Abstract
Objective: Artificial urinary sphincter (AUS) is the mainstay surgical treatment for refractory male stress urinary incontinence. The urinary tract of incontinent men is frequently colonized by bacteria, but the correlation between colonization and postoperative device infection is unclear. The objective of this study is to evaluate the impact of preoperative urinalysis (UA) or urine culture (UCx) on postoperative AUS infection.
Methods: A retrospective cohort study was performed, evaluating all patients who underwent AUS placement or revision at a single institution between January 2016 and March 2025. Demographic data, preoperative urine test results, and infection rates were reviewed. A positive UCx was defined as >100K CFU of bacterial growth and postoperative infection was defined as explant at any time post-operatively for infection. Preoperative tested (UA vs. UCx) vs. non-tested cohorts were compared using Chi-square/Fischer Exact test, t-test, and logistic regression.
Results: A total of 743 AUS surgeries were performed by one of three fellowship trained surgeons during the time period evaluated. The overall AUS infection rate was 1.6% (12/743). Median age was 71, median BMI was 28.6, 50.7% of patients had a history of radiation, 33.5% of cases were revisions, and 27.5% patients had diabetes. Preoperative UA was obtained in 25.0% (186/743), UCx in 14.5% (108/743), and 70.4% (523/743) had no preoperative urine testing. There was no difference in the rate of postoperative AUS infection between these three groups (1.8% vs. 0% vs. 1.9%, p=0.993). None of the 108 patients with a UCx developed a postoperative infection despite 34 testing positive, only 20 of whom were treated with preoperative antibiotics.
Conclusion: Postoperative AUS infections are rare, and do not appear to be impacted by preoperative urinalysis and/or urine culture, calling into question the need for routine preoperative urine testing prior to AUS placement.
