Abstract:
Objective:To explore the safety and efficacy of renal arterial hypothermia perfusion in robot-assisted laparoscopic partial nephrectomy.Methods:The data of 11 patients with complex renal tumors admitted to our hospital from March 2020 to December 2021 were retrospectively analyzed. There were 7 males and 4 females. The patients’age was (64.64±13.56) years old.The median R. E.N.A.L. score was 8 (7, 9) points. Preoperative glomerular filtration rate (GFR) was (64.40±25.52) ml/min. All patients had a renal artery cold solution perfusion robot-assisted laparoscopic partial nephrectomy. 4℃ sodium lactate Ringer's solution was injected into the affected kidney by the catheter, which could provide the kidney a hypothermic state during the operation and protected the renal function during the long period of warm ischemia. The intraoperative data and postoperative complications were recorded. The data of postoperative renal function, routine urine test, urinary CT, preoperative and postoperative glomerular filtration rate (GFR) were analyzed.Results:The renal artery blocking time was (34.09±2.84) min during the surgery. The patients’ body temperature was (36.10±0.44) ℃. The surgical duration was (126.73±47.08) min. The intraoperative bleeding was (81.82±53.07) ml. There were no complications, such as urinary leakage, low body temperature, fever, etc. There was no significant difference between the 3-months postoperative GFR (59.06±25.67) ml/min and preoperative GFR ( P=0.636). Conclusions:For patients with complex renal tumors, renal arterial cold solution perfusion in robot-assisted laparoscopic partial nephrectomy can help obtain longer operative duration during hot ischemia, preserve renal function, and it provide a safe and feasible surgical method for patients.
