肾移植应用输尿管支架管内引流与外引流的疗效比较

目的；比较肾移植常规应用输尿管支架管内引流与外引流以降低尿路并发症的疗效。方法：肾移植506例，第一阶段共238例采用输尿管支架管外引流，第二阶段共112例随机分成两组，外引流组58例，内引流组54例，进行前瞻性研究，第三阶段共156例均采用内引流。比较各阶段尿路并发症发生率。结果：三个阶段尿路并发症发生率分别是10．10％（24／238），7．14％（8／112）和0．64％（1．156），总体尿路并发症发生率在外引流和内引流患者分别是10．50％（31／296）和0．95％（2／210）。结论：常规应用双J管内引流优于外引流。

Comparison of the effect of ureteral stents of extracorporeal and intracorporal drainage in renal transplantation

Purpose:To compare the effect of ureteral stents of extracorporal and intracorporal drainage for decreasing urological complications in renal transplantation. Method:Our 3-phase study included 506 consecutive renal transplantations from December 1993 to March 2000. In phase l.all 238 patients received ureteral stents of extra-corporal drainage. In phase 2,58 and 54 cases received ureteral stents of extracorporal and intracorporal drainage respectively. In phase 3, all the 156 cases received Double-J stents. We reviewed urological complications at various phases. Result: In phase 1, the urological complication rate was 10. 10%, which decreased to 7. 14% in phase 2. In phase 3 there was only 0. 64%. Overall urological complication rate in extracorporal and intracorporal drainage cases was 10.50% (31 of 296) and 0.95% (2 of 210) respectively. Conclusion; Routine Double-J stenting could prevent urological complications, which was superior to ureteral stenting of extracorporal drainage.
