Giant Vesicovaginal Calculi Secondary to a Forgotten Vaginal Tampon Complicated With Vesicovaginal Fistula: A Rare Case Report

Vesicovaginal fistulas in developing countries are mostly of obstetric origin. The etiology involving calcified vaginal foreign bodies is rare. We report an exceptional case of a giant vesicovaginal stone in a 67-year-old woman, secondary to a forgotten and calcified vaginal tampon, complicated by a vesicovaginal fistula. Treatment consisted of stone removal and fistula repair during the same surgical procedure as part of a health campaign for the treatment of urogenital fistulas. The postoperative course was uneventful; the patient was dry upon catheter removal. This observation shows the importance of clinical diagnosis in situations of insufficient technical facilities and the feasibility of treatment in a single surgical procedure.
