We describe a new technique for internal drainage of lymphocele following renal transplantation performed by laparoscopy. After induction of the pneumoperitoneum, using the cautery hook, a wide opening in the lymphocele peritoneal wall has been performed allowing the lymph flow to enter the peritoneal cavity. A portion of the omentum has been pushed inside the lymphocele cavity and fixed to the parietal peritoneum in order to avoid closure of the peritoneal window. A postoperative CT scan control has shown the complete disappearance of the fluid collection. Internal drainage of lymphocele performed by laparoscopy allows a radical treatment with minimal trauma for the patient and has therefore potential advantages over the other current procedures.
