A short course of antimicrobial therapy for asymptomatic bacteriuria is safe and effective before urologic procedures
Introduction: In the presence of asymptomatic bacteriuria (ASB) before the urological procedure, the duration of antimicrobial treatment is controversial. This study aims to evaluate whether a short course of antimicrobial therapy is safe and effective in cases with ASB before urological procedures.
Methodology: We retrospectively reviewed adult patients who had ASB before undergoing several urological procedures between 2011 and 2019. The patients received a single dose of an appropriate parenteral antibiotic, determined by antimicrobial sensitivity testing, 30 to 60 minutes before the urological procedure. If a urinary catheter was placed post-procedure, a second dose was given.
Results: A total of 293 patients who had ASB before undergoing several urological procedures were included in the study. The total number of procedures was 328. Female/male ratio was 92 (31.4%)/201 (68.6%). The mean age was 63.7 ± 14.9 years. The most common isolated microorganisms were Escherichia coli (155 [47%]), Klebsiella pneumoniae (38 [11.6%]), and Pseudomonas aeruginosa (28 [8.5%]). The most common antimicrobial used was ertapenem. A second dose antimicrobial was given for 290 procedures due to a urinary catheter after a urological procedure. The mean hospitalization time was 3.97 ± 3.42 days. None of the patients developed infectious complications.
Conclusions: This study has demonstrated that a single dose of parenteral antimicrobial drug administered 30-60 minutes before the urologic procedures and a second dose in the presence of a post-procedure catheter, was adequate to prevent post-procedure septicemia and urinary tract infection.
