Purpose: 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.
Materials and 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.
