Ureteral leakage after radiofrequency ablation in a renal tumor: Repair with rendezvous technique

Radiofrequency ablation (RFA) is a safe and minimally invasive procedure for the local treatment of solid renal tumors in selected patients, but sometimes complications can occur. Nontarget ureteral thermal injury is a known risk of the procedure. Herein, we report a case of a patient who underwent a simultaneous treatment of surgical sigma resection and percutaneous RFA of the inferior pole renal lesion and who developed a proximal ureteric lesion secondary to thermal injury, with urinary leakage and an abscess formation of ileo psoas muscle. This report describes a successful management of the interventional radiologist team with a rendezvous procedure of these complications after RFA procedure. © 2010 Elsevier Ireland Ltd.
