To determine whether antibiotic prophylaxis can reduce the risk of postoperative infective complications in patients undergoing percutaneous nephrolithotomy (PCNL) who have sterile preoperative urine.MEDLINE, EMBASE, Cochrane Collaboration Reviews, CMCC and CNKI were searched for RCTs comparing antibiotic prophylaxis with placebo (or blank controls) for patients undergoing PCNL with preoperative sterile urine. The search strategy was made according to the Collaborative Review Group search strategy. Data were extracted by 2 reviewers using the designed extraction form. The software RevMan 4.2 was used to review management and data analysis.A total of 9 trails, 1 placebo controlled, 3 non treatment controlled, and 5 active controlled, involving 1018 patients, met the inclusion criteria. Prophylactic antibiotic use in patients at low risk undergoing PCNL significantly decreased fever (RR = 0.71, 95% CI: 0.54-0.92, P = 0.009), bacteriuria (RR = 0.39, 95%CI: 0.23-0.67, P = 0.0006) and bacteremia incidence (RR = 0.43, 95%CI: 0.25-0.73, P = 0.002). Effective antibiotic classes included quinolone which significantly decreased bacteriuria incidence (RR = 0.31, 95%CI: 0.12-0.82, P = 0.010) and nitrofurantoin which significantly decreased fever incidence (RR = 0.38, 95%CI: 0.24-0.61, P = 0.005). Extended course significantly decreased fever incidence (RR = 0.64, 95%CI: 0.47-0.87, P = 0.004) and bacteriuria incidence (RR = 0.35, 95%CI: 0.18-0.71, P = 0.003).Prophylactic antibiotics can significantly decrease the incidence of postoperative infective complications. A significant decrease in bacteriuria incidence can be achieved with quinolones. Extended course is effective in decreasing fever, and bacteriuria incidence. |
