title: Urologic complications in kidney transplantation: a single-center experience.
abstract: BACKGROUND
  Urologic complications are an important cause of morbidity in kidney transplantation. To prevent this occurrence, several studies have reported the benefit of stenting. The aim of this study was to compare the efficacy of two different types of stents to protect the urinary anastomosis in kidney transplantation.
  
  
  METHODS
  We performed a retrospective analysis of 139 kidney transplant recipients who underwent ureteralneocystostomy by the Lich-Gregoire technique between January 1995 and July 2010. On the basis of the type of stent we divided transplant patients into two groups: group A (n=90), the internal-external Bracci catheter and group B (n=49), the double-J stent. The urologic complications evaluated in both groups were: urinary tract leakage, obstruction, and infections. We also recorded the duration of the postoperative hospitalization.
  
  
  RESULTS
  The incidences of urinary fistulae and ureteral strictures between the two groups were similar (around 3%). A higher incidence of urinary infections, however, was registered among group A compared with group B (46% vs 10%; P<.05). The postoperative hospitalization period was consequently longer in group A then group B (35 ± 3 vs 24 ± 2 days; P<.05).
  
  
  CONCLUSIONS
  In our series of kidney transplantations, the occurrence of urinary fistulae and ureteral strictures was not influenced by the type of stent. The use of a double-J stent, however, appeared to be associated with a significantly decreased incidence of urinary tract infections leading to shorter postoperative hospitalizations.
