title: Diagnostics and therapy of lymphoceles after kidney transplantation.
abstract: Lymphocele incidence after kidney transplantation is as high as 18%. We retrospectively studied the therapy of 42 lymphoceles that occurred in our clinic between 1990 and 2005, focusing on possible predisposing factors for their formation and the results of several therapy variants: conservative, operative, percutaneous puncture, and laparoscopic or open marsupialization. There was no connection between lymphocele formation and the following parameters: the extent to which the iliac vessels had been prepared, the materials used for the preparation, or whether clips or ligatures were applied. Lymphoceles may originate either from the lymphatic system of the recipient or the transplanted kidney. The most sensible measures to prevent their occurrence therefore seems to be to restrict the transplant bed to the smallest permissible level with careful ligature of the lymphatic vessels in the area of the kidney hilus. Treatment for lymphoceles should start with minimally invasive measures. We use the following algorithm in our clinic: puncture to differentiate between urinoma/lymphocele and to test for bacterial infection, sclerotization (200 mg doxycyclin), and finally marsupialization if persistent. The choice of operative technique depends on the location. This algorithm resulted in a relapse rate of 9.5% during the postoperative observation period of up to 15 years.
