Urinary fistulas refer to an abnormal connection that forms between the urinary tract and another organ, causing unintended urine leakage. These fistulas often develop after pelvic or abdominal procedures, and while they’re relatively rare, they can significantly affect your quality of life. Early detection is crucial, especially since symptoms like persistent leakage or recurrent infections can be mistaken for more common post-operative issues. Although specialized urology supplies can help manage symptoms, fistulas often require surgery.

What is a Urinary Fistula?
A urinary fistula is an abnormal, unwanted connection between part of the urinary tract, such as the bladder, ureter, or urethra, and another organ or body surface. This opening allows urine to flow where it shouldn’t, often leading to continuous or intermittent urine leakage, infections, and irritation. Depending on where the connection forms, urine may leak into the vagina, bowel, or through the skin.
Some types of urinary fistulas include:
- Vesicovaginal Fistula: An abnormal connection between the bladder and the vagina. This is one of the most common urinary fistulas and often causes continuous urine leakage through the vagina.
- Enterovesical Fistula: Another common type of urinary fistula, where there's an opening between the bladder and bowel.
- Ureterovaginal Fistula: A connection between a ureter and the vagina, typically occurring after pelvic or gynecologic surgery. Urine bypasses the bladder and leaks continuously.
- Urethrovaginal Fistula: A fistula between the urethra and the vagina, which may lead to urine leakage, difficulty controlling urination, or discomfort.
- Vesicouterine Fistula: An abnormal connection between the bladder and the uterus, sometimes associated with prior cesarean sections or uterine surgery.
- Vesicocutaneous Fistula: A connection between the bladder and the skin, often resulting from trauma, infection, or surgical complications.
- Ureterocutaneous Fistula: A rare type where a ureter connects to the skin, causing urine to drain through an opening on the body surface.
- Urethrocutaneous Fistula: A rare type that occurs when there's an opening between the urethra and perineum, often due to a congenital condition or injury.
While urinary fistulas can significantly affect quality of life, they are treatable, often through surgical repair combined with appropriate medical management.
Causes of Urinary Fistulas After Surgery
Abdominal and pelvic surgeries are the leading cause of urinary fistulas. Procedures such as hysterectomy, cesarean section, bladder repair, or colorectal surgery require operating near the bladder, ureters, and urethra, which are all delicate structures. Even with careful surgical techniques, these organs can be inadvertently injured.
- Hysterectomy: Removal of the uterus can sometimes damage the bladder or ureters because they lie very close to the uterus. Small, unnoticed injuries may eventually develop into a fistula after a hysterectomy.
- Cesarean Section: During a C-section, the bladder may be accidentally nicked or sutured, particularly in complicated deliveries or repeat surgeries.
- Bladder or Ureteral Surgeries: Operations aimed at removing tumors, stones, or repairing strictures can weaken tissue or leave small openings that develop into fistulas if healing is impaired.
- Colorectal Surgery: Surgery on the rectum or colon can involve working near the bladder or ureters, creating a risk of accidental connections forming between organs.
This can happen for one of several reasons. However, most commonly, symptoms and causes arise from:
- Tissue trauma during surgery may compromise blood flow, slowing healing.
- Scar tissue or tension on sutures can prevent proper closure.
- Infection at the surgical site can interfere with healing, increasing the risk of fistula formation.
Some other potential causes of urethral fistulas or bladder fistulas include:
- Radiation therapy
- Severe pelvic trauma
- Chronic infections
- Abscesses
- Inflammatory tissue
- Extended pressure during childbirth
- Cancer or tumor growth
Symptoms of a Urinary Fistula
While some symptoms may vary based on the location of the fistula, most of them are similar and include the following:
- Continuous or intermittent leakage of urine
- Recurrent urinary tract infections (UTIs)
- Vaginal or abnormal discharge with a urine-like odor
- Pain or discomfort in the pelvis or lower abdomen
- Skin irritation or sores if urine leaks onto the skin
- Fever or general malaise in cases of infection
If you notice any of these occurring, it's essential to see your doctor for a proper diagnosis.
How is a Urinary Fistula Diagnosed?
Diagnosing a urinary fistula typically involves a combination of patient history, physical examination, and imaging tests. Your doctor may utilize any of the following:
- Medical history and symptom review. Your doctor will ask about urine leakage, infections, pain, and recent surgeries.
- Physical examination. For fistulas involving the vagina or skin, a visual exam can sometimes identify the abnormal connection.
- Dye tests. A colored dye (like methylene blue) can be introduced into the bladder to see if it appears at the fistula site. An X-ray is then used to examine the bladder.
- Imaging tests. Ultrasound, CT scan, or MRI can show the location and size of the fistula.
- Cystoscopy. A small camera is inserted into the bladder to examine the fistula and surrounding tissue.
Treatment Options for Urinary Fistulas
While some may be able to heal on their own, most will need surgery to close the fistula and repair the natural flow of urine. For those who may heal on their own, your doctor will utilize conservative therapy, which may involve using a urinary catheter to drain the bladder or having a small stent put in place in the ureter to help urine flow from the kidneys to the bladder while the affected area heals.
However, most people need surgery to repair the fistula. Typically, the type and location of the fistula will determine the surgery that's done, so you must work with your doctor for the proper diagnosis and post-surgical care.
Open surgery is the traditional approach and involves making a larger incision to access the fistula directly. Surgeons carefully remove scar tissue and close the abnormal connection, sometimes using nearby healthy tissue to strengthen the repair. This method is often preferred for complex or recurrent fistulas. The incision for open surgery can be made in various locations depending on where the fistula repair will occur.
Minimally invasive techniques, like laparoscopic surgery, use small incisions and specialized instruments to repair the fistula. These procedures generally reduce recovery time and postoperative discomfort. Similarly, robotic-assisted surgery offers even greater precision, making it ideal for delicate repairs near the bladder or ureters. Robotic techniques often result in smaller scars and faster healing compared to traditional open surgery.
For severe or complicated cases, urinary diversion may be necessary. This involves temporarily redirecting urine through a catheter or stoma, allowing the affected tissue to heal before a final repair is performed. In select situations, small fistulas may even close on their own with continuous bladder drainage using a catheter or ureteral stent.
Long-Term Recovery and Complications
Recovery time varies depending on the type of fistula, the surgical approach, and the patient’s overall health. Minimally invasive procedures like laparoscopic or robotic-assisted surgery typically allow for faster recovery, with most patients resuming normal activities within a few weeks. Open surgery may require a more extended healing period, often several months, to ensure tissues have fully repaired. During this time, following your surgeon’s instructions and using recommended urology supplies can support healing and comfort.
Even with a successful surgery, some individuals may experience complications such as frequent urinary tract infections or a recurrent fistula. If you notice any signs of an issue, it's important to see your doctor as soon as possible.
Can You Prevent a Urinary Fistula After Surgery?
Since you don't have much control over the surgical procedure itself, you can't necessarily directly prevent a fistula. However, choosing an experienced surgeon at a reputable medical facility can help lower the likelihood that it occurs. Still, fistulas may not happen due to skill level but instead may result in issues with how the body scars or heals. Therefore, it's important to follow post-op instructions and communicate with your doctor about any potential issues.
Urinary fistulas can be challenging, but understanding them helps you to take control of your recovery. If you’re managing urinary incontinence or leakage, preparing for recovery, or simply want to feel more confident throughout the healing process, having the right support and supplies makes all the difference.
