Are postoperative antibiotics necessary after artificial urinary sphincter insertion?

Area of Science:

• Urology
• Infectious Diseases
• Medical Device Technology

Background:

• Postoperative antibiotic use after artificial urinary sphincter (AUS) insertion is common practice.
• Concerns exist regarding antibiotic resistance and overuse.
• Evidence is lacking on the necessity of routine postoperative antibiotics for AUS procedures.

Purpose of the Study:

• To investigate the association between postoperative antibiotic use and the risk of device explantation due to infection or erosion after AUS insertion.
• To compare outcomes in patients who received postoperative antibiotics versus those who did not, considering risk factors.

Main Methods:

• Retrospective review of 155 patients undergoing AUS insertion between 2013 and 2017.
• Patients were stratified into three groups based on risk factors for complications and postoperative antibiotic status.
• Outcomes including device explantation for infection or erosion were analyzed.

Main Results:

• No significant difference in explantation rates for device infection (0-6%) or cuff erosion (2-8%) was observed across the three groups.
• Median follow-up was comparable among the groups, ranging from 8.3 to 12.7 months.
• The presence of risk factors did not correlate with increased explantation rates in the absence of postoperative antibiotics.

Conclusions:

• Routine postoperative antibiotic administration may not be necessary for all patients undergoing artificial urinary sphincter insertion.
• The findings suggest a potential to reduce antibiotic exposure without compromising device integrity.
• A randomized controlled trial is recommended to definitively assess the benefits and risks of postoperative antibiotics in this patient population.
