Effect of nicardipine on renal function following robot-assisted laparoscopic radical prostatectomy in patients with pre-existing renal insufficiency

摘要

OBJECTIVE: To investigate the renoprotective effect of nicardipine in patients with pre-existing renal insufficiency undergoing robot-assisted laparoscopic radical prostatectomy (RALRP). METHODS: Men with preoperative renal insufficiency (estimated glomerular filtration rate [eGFR] <60 ml/min per 1.73 m(2)) were enrolled and randomized to receive either 0.5 µg/kg per min nicardipine continuous infusion (nicardipine group) or normal saline (control group) during RALRP. Renal function was determined by eGFR and serum creatinine concentration. RESULTS: Serum creatinine levels on postoperative days (POD) 1 and 3 were significantly lower than baseline values in the nicardipine group (n = 50). In the control group (n = 50), eGFR was significantly higher on POD 3 than baseline, and was significantly higher than baseline on POD 1 and 3 in the nicardipine group. The change in eGFR from baseline to POD 1 was significantly higher in the nicardipine group than the control group. CONCLUSION: Continuous infusion of nicardipine during RALRP improved postoperative renal function on POD 1 in patients with pre-existing renal insufficiency.
