Background And Purpose: Many authors who report outcomes of laparoscopic cryoablation for renal tumors comment that real-time intracorporeal ultrasonographic monitoring of the ice-ball formation is imperative. In our experience, ultrasonographic monitoring of the ice-ball formation necessitates significantly more mobilization of the kidney, and the images are difficult to interpret because of artifact and the cryoablation effect on the tissue. We report our intermediate outcomes for laparoscopic cryoablation without real-time ultrasonographic monitoring of the ice ball.
