Primary vaginal calculus in a patient with meningomyelocele.

The development of a rare vaginal calculus in a 12-year-old girl with meningomyelocele since birth is attributed to urinary stasis resulting from prolonged urinary incontinence, decubiti of long duration and almost complete lack of medical or rehabilitation care. After surgical removal of the calculus without complications, a series of elective orthopedic procedures has been gradually undertaken and a program of intermittent catheterization has been started.
