Inflatable artificial urinary sphincters provide excellent voluntary continence. Eighty-four consecutive patients underwent implantation of artificial urinary sphincters for intractable urinary incontinence; 33 patients had 58 episodes of sphincter malfunction, and eight patients had eight complications involving a functional prosthetic sphincter. Retrospective analysis was performed to determine the value of plain radiography of the pelvis in patients with sphincter malfunction or complication. The cause of malfunction in the majority of patients was a system leak and subsequent loss of hydraulic fluid (31 occurrences; 53%). Plain radiography permitted correct identification of all instances of fluid leakage in patients with opacified prostheses. Plain radiographs were of no value in examining patients with nonopacified prostheses or the complications of cuff erosion or wound infection. Due to the low cost and noninvasive nature of plain radiography of the pelvis, we conclude that it should be used as the initial diagnostic modality in patients with previously opacified but currently dysfunctional artificial urinary sphincters.
可充气式人工尿道括约肌能实现极佳的自主控尿。连续84例患者因顽固性尿失禁接受了人工尿道括约肌植入术；33例患者出现了58次括约肌功能障碍，8例患者出现了8次涉及功能性假体括约肌的并发症。进行回顾性分析以确定骨盆平片对括约肌功能障碍或并发症患者的价值。大多数患者功能障碍的原因是系统泄漏及随后液压流体流失（31例；53%）。骨盆平片能够正确识别假体显影患者所有的液体泄漏情况。骨盆平片对未显影假体患者或袖带侵蚀、伤口感染并发症的检查没有价值。鉴于骨盆平片成本低且无创，我们得出结论，对于先前假体显影但目前功能失调的人工尿道括约肌患者，应将其作为初始诊断方式。
