[Laparoscopic fenestration of lymphocele after renal transplantation: report of two cases].

Lymphocele after renal transplantation is a complication that often requires surgical treatment. We performed laparoscopic drainage for the postoperative lymphocele in two renal transplantation patients. The patients were suffering from perineal discomfort and urinary frequency due to the lymphocele after the renal transplantation. Percutaneous catheter drainages and injections of tissue sclerosing agents such as povidone-iodine solution and tetracycline were not effective. Then fenestration of the lymphocele by laparoscopic technique was done. This procedure made the lymphatic fluid free from the lymphocele in the retroperitoneal space to the peritoneal cavity following creation of a peritoneal window. There were no apparent complications. The patients were free from symptoms and had no relapse 10 months after the operation. We report the procedure and the results of the laparoscopic fenestration.
