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. 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. 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.
尿道填充剂常用于治疗压力性尿失禁（SUI）。关于这些药物的长期数据很少，关于迁移或尿道侵蚀的报道也很少。我们描述了一个独特的病例，一名女性在因持续性SUI注射尿道填充剂聚二甲基硅氧烷3年后接受了尿道中段吊带术。她随后反复出现的尿路感染导致发现尿道填充剂的膀胱颈侵蚀并伴有钙化。当接受尿道填充剂的患者出现刺激性排尿症状时，必须考虑侵蚀的可能性。此外，对于先前接受过尿道填充剂注射的SUI患者的最终治疗方法知之甚少。
