The effect of anesthetic technique on early postoperative renal function after donor nephrectomy: a preliminary...

General and regional anesthesia may both be used successfully in donor nephrectomy although the use of regional anesthesia is rare. We compared the remaining kidney function during general (n = 10) versus combined spinal-epidural (n = 10) anesthesia for donor surgery. Blood biochemistry data were collected preoperatively and postoperatively, while renal function was assessed by scintigraphy and urine levels of microalbumin, creatinine, Na, K, Ca and creatinine clearance rate were measured/calculated in 24-hour urine samples collected preoperatively and on postoperative day 2. There were no differences preoperatively and on postoperative day 2 with respect to glomerular filtration rate, microalbuminuria, or creatinine clearance rate (P > .05 for all). There were also no differences between the groups with respect to other scintigraphic findings preoperatively and on postoperative day 2 (P > .05 for all). The results suggest that general or combined spinal-epidural anesthesia for donor nephrectomy have similar effects on the remaining donor kidney function.
