[Bladder-uterine fistulas].

Three cases of the bladder-uterine fistulas treated within the last three years (1982-1984) have been presented. All patients underwent cesarean sections (two patients once, and the third - thrice). The patients were treated surgically. Each one has undergone hysterectomy, and the opening of the fistula into the bladder has been operated by incision of the bladder in two cases and through extracystic approach in one case. Mechanism of development, symptoms, various types, diagnosis, and therapy of the bladder-uterine fistulas have been discussed.
