Background: Urethral bulking agents are commonly used for the management of stress urinary incontinence (SUI). Little long-term data exist for these agents, with few reports of migration or urethral erosion. Case Presentation: We describe a unique case of a woman who received a midurethral sling 3 years after receiving an injection of the urethral bulking agent, polydimethylsiloxane, because of persistent SUI. Her subsequent recurrent urinary tract infections led to the identification of a bladder neck erosion of the urethral bulking agent with a concomitant calcification. Conclusion: When irritative voiding symptoms are experienced in patients who have received urethral bulking agents, erosion must be considered. Furthermore, little is known regarding the definitive management of SUI in patients that have previously received an injection of a urethral bulking agent.
