title: Duration of urinary leakage after open non-stented dismembered pyeloplasty in pediatric patients.
abstract: OBJECTIVE
  We aimed to determine the duration and associated complications of postoperative urinary leakage in pediatric patients undergoing open, non-stented dismembered pyeloplasty for ureteropelvic junction obstruction.
  
  
  METHODS
  A retrospective review of 100 patients who underwent an open non-stented dismembered pyeloplasty between 2003 and 2008 was performed. Duration of urinary leakage and postoperative complications were tabulated. Patients were considered to have a dry anastomosis if the Penrose drain was removed within one week of surgery.
  
  
  RESULTS
  Duration of leakage ranged from 0 to 27 days. 86% had Penrose drain removal within 7 days of surgery and were considered dry.14 patients demonstrated a persistent urinary leakage (PUL) ranging from 7 to 27 days. Complications of any type were significantly more likely in the group with prolonged drainage (p = .0126). UTI and obstruction were not significantly more likely to occur in patients with PUL (p = .0931 and p = .2616 respectively). Only one patient with PUL required placement of a ureteral stent.
  
  
  CONCLUSIONS
  We demonstrate that stentless dismembered pyeloplasty is feasible with a low rate of urinary drainage beyond one week. The character and quality of the slightly increased complications in those that demonstrated PUL were not great and not bothersome enough to warrant routine stenting.
