Intraperitoneal Tenckhoff Catheter for the Treatment of Recurrent Lymphoceles After Kidney Transplantation: Our Early Experience

Lymphoceles may occur as frequently as 16% of the time after kidney transplantation, becoming clinically evident between 18 and 180 days after surgery. The management of lymphoceles is unclear. Percutaneous needle aspiration and external drainage are associated with high recurrence and complications. Surgical intraperitoneal marsupialization of lymphocele is considered the treatment of choice, but requires hospital admission, general anesthesia, and sometimes extensive surgical dissection. We discuss our experience in the treatment of recurrent symptomatic lymphocele intraperitoneally drained using a Tenckhoff catheter in 7 consecutive patients. Clinical manifestations became evident between 26 and 90 days after transplantation. The diagnosis was obtained with abdominal ultrasound in all cases; mean lymphocele diameter was 14 ± 6 cm. After percutaneous drainage, performed to differentiate urinoma/lymphocele and to rule out infections, the lymphocele recurred within 1 month. Thereafter, we decided to treat recurrent lymphatic collection using a Tenckhoff catheter. The lymphocele was located during the operative procedure using a sterile 3.5-MHz ultrasound probe. With the patient under local anesthesia, we performed 2 vertical 1-cm incisions to the lymphocele and peritoneum, respectively. The Tenckoff catheter was first positioned into the lymphocele and the tunneled inside the peritoneal cavity. One cuff of the Tenckhoff was fixed to the fascia to avoid possible delocalization. The patients were discharged the same day. The catheter was removed 6 months later with no evidence of lymphocele recurrence.
