Robot-assisted partial nephrectomy with intracorporeal renal hypothermia using ice slush: step-by-step technique and matched comparison with warm ischaemia.

We conclude that RAPN with intracorporeal renal hypothermia using ice slush is technically feasible and may improve postoperative renal function in the short term. Our technique for intracorporeal hypotheramia is cost-effective, simple and highly reproducible.
