Urethral Diverticulum in Women: Symptoms, Causes & UK Management

A urethral diverticulum is a relatively uncommon condition where a small 'pocket' or out-pouching develops in the wall of the urethra—the tube that carries urine from the bladder out of the body. In the UK, this condition primarily affects women, usually between the ages of 30 and 60. Because the pocket is located so close to the vaginal wall, it can often be felt as a lump or swelling.

Urine can become trapped within this pocket, leading to a range of uncomfortable symptoms. Because these symptoms often overlap with more common conditions like cystitis or vaginal thrush, a urethral diverticulum is frequently misdiagnosed for months or even years. Understanding the specific 'classic' symptoms is key to receiving the correct specialist care from a urologist.

Medical professionals often refer to the 'three Ds' when identifying a urethral diverticulum: Dysuria (painful urination), Dyspareunia (pain during sexual intercourse), and Dribbling (post-void leakage).

• Recurrent UTIs: Because urine sits and stagnates in the diverticulum, bacteria can thrive, leading to frequent infections that seem to return shortly after finishing antibiotics.
• Vaginal Pressure or Lumps: Many women report a feeling of fullness in the vagina or a palpable lump on the anterior (front) vaginal wall.
• Post-void Dribbling: This is a highly characteristic symptom where urine leaks out shortly after you have finished using the toilet, caused by the pocket slowly emptying itself.
• Painful Intercourse: The pressure on the diverticulum during sex can cause significant localised pain.
• Haematuria: Occasionally, blood may be present in the urine due to inflammation within the pouch.

While some diverticula may be present from birth (congenital), the majority are 'acquired'. The most common theory supported by NHS specialists is that the condition begins with the infection and subsequent blockage of the periurethral glands. These are tiny glands that drain into the urethra.

When these glands become blocked, they can form a small cyst. If that cyst eventually ruptures into the urethra, it leaves behind a permanent pocket. Factors that may increase the risk include chronic urinary tract infections, previous pelvic trauma, or complications from vaginal childbirth. However, in many cases, a specific cause is never fully identified.

In the UK, the diagnostic pathway typically begins with a physical examination by a GP or urologist. During a pelvic exam, a doctor may be able to feel the diverticulum or even observe 'milking' of the urethra, where pressure on the vaginal wall causes urine or pus to be expressed from the urethra.

Imaging Tests

Following a clinical suspicion, NICE-aligned pathways usually recommend imaging to confirm the size and location of the pocket. Common tests include:

• MRI (Magnetic Resonance Imaging): This is considered the gold standard for diagnosis as it provides detailed images of the soft tissues.
• Transvaginal Ultrasound: A quicker, non-invasive way to visualise the urethral wall.
• Urethroscopy: A specialist may use a thin camera to look inside the urethra directly.

Treatment depends largely on the severity of the symptoms. If the diverticulum is small and not causing significant distress or infection, a policy of 'watchful waiting' may be adopted. However, for most women, intervention is necessary.

• Conservative Management: This may include low-dose prophylactic antibiotics to prevent recurrent UTIs and manual drainage of the pocket after urination.
• Surgical Excision (Diverticulectomy): The most common definitive treatment. A surgeon removes the pocket and repairs the urethral wall. This is typically performed through the vagina, meaning there are no external abdominal scars.
• Spence Procedure: A less common surgical option where the pocket is opened into the vagina to allow it to drain freely, though this is generally reserved for diverticula near the urethral opening.

If you are experiencing recurrent urinary symptoms that aren't clearing up with standard treatments, it may be time to speak to a GP online. An online consultation is a discreet and efficient way to discuss sensitive sexual and urinary health concerns from the comfort of your home.

While an online doctor cannot perform the physical pelvic exam required for a final diagnosis, they can review your history of recurrent UTIs, assess your symptoms, and provide a referral to a private or NHS urology specialist for further investigation. They can also provide sick notes for work if your symptoms are causing significant pelvic pain or distress. If you are currently suffering from a flare-up of urinary pain, an online GP can often prescribe targeted antibiotics to manage the immediate infection while you wait for specialist scans.
