LAPAROSCOPIC ULTRASOUND-GUIDED DRAINAGE OF LYMPHOCELES FOLLOWING RENAL-TRANSPLANTATION

The development of a lymphocele is an uncommon but well-documented complication of renal transplantation. In most patients, lymphoceles remain asymptomatic, and no intervention is required. In some cases, however, lymphoceles become symptomatic and cause systemic and local manifestations. Ultrasonic scanning can easily diagnose and locate the size and position of perirenal fluid collections. Many of these patients can be managed conservatively by aspiration and drainage of the lymphocele under radiologic guidance. However, if the lymphocele remains symptomatic or reaccumulates after aspiration and drainage, surgical intervention may be required. We describe two different ultrasound-guided laparoscopic techniques for drainage of a perirenal lymphocele into the peritoneal cavity. Successful drainage was accomplished in 5 patients, with 1 patient suffering an injury to the ureter of the transplant kidney. Recommendations regarding patient selection and operative technique are presented.
