Cryotherapy and Robotic Assisted Non Ischemic Nephron Sparring Surgery

Description

Patients with renal masses eligible to partial nephrectomy often require arterial ischemia to control or prevent blood loss during this surgical procedure. This study aims to determine the safety and efficacy of renal cryoablation at the tumor bed, as a substitute measure or technique vs total or selective arterial renal ischemia.Nephron sparring surgery has emerged as the procedure of choice for most patients with renal tumors that are \>2 cm and harbor a greater than 50% exophitic component. In order to decrease blood loss surgeons may: 1- interrupt blood flow to the kidney, completely or selectively; 2-Use diuretics such as mannitol to dehydrate the kidney; 3-Ice externally the kidney - in open procedures - to decrease metabolism during ischemia. The emergence of robotic surgery triggered a shift in the the surgical approach to partial nephrectomy and is commonly employed. A fundamental drawback of this technique is represented on the lack of cold ischemia. However, warm ischemia i
