从1977年开始,作者开展了肾移植后输尿管狭窄的治疗,到1991年底用经皮穿刺球囊导管扩张治疗9例共10处狭窄。结合超声和同位素扫描来研究肾移植受主的尿量减低或肾功能减退及诊断考虑有同种移植肾梗阻者(包括顺行肾造影术)。如果梗阻是由狭窄以外原因引起,则行经皮肾造口术;如果输尿管狭窄确诊,则尽可能经皮扩张狭窄的部分。9例扩张的位置是输尿管肾盂交接处1例,3
Since 1977, the author has conducted the treatment of ureteral stricture after kidney transplantation. By the end of 1991, 9 cases of 10 cases of stenosis were treated with percutaneous balloon catheter. Combined with ultrasound and isotope scans to study renal transplant recipients with reduced urine output or renal dysfunction and diagnosis of allograft renal obstruction (including antegrade nephrectomy). If the obstruction is caused by a cause other than stricture, the percutaneous nephrostomy is performed; if the ureteral stricture is confirmed, the stenosed part is percutaneous dilated as much as possible. 9 cases of expansion of the ureter is the junction of renal pelvis in 1 case, 3
