Artificial urinary sphincter - In rare cases, a surgeon implants an artificial urinary sphincter, a doughnut-shaped sac that circles the urethra. A fluid fills and expands the sac, which squeezes the urethra closed. By pressing a valve implanted under the skin, the artificial sphincter can be deflated. This removes pressure from the urethra, allowing urine from the bladder to pass.

Anaclitism - Diaper fetishes are sometimes mentioned as an example of anaclitism, a desire for things one was exposed to in infancy. Anaclitism is a more general term in one way, as the objects don't necessarily have to be infantile, just things that one would have been exposed to during infancy. However, it is more narrow in another way: It implies that the conditions started in infancy. While anaclitism's definition fit into Freud's theories well, it hasn't been developed or supported empirically.
