输尿管软镜治疗肾下盏结石的临床研究

Flexible ureteroscope in the treatment of lower calyceal renal calculi

摘要:

目的：探讨输尿管软镜钬激光碎石术治疗肾下盏结石的有效性和安全性。方法：采用输尿管软镜钬激光碎石术治疗肾下盏结石42例。其中原发性肾下盏结石36例，继发性肾下盏结石6例。结果：除1例因输尿管下段狭窄入镜失败，其余41例成功入镜并寻及结石，结石一次性清除率为82.92%（35/41）。有1例术后出血，无感染性休克、输尿管撕脱等并发症。结论：输尿管软镜联合钬激光治疗肾下盏结石疗效可靠、安全，并可能成为长径小于2 cm的肾下盏结石（尤其是非梗阻性肾下盏结石）的一线治疗选择。

Abstract:

Objective：To investigate the efficacy of flexible ureteroscope in the treatment of lower calyceal renal calculi. Methods：To－tally 42 patients with lower calyceal renal calculi were treated with Holmium laser lithotripsy through flexible ureteroscope including 36 cases of primary lower calyceal calculi and 6 cases of secondary calculi. Results：All cases were successful operated except one case due to lower urethral stricture. The primary clearance rate was 82.92%（35/41）. There was no serious complication except blood－ing in one case. Conclusion：Holmium laser lithotripsy through flexible ureteroscope is a safe and effective treatment for lower calyceal renal calculi. And it may become the first treatment option for lower calyceal renal calculi with diameter less than 2 cm，especially for lower calyceal renal calculi without obstruction.
