ABSTRACT

Vaginal stones are rare. We can classify them as primary or secondary, depending on the presence or the absencse of a foreign body nidus. Various cases can led to stone formation. Most of them developed in women with a vesicovaginal or urethrovaginal fistula, as well as in patients with congenital anomalies of the genitourinary tract, previous pelvic radiotherapy, neuropathic bladder and other different causes of vaginal outlet obstruction. Secondary vaginal stones, formed around foreign bodies, are not so frequent. Radiological examination and urethro-vaginoscopy make easy the right diagnosis. Sometimes the stone may be fragmented by lithotripsy before the extraction. The associated etiology should be treated concomitantly in order to prevent recurrence. We report a case of primary vaginal stone associated with an urethrovaginal fistula in a 25 years old women and a review of the related literature.
