Large primary vaginal stone secondary to vesico-vaginal fistula in a 63-year-old woman

Vaginal stones are incredibly rare. Primary stones are seen in cases of urethro-vaginal or vesico-vaginal fistula. Secondary stones are more common and caused by deposition of calcium over foreign bodies introduced into the vagina. This report presents a case of a 63-year-old woman with vesico-vaginal fistula incidentally diagnosed to have large vaginal stone. The patient was referred to our practice suffering from urine dribbling through the vagina for a long time secondary to vesico-vaginal fistula. She has had repetitive unsuccessful attempts of surgical repair. MRI examination of the pelvis was requested aiming to locate the site of the fistula
