输尿管镜术后双J管引流无效原因分析

目的　总结输尿管镜手术后应用双J管引流无效的原因。　方法　回顾性分析 2 0 0 0年 6月至 2 0 0 3年 3月输尿管镜手术后放置双J管引流的 3972例患者拔管前进行追踪观察。男 2 184例 ,女 1788例 ,共放置双J管 4 6 35例次 ,其中经尿道逆行放置者 3138例次 ,经皮肾造瘘口顺行放置者14 97例次。　结果　全组双J管引流无效者 115例次 ,占 2 .4 8%。常见原因有严重腔外梗阻、严重输尿管石街、严重输尿管狭窄和支架管过期留置。　结论　严格掌握输尿镜手术及双J管放置适应证和术后紧密追踪观察是减少发生输尿管镜术后双J管引流无效的关键

Analysis of failed drainage of double J ureteral stents following ureteroscopy

Objective To summarize the causes of failed drainage of double J ureteral stents following ureteroscopy. Methods From June 2000 to March 2003,the double J ureteral stents were placed for 3972 patients (2184 males and 1788 females)following ureteroscopy.The stents were placed through retrograde approach in 3138 cases,through antegrade approach in 1497 cases.The patients were followed up until the ureteral stents were retrieved. Results Of the 4635 cases,failed drainage of double J ureteral stent was found in 115 cases (2.48%).The main causes were severe extra luminal obstruction,serious steinstrasse,severe ureteral stricture and overperiod placement of ureteral stents. Conclusions Correctly identifying the indications for ureteroscopy and the placement of double J ureteral stents as well as close follow up are the keys to reduce the failure rate of drainage of double J ureteral stents following ureteroscopy.
