    Abstract:
    Prophylactic ureteric stenting in renal transplantation reduces major urological complications; however, morbidity is related to the indwelling duration of a stent. We aimed to determine the optimal duration for stents in this clinical setting. Patients (aged 2-75 years) from six UK hospitals who were undergoing renal transplantation were recruited and randomly assigned to either early stent removal at 5 days (without cystoscopy) or late removal at 6 weeks after transplantation (with cystoscopy). The primary outcome was a composite of stent-related complications defined as pain, visible hematuria, migration, fragmentation, and urinary tract infections (UTIs) within 3 mo of transplantation. Between May 2010 and Nov 2013, we randomly assigned 227 participants, with 205 included in the final analysis of the primary outcome. Stent-related complications were significantly higher in the late versus early stent removal groups (36 of 126 [28.6%] vs. 6 of 79 [7.6%]; p < 0.001). The majority of stent complications consisted of UTIs, with an incidence of 31 of 126 (24.6%) in the late group compared with 6 of 79 (7.6%) in the early group (p = 0.004). We found early stent removal on day 5 significantly reduced stent-related complications and improved quality of life in the first 3 mo after transplantation (ISRCTN09184595).
