In this video, Jihad Kaouk, MD, Director, Center for Robotic & Image-Guided Surgery at Cleveland Clinic’s Glickman Urological & Kidney Institute, demonstrates a novel kidney cooling technique that safely expands the time needed to reconstruct the kidney in a robotic partial nephrectomy.

“Robotic surgeons are constantly working against the clock, as prolongation of clamp time results in irreversible damage, usually after only 25 minutes,” Dr. Kaouk explains.
Dr. Kaouk’s intracorporeal technique involves introducing ice slush as a reliable method of cooling the kidney that can extend the surgical window to up to an hour if needed.
“Ice cooling the kidney intracorporeally duplicates the advantages of open surgery, helping surgeons minimize excision of adjacent kidney tissue and thereby preserving kidney function and decreasing risk of dialysis. It also removes the pressure of time during robotic partial nephrectomy,” Dr. Kaouk says. “This technique is especially attractive for patients with solitary kidneys when longer ischemic time is indicated.”
Dr. Kaouk notes that ice cooling also expands indications for robotic partial nephrectomy to larger, more complex and even multiple tumors.
