title: Urological complications in 1,223 kidney transplantations.
abstract: BACKGROUND
  Urological complications after kidney transplantation may lead to graft loss. In this study, we retrospectively reviewed urological complications in 1,223 kidney transplantations that were performed at our institution.
  
  
  METHODS
  The occurrence of urological complications such as urine leakage, ureteral obstruction and vesicoureteral reflux (VUR) according to the different way of urinary tract reconstruction, ureteroneocystostomy (U-C) and ureteroureterostomy (U-U), was studied.
  
  
  RESULTS
  Urological complications were encountered in 92 (7.5%) cases, including urine leakage (n = 43, 3.5%), ureteral obstruction (n = 35, 2.9%) and VUR (n = 14, 1.1%). 75 cases (7.9%) were in the U-C group and 17 cases (6.2%) in the U-U group. 91 recipients were successfully treated, and 1 patient lost the graft due to kidney pelvis and ureteral necrosis. There was no recipient loss due to these complications. For recipients with urological complications, the 1- and 3-year survival rates were 90 and 88% for recipients and 87 and 82% for grafts, respectively.
  
  
  CONCLUSIONS
  After U-U, the same number of overall incidences of urological complications is observed as after U-C; however, a decrease in the number of incidences of urine leakage is apparent. Therefore, U-U is a good first option with a greater success rate of resolving ureteral stenosis with endourology and no risk of VUR.
