title: Management of lymphoceles after renal transplantation: laparoscopic versus open drainage.
abstract: OBJECTIVE
  Laparoscopic surgery has become widely accepted for the treatment of lymphoceles following kidney transplantation. In this single center study we retrospectively reviewed our results of the surgical management of post-transplant lymphoceles, assessing indication and outcome of laparoscopic versus open drainage.
  
  
  METHODS
  The records of 60 patients who underwent surgical treatment for a symptomatic lymphocele following kidney transplantation or combined kidney/pancreas transplantation were retrospectively reviewed.
  
  
  RESULTS
  Between 1995 and 2002, 1,836 patients received a kidney transplant at the University of California San Francisco. In 60 patients (3.3%) a symptomatic lymphocele developed and either laparoscopic (20) or open drainage (40) was completed. The conversion rate from laparoscopic to open drainage was 16.5%. The most common indications for open lymphocele drainage were noninfectious wound complications (13 patients) and a high risk of vessel or ureter injury (8) due to proximity of the lymphocele to hilar structures. Additional surgery on the graft was required in 5 patients. Intraoperative blood loss was significantly lower in the laparoscopy group. Median hospital stay was 1 day in the laparoscopy group versus 4 days in the open drainage group. No perioperative complications were observed in either group. After a median followup of 38 months, 2 patients in each treatment group had a symptomatic recurrence.
  
  
  CONCLUSIONS
  Although both surgical approaches are safe and effective, laparoscopic drainage should remain the method of choice for the treatment of post-transplant lymphocele. However, open drainage should be performed in patients with wound complications and in those with a small lymphocele adjacent to vital renal structures.
