Abstract

Purpose: To determine the appropriate regimen of antibiotic prophylaxis for the prevention of bacterial infections in patients receiving percutaneous nephrolithotomy (PCNL).
Materials and Methods: Forty patients, who planned to undergo PCNL from October 2015 to August 2017, were assigned randomly into two groups. Patients in the single-dose group (n=20) were administered an intravenous single dose of 2 g ceftriaxone 30 minutes before PCNL, whereas those in the three-days regimen group (n=20) were administered a preoperative intravenous single dose of 2 g ceftriaxone and an additional postoperative oral cefpodoxime proxetil (100 mg twice a day) for three days. The incidences of infectious complications in the two groups, such as pyrexia, systemic inflammatory response syndrome (SIRS), and sepsis, were compared.
Results: Fever (axillary temperature >38.0°C) did not develop in any of the patients in the single-dose group but developed in one patient (5.0%) in the three-day regimen group due to pneumonia (p=0.3). SIRS developed in a total of eight patients (20.0%), four patients from each group. None of the patients in either group developed sepsis after PCNL.
Conclusions: The three-day prophylactic antibiotic regimen did not demonstrate better efficacy for the prevention of bacterial infections in patients with PCNL compared to the single-dose prophylactic antibiotic regimen.
