Vaginal fistula is the presence of an abnormal opening that connects the vagina to the bladder. This is a disease that affects a lot of patients' quality of life, so it needs to be treated early. Vaginal fistula surgery is the ideal treatment for the patient.
1. Overview of urethral-vaginal fistula
Vaginal fistula is an abnormal opening that connects the vagina to another organ such as the bladder, rectum or colon. Vaginal fistulas can be congenital or occur after an injury, surgery, infection, or radiation therapy. Symptoms of the disease are weak urine stream, partial leakage of urine into the vagina. And whatever the cause, the general principle of treatment is to close the fistula, avoid infection upstream of the urinary system, and restore quality of life.
In the case of a small urethral-vaginal fistula, the doctor will apply the methods of electrocautery, injection, bio-glue, combined with bladder drainage to help the fistula become scarred. In other cases, surgery will be required.
Before performing surgery, the doctor will check that the surrounding tissue is healthy, if no need to heal first. For patients with inflammatory bowel disease, doctors will not perform urethro-vaginal fistula surgery when symptoms flare up.
Advice for patients is to perform surgery soon when the tissues around the leak site are still soft and have not been hardened due to prolonged inflammation. From the fistula, the doctor will dissect the tissue with an area large enough to close the fistula.
