Primary vaginal stone in an 11-year-old recumbent girl.

Primary vaginal stones are extremely rare, particularly in young women. We describe the occurrence of a primary vaginal calculus in a severely retarded 11-year-old girl who was not diagnosed until she was examined using computerized tomography. We postulate that the calculus was formed as a consequence of urinary contamination of the vagina in association with incontinence and prolonged maintenance in a recumbent posture. Copyright 2000 S.
