Rendezvous technique following thermal ureteric injury after radiofrequency ablation in a solitary kidney.

Percutaneous radiofrequency (RF) ablation is a promising treatment for solid renal tumors in selected patients. Nontarget thermal damage is a known risk of the procedure. The authors describe a case of a patient who underwent RF ablation of a lower pole renal lesion and subsequently developed a ureteric stricture secondary to thermal injury. Successful management of the ureteric stricture required a rendezvous procedure. This report illustrates the potential complication of ureteric stricture formation after a RF ablation procedure and the management challenges posed by such thermal injuries.
