Contemporary Microbial Profile of Artificial Urinary Sphincter Erosions

OBJECTIVE: There is a dearth of data for artificial urinary sphincter (AUS) erosions after the introduction of InhibiZone-coated devices in 2008. We aim to identify common organisms associated with non-infected and infected AUS device erosions. MATERIALS AND METHODS: We reviewed our prospectively collected, institutionally approved quality improvement database of AUS implantations, removals, or revisions performed our facility. Devices implanted after 2008 that subsequently eroded were included for review. Erosion was confirmed cystoscopically in all cases. Urine cultures and intraoperative cultures (tissue, aspirate, or swab) were reviewed. Descriptive analyses of clinical and culture data were performed. RESULTS: (11%). Positive intraoperative cultures isolated more gram-negative organisms (47%) than gram-positive organisms (38%). CONCLUSION: InhibiZone-coated AUS devices erosions were associated with a wide variety of organisms, including gram-positive, gram-negative, and fungal species. This can help guide modern anti-microbial prophylaxis practices and empiric treatment pathways in the eroded patient.
