输尿管软镜碎石术后肾包膜下血肿的危险因素分析

输尿管软镜；肾包膜下血肿；结石

摘要:

目的：探讨输尿管软镜碎石术后继发肾包膜下血肿的危险因素。方法：回顾性分析2007年1月至2017年12月1 705例行输尿管软镜碎石术后出现肾包膜下血肿的11例患者临床资料，其中男3例，女8例。应用ｔ检验、卡方检验及多因素logistic回归分析输尿管软镜术后发生肾包膜下血肿的独立危险因素。结果：将患者分为实验组和对照组。实验组21例均经术后泌尿系B超或CT检查确诊肾包膜下血肿。女性、尿培养阳性、肾积水、术中是否手工灌洗在2组患者间存在显著性差异（P<0.05），同时多因素logistic分析显示，尿培养阳性、肾积水、术中是否手工灌洗是行输尿管软镜碎石术后发生肾包膜下血肿的独立危险因素。结论：女性、尿路感染、肾积水、术中是否手工灌洗是输尿管软镜碎石术后继发肾包膜下血肿的危险因素。

Abstract:

Objective：To investigate the risk factors of renal subcapsular hematoma after Ho：YAG laser lithotripter through flexible ureteroscope. Methods：Eleven the records of the 1 705 patients undergoing ureteroscopy and Holium laser lithotripsy for renal calculi from 2007 Janunary to 2017 December in our hospital were reviewed retrospectively. The enrolled patients including 3 males and 8 females. T test，chi-square test and multi-factor logistic regression were used to analyzed the risk factors. Results：Patients were divided into two group. All 11 patients were diagnosed by CT scan or ultrasound. Gender，urinary tract infection，hydronephrosis and manual irrigation in the operation were significant differentt in two groups. The multi-factor logistic regression analysis also showed urinary tract infection，hydronephrosis and manual irrigation in the operation were independent risk factors for renal subcapsular hematoma after Ho：YAG laser lithotripter through flexible ureteroscope. Conclusion：Urinary tract infection，hydronephrosis and manual irrigation in the operation are independent risk factors for renal subcapsular hematoma after Ho：YAG laser lithotripter throughflexible ureteroscope.
