Are antibiotics necessary during routine cystoscopic stent removal?

Area of Science:

• Urology
• Infectious Disease Prevention

Background:

• The 2008 American Urological Association (AUA) Best Practice Statement suggests antimicrobial prophylaxis is not routinely needed for cystourethroscopy unless specific manipulations occur.
• No prior studies have specifically evaluated antimicrobial prophylaxis for cystoscopic ureteral stent removal.
• This study aimed to assess infectious complication risks with and without antibiotic prophylaxis during this procedure.

Purpose of the Study:

• To determine the risk of infectious complications, specifically symptomatic urinary tract infections (UTIs), following cystoscopic ureteral stent removal.
• To compare UTI rates in patients who received antimicrobial prophylaxis versus those who did not.

Main Methods:

• A retrospective review of 70 patients undergoing cystoscopic ureteral stent removal after kidney stone treatment.
• Patients were divided into two cohorts of 35: one receiving prophylactic antibiotics, the other not.
• Outcomes assessed included demographics, stone intervention details, UTI history, comorbidities, and symptomatic UTIs within 4 weeks post-procedure.

Main Results:

• No significant demographic or clinical differences were observed between the antibiotic prophylaxis and no-prophylaxis groups.
• Two patients (6%) in the prophylaxis group developed a UTI.
• None of the patients (0%) in the no-prophylaxis group developed a UTI (P=0.15).

Conclusions:

• Antimicrobial prophylaxis at the time of cystoscopic ureteral stent removal did not demonstrate a significant benefit in preventing UTIs in this cohort.
• Prospective studies are recommended to validate these findings and further inform clinical practice regarding antibiotic use.
