*Purpose: Expanding metal ureteral stent has been proven to be effective in the treatment of ureteral stenosis (US). However, its application in US after kidney transplantation (KT) is rarely reported. Here we described our experience of self-expanding metal ureteral stent in the management of recalcitrant US after KT.
*Methods: We conducted a retrospective review of all patients with diagnosis of US after KT received treatment of Allium® ureteral stent at the West China Hospital, from January 1st, 2019 to May 31st, 2020.This study was approved by Ethics Approval Committee of West China Hospital.
*Results: 15 patients with US diagnosis received self-expanding metal ureteral stent placement procedures and followed up for 8 months (rang,2-20). The ureteral stricture segments were located in the distal and the ureterovesical anastomosis site for all 15 cases, and the length was 2.2±1.0 cm. The procedure time for the stent placement was 71.4±29.3 minutes. After the procedure, two patients had fever, and no one developed urinary sepsis. Immediate ultrasonography did not reveal any further hydronephrosis and all patients had stable renal function. One month after the procedure, three patients had stent migration, with one returned to normal after reinserting, and the other two migrated again one month later and have to remove the stent. All other patients had stent in-situ at the last follow up. The overall success rate was 86.7%.
*Conclusions: This study indicated that self-expanding metal ureteral stent is an effective treatment for US following KT
