Summary
Robotic partial nephrectomy (RPN) with intracorporeal ice slush provides feasible renal hypothermia. This simplified technique is reproducible and allows real-time temperature monitoring during surgery.
Area of Science:
- Urology
- Surgical Innovation
- Nephrology
Background:
- Robotic partial nephrectomy (RPN) is a standard treatment for renal masses.
- Maintaining renal function during RPN is crucial, often involving hypothermia.
- Intracorporeal cooling methods require efficient and safe delivery.
Purpose of the Study:
- To describe a novel technique for intracorporeal renal cooling using ice slush during RPN.
- To evaluate the feasibility and safety of this cooling method.
- To assess real-time renal parenchymal temperature monitoring during the procedure.
Main Methods:
- Eleven patients undergoing RPN for solid renal masses were included.
- A simplified technique for introducing ice slush intracorporeally was employed.
- Renal parenchymal temperature was monitored in real-time using a needle probe.
Main Results:
- The technique achieved a median renal parenchymal temperature of 17.05°C.
- Median cold ischemia time was 27.17 minutes.
- Good preservation of estimated glomerular filtration rate (81%) was observed with no major complications.
Conclusions:
- Intracorporeal ice slush cooling is a technically feasible and reproducible method for RPN.
- Real-time temperature monitoring aids in managing renal hypothermia.
- This simplified approach is safe and effective for renal mass treatment.
