Novel presentation of labial synechiae: two urinary streams.

Labial synechiae, also referred to as labial adhesion or labial agglutination, is a disorder of the female genitalia characterized by thin, membranous adherence of the labia minora. Typically, the fusion originates from the posterior fourchette and advances toward the clitoris. Complete labial fusion may conceal the vaginal introitus completely. Partial labial fusion is also possible and may occur near the posterior fourchette.
