ABOUT TREATMENT
Vesicovaginal Fistula (VVF) Repair
Vesicovaginal Fistula (VVF) is an abnormal connection between the urinary bladder and the vagina. This can result in continuous or involuntary leakage of urine through the vagina and may significantly affect a woman's comfort, hygiene, emotional well-being, and quality of life.
VVF can develop due to several causes, including complications following pelvic or gynecological surgery, prolonged or obstructed childbirth, pelvic trauma, radiation therapy, or certain diseases and infections. The condition requires careful evaluation to determine the location, size, and complexity of the fistula.
SYMPTOMS
Common Symptoms
Urine and laboratory tests
Pelvic examination
Dye testing
Cystoscopy to examine the bladder and fistula opening
Imaging such as CT or other specialized studies when required
CAUSES
Causes of Vesicovaginal Fistula (VVF) Repair
Pelvic or gynecological surgery — such as hysterectomy, cesarean delivery, or other pelvic procedures; this is an important cause in many settings.
Prolonged or obstructed labour — prolonged pressure from the baby's head can damage the tissues between the bladder and vagina.
Pelvic trauma — injuries to the pelvis or urinary tract can sometimes result in fistula formation.
Radiation therapy — pelvic radiation can damage tissues and, in some cases, lead to fistula formation months or years later.
Severe infections or inflammatory conditions — certain infections or chronic inflammation can damage the bladder or vaginal tissues.
Malignancy (cancer) — pelvic cancers or their treatment can occasionally cause VVF.
Previous fistula surgery — recurrence can occur after an earlier repair.
RISK FACTORS
Risk Factors
Previous pelvic or gynecological surgery — particularly procedures involving the bladder, uterus, or vagina.
Prolonged or obstructed labour — prolonged pressure can cause tissue damage between the bladder and vagina.
Previous cesarean or difficult childbirth — complications during delivery may increase the risk.
Pelvic radiation therapy — radiation can weaken tissues and impair healing.
Pelvic trauma — injuries involving the bladder, vagina, or surrounding tissues.
Pelvic cancer — cancer itself or its treatment can damage nearby tissues.
Severe pelvic infections or inflammation — these may contribute to tissue breakdown.
Previous VVF or fistula repair — a recurrent fistula may develop in some patients.
Poor tissue healing — conditions that impair healing can increase complications following injury or surgery.
DIAGNOSIS
Diagnosis
Medical History: The doctor asks about continuous urine leakage, previous pelvic surgery, childbirth, radiation therapy, trauma, and other relevant conditions.
Pelvic Examination: Examination of the vagina may help identify the fistula opening and assess surrounding tissues.
Dye Test: A colored dye may be placed in the bladder to check whether it leaks through the vagina.
Cystoscopy: A small camera is used to examine the inside of the bladder and locate the fistula.
Urine Tests: Urinalysis or urine culture may be performed to identify urinary tract infection.
Imaging Tests: Ultrasound, CT urography, MRI, or other imaging may be recommended in selected or complex cases.
Additional Urinary Tract Evaluation: The ureters and kidneys may be assessed when involvement of the upper urinary tract is suspected.
TREATMENT OPTIONS
Treatment Options
Close the abnormal connection
Restore normal urinary function
Preserve bladder and vaginal function
Prevent recurrence
Improve the patient's quality of life
BENEFITS
Benefits of Treatment
Stops or significantly reduces continuous urine leakage through the vagina.
Restores more normal bladder and urinary function.
Improves personal hygiene and reduces constant wetness.
Reduces skin irritation and discomfort caused by ongoing urine leakage.
May reduce recurrent urinary infections when the fistula is contributing to them.
Improves daily activities and social confidence by reducing the limitations caused by urinary leakage.
Supports emotional and psychological well-being by addressing the physical effects of the fistula.
Protects surrounding tissues by eliminating ongoing urine exposure.
RECOVERY
Recovery & Aftercare
Continuous urine leakage through the vagina
Urine leakage that started after pelvic or gynecological surgery
Persistent urinary leakage following childbirth
Recurrent urinary infections
Irritation, discomfort, or skin problems caused by continuous urine leakage
Urinary symptoms that persist despite initial treatment
PREVENTION
Prevention
Skilled pelvic surgery: Careful surgical technique and identification of the bladder and ureters can reduce the risk of urinary tract injury during gynecological and pelvic procedures.
Timely management of obstructed labour: Appropriate antenatal care, access to skilled obstetric services, and timely treatment of prolonged or obstructed labour can reduce childbirth-related fistulas.
Prompt treatment of pelvic injuries: Pelvic or urinary tract injuries should be evaluated and treated early.
Appropriate radiation planning: Patients receiving pelvic radiation should have careful treatment planning and follow-up for tissue-related complications.
Treat infections promptly: Appropriate diagnosis and treatment of significant pelvic or urinary infections may help prevent tissue damage.
Postoperative follow-up: New urinary leakage after pelvic surgery or childbirth should be evaluated promptly rather than ignored.
COMPLICATIONS
Possible Complications
Continuous urine leakage through the vagina
Skin irritation and soreness caused by prolonged urine exposure
Recurrent urinary tract infections (UTIs)
Unpleasant odor and hygiene difficulties

Bladder or urinary tract problems in more complex cases
Emotional and social difficulties related to persistent urine leakage
Recurrence of the fistula after surgical repair
Ureteric or bladder injury in complex cases or during repair
Urinary incontinence or altered urinary function that may persist even after successful fistula closure
