Ten ureteral strictures that developed in nine patients after renal transplantation were managed with balloon catheter dilation and placement of a ureteral stent. Four strictures were successfully dilated (40%), with a follow-up of 15-42 months (mean, 29 months). Comparison of these cases with the six cases of unsuccessfully dilated strictures failed to show any substantial differences between the groups with respect to demographics, stricture characteristics, or radiologic management techniques. However, strictures that developed at the ureteroneocystostomy site responded favorably more often (three of four strictures) to balloon catheter dilation than did strictures in other locations. The authors' experience is not as favorable as that of others who have managed renal transplant-related ureteral strictures in a similar manner. Nonetheless, their experience reinforces the efficacy of balloon catheter dilation of ureteral strictures that develop after renal transplantation as an effective alternative to surgical revision in a substantial percentage of patients.
9例肾移植患者出现了10处输尿管狭窄，采用球囊导管扩张术并放置输尿管支架进行治疗。4处狭窄成功扩张（40%），随访时间为15 - 42个月（平均29个月）。将这些病例与6例扩张失败的狭窄病例进行比较，结果显示两组在人口统计学、狭窄特征或放射学处理技术方面均无显著差异。然而，输尿管膀胱吻合口处出现的狭窄对球囊导管扩张术的反应更频繁（4处狭窄中有3处），比其他部位的狭窄更有效。作者的经验不如其他以类似方式处理肾移植相关输尿管狭窄的人那么理想。尽管如此，他们的经验强化了肾移植后出现的输尿管狭窄采用球囊导管扩张术的有效性，在相当比例的患者中，这是手术修复的有效替代方法。
