Abstract Background To investigate the role of antimicrobial prophylaxis in laparoscopic nephrectomy for renal cell carcinoma. Methods We retrospectively enrolled 1000 patients who underwent laparoscopic nephrectomy from August 2019 to November 2021 in the Peking Union Medical College Hospital. Patients were divided into group without antimicrobial prophylaxis ( n = 444) and group with antimicrobial prophylaxis ( n = 556). Outcomes including 30-day postoperative infection rate, the increase rate of pre- and post-operative white blood cell counts and hospital stay were analyzed. Results The overall infection rate was 5.0% (28/556) in the group with antimicrobial prophylaxis, which was similar to 4.1% (18/444) in the group without antimicrobial prophylaxis ( P = 0.461). The increase rate of pre- and post-operative white blood cell counts was significantly lower (85.5% versus 97.0%) in the group with antimicrobial prophylaxis ( P = 0.004). The postoperative hospital stay was 5 (4, 6) days in both groups ( P = 0.483). Logistic regression analyses identified the use of antimicrobial prophylaxis had no influence on the occurrence of infection events (odds ratio = 0.797; 95% confidence interval, 0.435–1.460; P = 0.462). Hemoglobin (odds ratio = 0.430; 95% confidence interval, 0.257–0.719; P = 0.001) and partial nephrectomy (odds ratio = 2.292; 95% confidence interval, 1.724–3.046; P < 0.001) influenced the use of antimicrobial prophylaxis independently. Conclusions The use of antimicrobial prophylaxis had no impact on postoperative infection in patients receiving laparoscopic nephrectomy for renal cell carcinoma.
