[Prevention of infectious and inflammatory complications after percutaneous nephrolithotomy]

Given the increase in antibiotic resistance of uropathogens, one of the urgent problems is a development of optimal antimicrobial prophylaxis for surgical interventions, as well as an adequate regimen of antibiotic therapy after percutaneous nephrolithotomy (PCNL).

to determine an effective perioperative antimicrobial prophylaxis for PCNL in patients with kidney stones.

A total of 90 patients with staghorn or multiple large kidney stones who underwent PCNL were included in the study. Before PCNL, urine culture was performed in all patients in order to determine the sensitivity not only to antibiotics, but also to bacteriophages. In addition, urine was taken for additional microbiological studies after the puncture of the collecting system, as well as on the 3rd and 7th day after PCNL. All patients were divided into three groups of 30 patients depending on the regimen of perioperative prophylaxis. In group 1, patients were prescribed ciprofloxacin 1000 mg i.v. intraoperatively, then 1000 mg i.v. q.d. for 3-5 days. In the group 2, patients received one dose of cefotaxime + sulbactam (1.0 g + 0.5 g) 2 hours before PCNL i.m. In the group 3, a polyvalent pyobacteriophage purified was given orally 1 hour before PCNL in a dose of 40 ml and the same dose was used t.i.d. for 3-5 days postoperatively.

In all three groups of patients, the following infectious complications were evaluated: acute pyelonephritis, systemic inflammatory response syndrome (SIRS) and urosepsis. There were no serious infectious and inflammatory complications in the early postoperative period among all patients. SIRS developed on days 1-3 after PCNL in 26.6%, 20% and 20% of patients in group 1, 2 and 3, respectively. However, by days 4-7 after PCNL, there was normalization of blood cells count (leukocytes, neutrophil band cells), temperature and general condition.

Different regimens of antimicrobial prophylaxis for PCNL have the same efficiency. The development of SIRS on days 1-3 after PCNL is correlated not only with the antimicrobial agents used and the route of their administration (intravenously, intramuscularly and orally). Most likely, the development of SIRS is more associated with surgical trauma.
