Percutaneous balloon dilatation for transplant ureteral strictures

Journal Article:

Abstract

We report 10 kidney allografted patients treated for 11 ureteral strictures with standard endourlogic balloon catheter dilatation and internal stenting between August 1979 and December 1991. They have been followed until 2 to 140 months (mean 42). We compared and analyzed the 6 successful strictures (54%) and 5 unsuccessful strictures. There was no statistically significant difference of demographic, clinical and radiologic interventional techniques between two groups. But there was slightly higher success rate in abruptly narrowed shorter fibrotic strictures in ureteroneocystomy sites than smoothly taped longer ones in other sites of the ureter. Longterm stenting by the transplantation team with cystoscopic removal of internal ureteral stents by urologists resulted in 3 cases of stent occlusion, encrustation or fracture. Exact early diagnosis of ureteral stricture with continued close follow up and proper radiologic interventional procedure with optimal stenting period may increase the success rate and still provide an alternative to surgery.
