断为肾积水。19例（40%）患者患侧肾功能低于40%，49%患者肾扫描引流受损。分别有92%和47%的患者术后疼痛评分和肾扫描引流有显著改善。11例（23%）患者肾功能改善>10%；31例（66%）患者肾功能保持稳定，5例（11%）患者肾功能恶化>10%。我们发现性别或年龄与疗效之间无相关性。
腹腔镜肾盂成形术治疗UPJO可使大多数患者疼痛缓解，肾功能得以保留或改善。总体而言，腹腔镜肾盂成形术是治疗UPJO的有效方法。
