Urine leak after nephron-sparing surgery is a difficult and morbid situation that may delay recovery and necessitate additional hospitalization and intervention. The use of cryoablation to treat a 34-year-old woman with persistent urine leak after robotic-assisted partial nephrectomy is described. Surgery was performed to treat ureteral duplication that resulted in recurrent urinary tract infections and back pain. Cryoablation was performed with computed tomography guidance, targeting urine extravasation observed after the administration of intravenous contrast medium. Imaging performed after ablation confirmed resolution of the urine leak; renal function was preserved.
