Huge primary vaginal stone in cerebral palsy patient

Vaginal stones are rarely encountered in practice, often misdiagnosed as bladder stone on plain radiography. The clinical manifestation can be unspecific ranging from asymptomatic stones to acute onset of fever or abdominal discomfort, rendering the diagnosis challenging. They are classified into primary stones resulting from urine stasis, and more commonly secondary stones formed around a nidus. Cerebral palsy is frequently associated with urinary incontinence and leads to constant leakage of urine into the vagina. In addition, the prolonged recumbent position results in urinary stasis, thus promoting stone formation.
