Summary

Preoperative bacteriuria affects 15.4% of patients undergoing endoscopic urologic surgery. While linked to postoperative infections, sepsis risk is primarily associated with surgery duration, not bacteriuria itself.

Area of Science:

  • Urology
  • Infectious Diseases
  • Microbiology

Background:

  • Preoperative bacteriuria is a known risk factor for postoperative infections in urologic surgery.
  • Understanding the prevalence and causative agents of preoperative bacteriuria is crucial for effective antibiotic prophylaxis.

Purpose of the Study:

  • To determine the incidence of preoperative bacteriuria in patients undergoing endoscopic urologic surgery.
  • To identify common microorganisms and their antibiotic resistance patterns.
  • To ascertain risk factors for postoperative bacteriuria and sepsis.

Main Methods:

  • A cohort of 449 patients undergoing endoscopic urologic surgery was studied.
  • Urinary samples were collected preoperatively and post-treatment for bacterial culture.

Related Experiment Videos

  • Infectious complication risk factors were analyzed, focusing on postoperative outcomes.

    • Main Results:

    • Preoperative bacteriuria was present in 15.4% of patients, associated with age, sex, prior infections, diabetes, and catheter use.
    • Escherichia coli was the most frequent pathogen, with 37.9% resistance to prophylactic antibiotics.
    • Postoperative bacteriuria occurred in 22.0% of patients, directly linked to preoperative bacteriuria.
    • Sepsis of urinary origin (2.9%) was solely associated with surgery length.

    Conclusions:

    • Preoperative bacteriuria is common in patients undergoing endoscopic surgery and contributes to postoperative bacteriuria in under 25% of cases.
    • Surgery duration is the primary risk factor for sepsis of urinary origin.
