Objective: To evaluate if decreasing postop abx prophylaxis affects UTI and wound infection rates in patients following urethroplasty. Methods: A retrospective review of patients who underwent urethroplasty from 9/2017 - 3/2020 by a single surgeon was performed. All patients received urine culture specific perioperative IV abx prior to urethroplasty and kept a urethral catheter for 3 weeks postop. Patients undergoing a urethroplasty from 9/2017 to 12/2018 received extended postop abx prophylaxis for 3 weeks until catheter removal (Group 1). Patients from 12/2018 to 3/2020 received abx for 3 days around catheter removal (Group 2). UTIs, abx complications, and wound infections between groups were evaluated. UTIs were defined as a positive urine culture or reported lower urinary tract symptoms/fevers treated with empiric abx. Results: 120 patients underwent urethroplasty. Group 1 consisted of 60 patients with mean age of 51.9 years and mean stricture length of 3.6 cm. Group 2 had 60 patients with mean age of 53.1 years and mean stricture length of 3.8 cm. 10 patients had UTIs after urethroplasty. There was no significant difference in UTI (6.7% vs 11.7%; P = 0.529) or wound infection rates (3.3% vs 1.7%;’ P = 1.000) between the two groups. Conclusion: Extended postoperative antibiotic prophylaxis does not appear to significantly affect UTI or wound infection rates following urethroplasty. The retrospective nature of the study has limitations, however, this is the first comparison of two different antibiotic administration protocols to our knowledge.
