The artificial urinary sphincter and urinary catheterization: what every physician should know and do to avoid serious complications.

The artificial urinary sphincter is an effective tool for urinary incontinence that is being seen in more patients because of the increased numbers of artificial sphincters being implanted and increased patient lifespan. If a patient with an artificial urinary sphincter is catheterized without manipulation of the artificial sphincter, serious irreversible complications may result. All of these complications are easily preventable by physician and nurse awareness of the artificial urinary sphincter and knowledge of how it works. Therefore, it is important for every physician to be knowledgeable about the artificial urinary sphincter.
