Management of lymphoceles after renal transplant: case report of a novel percutaneous image-guided treatment technique.

A 65-year-old African American man with end-stage renal disease underwent renal transplantation and developed a perigraft lymphocele with an associated progressive increase in serum creatinine 6 weeks after surgery, which failed to resolve with percutaneous drainage and surgical therapy. Fluoroscopic and ultrasound-guided percutaneous transperitoneal balloon fenestration with a 22-mm, 2-cm-long balloon catheter resulted in resolution of the lymphocele as shown by ultrasound at 3 and 5 months.
