Repetitive ureteral stenting for management of transplant graft ureteral obstruction.

PURPOSE To review the use of repetitive stenting in the management of patients with ureteral obstruction after renal transplantation, with an emphasis on technique and functional graft outcome. MATERIALS AND METHODS Five adult renal allograft recipients with ureteral obstruction were managed with repetitive ureteral stenting. Their hospital records, office notes, and operative reports were reviewed. RESULTS All patients were successfully managed with retrograde ureteral stenting. They underwent an average of 8.8 stent changes over a mean 34.5 month follow up. No decline in renal function was observed. CONCLUSIONS Repetitive stenting is a viable treatment option for select patients with renal allograft ureteral obstruction.
