Long-term efficacy of ureteral dilation for transplant ureteral stenosis.

Transluminal ureteral dilation was performed in 11 renal allograft recipients with transplant ureteral obstruction. Success was achieved in 5 patients (45 per cent) with a followup of 12 to 29 months (mean 19.6 months). All failures have been evident within 12 months of dilation. We conclude that ureteral dilation can provide long-term success in renal allograft recipients. However, continued close long-term monitoring of the anatomical and functional result is mandatory for patients treated in this manner.
