Summary
Routine postoperative antibiotics are not necessary after diagnostic cystoscopy. This study found low infection rates in patients receiving no antibiotics, confirming the safety of outpatient procedures.
Area of Science:
- Urology
- Infectious Diseases
- Clinical Trials
Background:
- Urinary tract infections (UTIs) are a potential complication following urological procedures.
- Diagnostic cystoscopy is commonly performed in outpatient settings.
- The necessity of prophylactic antibiotics after cystoscopy requires evaluation.
Purpose of the Study:
- To compare the incidence of bacteriuria and symptomatic UTIs after diagnostic cystoscopy.
- To determine the efficacy of routine postoperative oral antibiotics in preventing infection.
- To assess the safety and necessity of antibiotic prophylaxis in outpatient cystoscopy.
Main Methods:
- A prospective randomized trial involving 138 patients undergoing diagnostic cystoscopy.
- Patients had preoperatively sterile urine.
- Comparison between a control group (no antibiotics) and a group receiving postoperative oral antibiotics.
Main Results:
- The overall incidence of bacteriuria was 2.2%.
- Group 1 (no antibiotics) had a 2.8% incidence of bacteriuria.
- Group 2 (antibiotics) had a 1.5% incidence of bacteriuria, with only one symptomatic infection (0.7%) overall.
Conclusions:
- Outpatient diagnostic cystoscopy is a safe procedure with a low risk of infection.
- Routine administration of postoperative oral antibiotics is not indicated following diagnostic cystoscopy.
- Current evidence suggests antibiotic prophylaxis is unnecessary for this patient population.
