(1) Ureterovaginal fistula: Is there leakage communicating with vagina after ureteral injury? Mainly caused by cervical cancer surgery, some will heal naturally, and some will do surgery to move the ureter to the bladder?
(2) Bladder-vagina fistula: There is an abnormal passage between bladder and vagina, which makes urine leak into vagina. Even if there is no intention to urinate, urine will continue to flow out? Based on the location of the fistula? Size and location, can a certain amount of urine be accumulated in the bladder? Most of the reasons are that the delivery time is too long, so that the bladder and vaginal wall between the fetal head and pelvis are compressed for too long and necrosis occurs, and the necrotic tissue falls off to form a fistula?
With the development of obstetrics, vesicovaginal fistula rarely occurs? In addition, obstetric forceps and other gynecological operations may sometimes cause vesicovaginal fistula? Long-term placement of pessary or cancer radiotherapy in vagina can also cause fistula? Fistula caused by malignant tumor is difficult to cure. Small fistula caused by some other reasons can be healed naturally or repaired surgically, but if the first operation fails, it will be more difficult to repair it later?
(3) Rectal-vaginal fistula: Is it caused by abnormal communication between rectum and posterior vaginal wall? In severe cases, the stool is incontinent, and in light cases, the air leaks? When the perineum is torn three times, if the suture is not good, will rectovaginal fistula occur? Like bladder and vagina, it can also happen after cancer cell infection or radiotherapy? Small fistula can heal naturally, should the fistula caused by postpartum be operated? Cancer-related rectovaginal fistula is difficult to cure. Someone wants to make an artificial anus on the abdominal wall, that is, to make another outlet for feces?
(4) Urethral-vaginal fistula: The urethra descends along the anterior vaginal wall? Forward, if the injury communicates with the vagina, it will form a urethrovaginal fistula. Although there will be no urinary incontinence, urine will leak into the vagina when urinating? Most urethrovaginal fistulas are caused during childbirth?
