作者对14例肾移植术后发生输尿管狭窄患者进行了经皮输尿管扩张术,成功11例(79%),复发3例(21%)。扩张成功的11例随访12～61个月,平均29个月。本组女性5例,男性9例,年龄17～48岁。发生狭窄的部位分别为膀胱再造口处、发生过输尿管尿外渗与输尿管尿外渗并发脓肿处、输尿管肾盂成形术吻合口处,以及输尿管其它部位。作者认为,移植术后6个月内查出的输尿管狭窄,扩张效果较好。但在扩张成功的11例中,有4例其狭窄在移植术后6～13年方才得到诊断。12例(86%)采取了
The authors performed percutaneous ureteral dilatation in 14 patients with ureteral stricture following renal transplantation, 11 (79%) successful and 3 (21%) relapsed. Eleven patients with successful follow-up of 12 to 61 months, an average of 29 months. The group of female 5 cases, 9 males, aged 17 to 48 years. Stenosis occurred in the re-stoma, respectively, occurred in the ureter and ureteral extravasation of urethral abscess, ureteroplasty anastomosis, and other parts of the ureter. The authors believe that ureter stenosis detected within 6 months after transplantation, dilatation better. However, in 11 cases of successful expansion, 4 cases of stenosis in 6 to 13 years after transplantation had just been diagnosed. Twelve cases (86%) were taken
