Analysis of failed drainage of double J ureteral stents following ureteroscopy / 中华泌尿外科杂志

ABSTRACT

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.
