Prospective comparative study of two protocols of antibiotic prophylaxis in percutaneous nephrolithotomy.
2013
Abstract Background and Purpose: Percutaneous nephrolithotomy (PCNL) is considered to be a clean-contaminated surgical procedure, and all patients are recommended to receive antibiotic prophylaxis before the operation to prevent septic events. The aim of the present study is to prospectively compare two different protocols of antibiotic prophylaxis in PCNL. Patients and Methods: Seventy-three patients with preoperative sterile urine were randomized into single-dose or short-course antibiotic prophylaxis groups. Patients in the first group (n=36) were given only a single dose of ceftriaxone during induction of anesthesia, while the second group (n=37) were given an oral third-generation cephalosporin after ceftriaxone until nephrostomy catheter withdrawal. For each patient, urine samples that were taken during initial access into the collecting system, as well as some stone fragments, were sent for culture and sensitivity analysis. Moreover, urine samples of the patients were cultured preceding nephrostomy...
