Percutaneous nephrolithotomy for renal calculi complicating with ureteropelvic junction stenosis in 56 patients

目的分析并探讨经皮肾镜治疗肾结石合并肾盂输尿管连接部狭窄的临床治疗效果。方法对我院2008年5月至2011年5月期间采用经皮肾镜技术治疗肾结石合并肾盂输尿管连接部狭窄共计56例患者的临床资料进行回顾性分析，对其治疗效果进行总结和探讨。结果所有患者均一期完成手术，手术时间为60～110min，术中出血量50～150ml，无严重并发症发生。术后随访发现患者症状均有不同程度减轻，患者患肾积水均较前减轻。结论采用经皮肾镜术治疗肾结石疗效显著、安全性好、恢复快、并发症发生率低、结石清除率高，是治疗肾结石合并肾盂输尿管连接部狭窄的一线疗法。

Objective To analyze and explore the clinical efficacy of percutaneous nephrolithotomy for renal calculi complicating with ureteropelvicjunction stenosis. Methods The clinical data of 56 patients with renal calculi complicating with ureteropelvicjunction stenosis undergoing percutaneous nephrolithotomy from our hospital from May 2008 to May 2011 retrospectively analyzed. The clinical efficacy was summarized and discussed. Results all patients＇ operations were completed in one stage operation with 60- 110 minutes operation time. Bleeding volume during operation was 50-150 ml. No serious complications occurred. Postoperative follow-up revealed patients symptoms had different degrees of ease and patients with hydronephrosis were relieved. Conclusions Percutaneous nephrolithotomy for renal calculi is significantly efficacious, safe, fast recovery and has low complication rate and high stone-free rate. It＇s a first- line therapy for renal calculi complicating with ureteropelvicjunction stenosis.
