Vesico-Uterovaginal fistula

Vesico-utero-vaginal fistula (f vesicouterofacialis; synonyms: vaginal-vesical fistula, Fallot - steam fistula; “dry lips”, “cadaveric point”) is a pathological anastomosis between the vaginal cavity and the bladder.

A fistula is formed as a result of destruction of the mucous membrane of the bladder after an inflammatory process, birth trauma or mechanical damage during diagnostic studies, when, during surgery, jaws of an instrument are inserted into the bladder cavity to find the fallopian tube from which urine flows, which is typical for ectopic pregnancy and other diseases . Due to the rupture of the hyaloid tissue, a defect in the mucous membrane of the bladder is formed. The swollen area bleeds easily. In case of traumatic lesions, a fistula occurs as a result of gross displacement of the uterus or amniotic presentation, when the walls of the bladder are injured by instruments or by pulling the umbilical cord. Also, during sexual intercourse, bladder rupture or fistulous subitubar early ectopia of the prostate gland can occur. If the mucous membrane of the bladder has signs of a tumor, then a periurethral ulcer or ulcerated oleocele can lead to the formation of a fistula. May be due to invasion of small cell carcinoma or epithelial hyperplasia, as the bladder wall may degenerate. Destruction of the bladder is carried out by excision of the fistula tract or performing a cystostomy with the installation of a silicone drainage catheter.

**Clinical picture**. Bladder catheterization often causes genital hyperemia. However, with prolonged existence, vaginal fistulas can gradually heal, and its edges begin to scar. Therefore, ureterovesical fistula
