INTRODUCTION: Antimicrobial prophylaxis is an important issue in positive urine culture patients undergoing endourological procedures or extracorporeal shock wave lithotripsy (ESWL). It is especially recognized in asymptomatic bacteriuria patients of alarm pathogen etiology. We designed a preliminary study to determine optimal duration of antibiotic prophylaxis in patients undergoing endourological procedures or ESWL with asymptomatic bacteriuria caused by Enterobacterales with extended spectrum beta-lactamase positive (ESBL+) type resistance.
MATERIAL AND METHODS: A total of 60 patients with confirmed ESBL+ Enterobacterales bacteriuria were admitted for endourological procedures or ESWL. The patients were randomized into two groups - a one-day (n = 33) and a three-day (n = 27) period of perioperative antibiotic prophylaxis with meropenem. In both groups on the following day after the procedure (24 hours after the procedure) and 7 days after the procedure serum inflammation markers were assessed.
RESULTS: Values of white blood count, C-reactive protein and procalcitonin prior to, 24 hours and seven days after the procedure clearly showed no statistically significant differences between groups that have received a one-day and three-day antibiotic regimen.
CONCLUSIONS: In patients with ESBL+ Enterobacterales asymptomatic bacteriuria undergoing endourological procedures or ESWL a 72-hour perioperative meropenem prophylaxis showed no superiority over a 24-hour regimen. Further studies will be carried out to establish optimal prophylaxis for specific endourological procedures and to test safety of a single dose regimen.
