Surgical repair of urethrovaginal fistula: a practical guide
A urethrovaginal fistula is an abnormal connection between the urethra and vagina. It can allow urine to pass continuously through the vagina, often with recurrent urinary infections, vaginal discharge, skin irritation or pain during sex. Injury during childbirth is a leading cause worldwide, although pelvic surgery, trauma and radiation-related tissue damage can also create a fistula. The condition can be physically and emotionally demanding, often affecting confidence, relationships and daily work.
Surgical repair is usually the definitive treatment for a significant defect, but no single operation suits every patient. Success depends on the fistula’s site and size, tissue quality, previous attempts, infection, and whether bladder-neck support or continence was already impaired. The aim is a closed urinary tract, a urethra that heals without narrowing and stable bladder control. A successful closure can still leave stress incontinence that needs further assessment.
Most people are reviewed by a urologist or urogynaecologist with gynaecologists and pelvic-floor specialists. Fever, severe pelvic pain, reduced urine output or rapidly worsening discharge needs prompt medical review, while stable leakage can be assessed through a planned pathway. This guide explains diagnosis, common operations, recovery and practical steps for obtaining care in Australia.
Causes, symptoms and diagnostic assessment
History and examination help identify the cause and exclude other causes of vaginal leakage. Doctors may use cystoscopy to inspect the urethra and bladder, urethrocystoscopy to view the fistula from below, and ultrasound, CT urography or urodynamics when anatomy is uncertain. Vaginal swabs may identify infection, and biopsy may be considered for an unusual, non-obstetric defect. A vesicovaginal fistula and ureteric injury must be distinguished because their management differs.
Fistulas are described by location, length, number and tissue condition. A distal urethral defect may be approached vaginally, whereas a larger defect near the bladder neck or one surrounded by heavy scarring may need abdominal or combined access. Radiation injury, prior repair attempts and active infection raise recurrence risk. These details shape both the operation and the likely continence outcome.
Patients can prepare questions using online health information, but such material cannot establish the diagnosis or replace examination. Ask the specialist whether the repair is intended to treat leakage alone or also to address bladder support, and request a clear explanation of the expected recovery pathway.
Preparing for reconstructive surgery
Before repair, the team generally treats infection, anaemia, malnutrition, diabetes and other issues that impair healing. Smoking cessation is important, and vaginal oestrogen may be advised after menopause when clinically suitable because it can improve tissue quality. After an obstetric injury, repair is commonly postponed until infection, swelling and tissue damage settle; an indwelling catheter may be used selectively after radiation injury.
Consent should cover recurrence, urethral stricture, urinary leakage, pain with intercourse, vaginal anatomy and possible later continence surgery. Some patients also discuss fertility, menopause and sexual wellbeing. A pelvic-floor physiotherapist can begin rehabilitation around the operation, although manual therapy and dilators must be timed to healing rather than started indiscriminately.
Any additional urinary disorder needs separate assessment. For example, BPH combination therapy addresses male bladder-neck enlargement and is not a substitute for fistula-specific management. In a patient with leakage, the team should still establish whether the fluid is urine from the urethra, a ureteric leak or another cause.
Selecting the repair approach
No route is automatically best. The surgeon chooses one that exposes the fistula fully while minimising injury and preserving blood supply. Experience with complex pelvic reconstruction matters as much as the name of the operation.
| Repair route | Common indications | Potential benefits | Important limitations |
|---|---|---|---|
| Transvaginal | Small, distal fistulas with healthy tissue | Direct access, usually less abdominal pain and shorter recovery | Limited exposure, possible vaginal shortening or pain with intercourse |
| Transabdominal | Larger or proximal defects, including some bladder-neck fistulas | Wide exposure and easier reconstruction of several structures | Longer recovery and added bowel or abdominal risks |
| Transperineal or combined | Complex, recurrent or radiation-related defects | Greater flexibility and access to the urethra and bladder neck | More tissue injury, specialist expertise and careful drain management needed |
| Flap-assisted repair | Recurrent, scarred or poorly vascularised defects | Adds healthy, vascularised tissue between healing surfaces | Requires a donor site and may involve a longer operation |
Many straightforward cases can be completed through a transvaginal route under regional or general anaesthesia. Larger or proximal defects, circumferential injury and radiation-related scarring may require transabdominal, transperineal or combined access. A tissue flap can reinforce the repair, although complex surgery usually needs a longer hospital stay and coordinated catheter, drain and follow-up care.
Techniques that improve durability
In a simple repair, the surgeon removes non-viable tissue, mobilises the urethra and bladder, and closes the defect in layers without tension. Healthy tissue is preferred over scar, and excessive tissue removal is avoided because it can narrow the urethra or shorten the vagina. The bladder is then tested for leaks, and a catheter may be kept in place to drain urine while the new closure heals.
For recurrent, radiation-related or larger defects, the surgeon may place healthy tissue between the urethra and vagina. A Martius flap uses fat from the labium, a gracilis muscle flap brings vascularised muscle from the thigh, and an omental flap uses abdominal fat. These are examples of interposition flaps that can support healing and reduce recurrence. Synthetic mesh is not routine because infection, erosion and fibrosis can complicate recovery.
Extreme injuries may need referral to a tertiary centre. Operations can be staged, and urinary diversion is occasionally considered for a urethra that cannot be reconstructed safely. Cancer or recurrent infection must be treated rather than assumed to explain the fistula. Histology from any suspicious tissue is reviewed so that underlying disease is not missed.
Recovery, continence and follow-up
After surgery, the catheter drains urine while the repair settles, and clinicians monitor output, pain, wound healing and signs of infection. Some patients also have a suprapubic catheter or drain. Instructions should state who to call if the catheter blocks, drainage becomes bloody, fever develops or pelvic pain worsens. Follow-up may include vaginal examination, cystoscopy, a cough stress test or urodynamics.
Recovery is more than wound healing. Vaginal intercourse, tampons and penetrating sexual activity are usually avoided until the surgeon confirms that the repair has united. Pelvic-floor exercises and gradual mobilisation can support general recovery, while pressure on the repair, constipation and heavy lifting are managed according to the surgeon’s advice. Persistent pain or vaginal dryness may require gynaecological review rather than simply more analgesia.
Continence can vary after closure. Some patients become dry, while others leak with coughing or exercise. Urodynamics can distinguish stress incontinence from urgency or detrusor overactivity. Persistent stress leakage may be treated after healing with a midurethral sling or another continence procedure. For a patient who also has prostate cancer, the journal’s advanced prostate cancer therapy review can guide discussion of treatment-specific urinary and sexual effects, although hormone therapy itself does not repair a fistula.
Practical measures that improve outcomes
Preparation should be organised and realistic. Patients benefit from knowing which symptoms are expected, who will manage the catheter and when escalation is required. A written plan is especially helpful when follow-up occurs outside the treating hospital.
These measures support safer repair and recovery:
- Request referral to a surgeon with experience in fistula and pelvic-floor reconstruction.
- Complete infection, blood sugar, nutrition and smoking reviews before surgery.
- Keep a clear record of catheter drainage and seek urgent help for blockage, fever or severe pain.
- Arrange pelvic-floor support, interpreter services and culturally safe care, including Aboriginal health workers where requested.
- Agree on follow-up and a plan for any persistent stress incontinence.
- Discuss privacy, sexual comfort, vaginal changes, insurer cover and likely out-of-pocket costs early.
Support should be arranged early, not only after a complication. In regional and remote areas, ask whether telehealth review, local catheter care and travel support are available. Family involvement is optional and should follow the patient’s consent and preferences.
Accessing specialist care in Australia
In Australia, care is usually coordinated through a general practitioner (GP), a public hospital or a private specialist. Melbourne, Sydney and Brisbane have major urogynaecology and reconstructive urology services, while some complex cases are referred interstate. Waiting times and travel can be significant, so early referral matters even when surgery is not immediate. Patients can request a female urologist or urogynaecologist and an interpreter, and these preferences should be documented.
Medicare provides rebates for eligible specialist consultations and public hospital treatment, but private surgery can involve insurer-funded and self-funded components, with possible gap payments. Clarify the estimated hospital, surgeon, assistant, anaesthetist, investigation and continence-product costs before admission. Check insurer waiting periods and pre-existing-condition terms, and ask whether hospital choice affects access to pelvic-floor physiotherapy and follow-up.
If you have continuous or recurrent vaginal leakage, arrange a GP appointment and explain that a urethral or vaginal defect is suspected. Bring previous operation notes, imaging and medication lists, and ask for an urgent pathway if fever, severe pain or urinary retention is present. The GP can request urology and gynaecology review, while the specialist team can tailor surgical repair, recovery support and a continence plan to the individual.
