A Prospective Study of Single-Dose Antibiotic Prophylaxis in Live Donor Nephrectomy

PURPOSE To perform a prospective analysis of the clinical outcomes of prophylactic antibiotic treatment before the standard surgical modality of living donor nephrectomy (LDN) without postoperative antibiotic treatment. MATERIALS AND METHODS From November 2005 to June 2010, a total of 470 patients underwent LDN at our medical institution, and 280 of these patients were injected with 1 g cephalosporin 30 minutes before the operation. The group receiving prophylactic antibiotics was compared with a control group composed of 190 patients who received injections of 2 g cephalosporin per day for 5 days after the operation. The presence of fever, incidence of blood transfusion, and period of drainage use were compared between the two groups. RESULTS There were no significant differences in gender, age, body mass index, incidence of blood transfusion after the operation, fever over 38℃ 3 days after the operation, or period of drain insertion between the single-dose group and the control group. The follow-up was conducted for 1 month after the operation, and 1 case of surgical site infection (SSI) was observed in each group (p=0.783). CONCLUSIONS Of 280 patients in the single-dose group, 1 contracted SSI. In comparison with the control group, which was dosed with prophylactic antibiotics for 5 days after the operation, the single-dose group did not have a significantly different occurrence of SSI. We found that the incidence rate of SSI did not increase, even though prophylactic antibiotics were not used after standard and conventional open surgeries, such as video-assisted minilaparotomy surgery.
