What is Female Urethral Stricture?
Female urethral stricture is a narrowing of the urethra — the short tube that carries urine from the bladder out of the body. The narrowing is caused by scar tissue within or surrounding the urethral wall and restricts the flow of urine.
Although urethral stricture is far more common in men, it does occur in women and is considerably under-recognised. Because women have a much shorter urethra, the condition is often missed or misdiagnosed as overactive bladder, recurrent urinary tract infection (UTI), non-specific voiding dysfunction or urethral syndrome (pain). As a result, many women experience symptoms for years before the correct diagnosis is reached.
Typical symptoms include a slow or weak urinary stream, hesitancy and straining, a sensation of incomplete emptying, recurrent UTIs and urethral pain. With an experienced specialist team, accurate diagnosis is straightforward, and modern reconstructive techniques — particularly buccal mucosal graft (BMG) urethroplasty — offer excellent long-term results. Honorary Associate Professor Ockrim is one of the few surgeons internationally with extensive experience of female urethroplasty and female urethral reconstruction.
An under-recognised cause of voiding difficulty in women
If you have had years of slow stream, straining, or recurrent UTIs that have been attributed to overactive bladder or "just one of those things," it is worth being assessed by a urologist with experience in female reconstruction. The correct diagnosis often makes effective treatment possible.
Symptoms of Female Urethral Stricture
Symptoms can develop gradually over months or years and are often mistakenly attributed to other conditions. The most common features include:
Slow or weak urinary stream
A reduced flow of urine that may have come on gradually. Many women only realise the change when comparing with how they used to pass urine.
Straining to pass urine
Needing to push or bear down in order to empty the bladder. This is not normal and often indicates an outflow obstruction.
Post-void dribbling
Leakage of small amounts of urine immediately after finishing urinating, often because urine has pooled behind the narrowing.
Hesitancy
Difficulty starting the flow of urine, sometimes with a delay of several seconds even when the bladder feels full.
Frequency and urgency
Many women experience an urgent need to pass urine and frequent toilet visits. These symptoms are often misattributed to overactive bladder when in fact they are caused by an obstructed bladder.
Sensation of incomplete emptying
A persistent feeling that the bladder has not fully emptied after passing urine, often associated with a measurable post-void residual on scanning.
Urinary retention
In severe or long-standing cases, the bladder may become unable to empty at all. Acute retention is painful and requires urgent catheterisation.
Recurrent urinary tract infections
Repeated UTIs are common because incomplete emptying allows bacteria to multiply in residual urine. This is often the first clue that something more is going on.
Dysuria (painful voiding)
Urethral strictures and associated inflammation can cause passing urine to be painful.
Often mistaken for overactive bladder
Because frequency, urgency, and recurrent UTIs are common, female urethral stricture is frequently labelled as overactive bladder or chronic UTI. If symptoms have not responded to standard treatments, a flow study and cystoscopy should be considered.
Causes of Female Urethral Stricture
Identifying the underlying cause helps to plan the most appropriate reconstruction and reduce the risk of recurrence. The most common causes include:
Idiopathic
In a large proportion of women, no clear cause is identified. This is the most common scenario and does not affect the chances of successful treatment.
Iatrogenic (medical or surgical)
Previous urethral or vaginal intervention including urethral dilatation, traumatic catheterisation, mid-urethral sling surgery, urethral diverticulum surgery or other pelvic procedures can cause scarring of the urethra.
Pelvic radiotherapy
Radiotherapy for cervical, uterine, vaginal, or other pelvic cancers can cause delayed tissue damage and urethral scarring, sometimes years after treatment.
Trauma (including obstetric)
Pelvic fracture, straddle injury, or difficult vaginal delivery can damage the urethra. Long or obstructed labour is a rare cause in the UK but a major cause worldwide.
Lichen sclerosus
A chronic inflammatory skin condition that can affect the vulva and urethral meatus, causing progressive scarring and narrowing.
Recurrent urethritis
Repeated inflammation or infection of the urethra can cause cumulative scarring over time.
Congenital
A small number of women have a narrowing that has been present since birth, only becoming symptomatic in adulthood.
How We Diagnose Female Urethral Stricture
Accurate diagnosis is essential, both to confirm that a stricture is present and to define its length and location so that reconstruction can be planned correctly. Our assessment typically includes:
Clinical history & uroflowmetry
A detailed history together with a urinary flow test. A characteristically low and plateau (flattened and prolonged) flow with a high post-void residual is highly suggestive of obstruction.
Video-urodynamic studies
Pressure-flow testing, combined with video fluoroscopy, is used to confirm bladder outflow obstruction, visualise the site and delineate the degree of obstruction, and distinguish from other causes of voiding dysfunction.
Cystourethroscopy
Direct visualisation of the urethra and bladder using a fine flexible camera. This confirms the presence, location, and length of the stricture and assesses the bladder for any secondary changes.
Pelvic MRI
High-resolution imaging to map exact position and the length of the stricture and assess for any associated urethral pathology such as a urethral diverticulum or other anatomical abnormality.
Treatments We Offer
The right treatment depends on the length, location, and history of the stricture, and on whether it is recurrent. At London Urology Specialists, we provide the full range of treatments for female urethral stricture in-house.
Urethral Dilatation
Temporary measureGentle stretching of the narrowed segment using graduated dilators. Dilatation can provide useful short-term relief and can be helpful diagnostically, but the stricture commonly recurs over weeks or months. Repeated dilatations may cause further scarring, so it is generally regarded as a temporary measure rather than a definitive treatment.
Endoscopic Urethrotomy
Short, simple stricturesA small incision is made in the scar tissue through a fine telescope, opening up the narrowed segment. Best suited to short, simple, first-presentation strictures, with a more limited role in long-segment or recurrent disease.
Intermittent Self-Catheterisation (ISC)
Maintenance therapyIn selected women, gentle self-catheterisation a few times each week helps to keep the urethra open after dilatation or urethrotomy, delaying or avoiding the need for further surgery. It is taught with full support from our specialist nurses.
Surgery – Female Urethroplasty
Definitive reconstructionFor long term resolution surgery is indicated. The aim is to incise the stricture and then place a vascularised graft into the scar to keep it patent. There are a number of different techniques to achieve this goal. The main two techniques are:
Vaginal flap urethroplasty
Vaginal flap urethroplasty involves using the patient's anterior vaginal wall tissue as a flap to widen the narrowed urethra, restoring a healthy channel for urine flow.
Buccal Mucosal Graft (BMG) Urethroplasty
A small piece of the lining from the inside of the cheek (buccal mucosa) is used as a graft to widen the narrowed segment of urethra. Buccal mucosa is ideal because it is durable, well-suited to a wet environment, and the donor site heals quickly with no visible scar. The graft can be placed either as a:
- ›Ventral onlay — graft placed on the underside of the urethra supported by a Martius fatty flap from the labia
- ›Dorsal onlay — graft placed on the upper surface of the urethra under the pubic bone
The urethroplasty techniques restore the normal calibre and resolve the symptoms of urethral strictures without the need for repeated dilatations or self catheterisation. Honorary Associate Professor Ockrim's published success rates are over 85% over a 5–10 year period.

About Buccal Mucosal Graft (BMG) Urethroplasty
Surgery replaces the cycle of repeated dilatations with a single, durable reconstruction. The evidence of the best technique for female urethroplasty is still evolving but the most recent review suggests that for most patients buccal mucosal graft urethroplasty may have the best durability for women with recurrent and / or complex female urethral stricture.
Why buccal mucosa?
Tissue from inside the cheek is robust, used to a moist environment, takes well to the underlying blood supply where grafted, and heals quickly. The mouth donor site closes itself within around 2 weeks and leaves no visible scar.
Ventral or dorsal onlay
The graft can be placed either on the upper (dorsal) or lower (ventral) surface of the urethra as an onlay patch supported by vascularised (Martius) fat taken from the labia. The choice depends on the position of the stricture and surgeon preference, and both approaches give excellent results in experienced hands.
High success rate
Reported long-term success rates from specialist centres are over 85% in the University College London Hospital series (and 80–90% in other series), meaning that most women regain a normal urinary stream and avoid the need for further dilatation.
Recovery & Outcomes
A urinary catheter is left in place for 3 to 4 weeks after surgery to allow the graft to take and the repair to heal without tension. Most women return home within 1–2 days of the procedure.
The catheter is removed after a check urethrogram has confirmed that the repair has healed. The mouth donor site is typically tender for a few days and heals fully within around 2 weeks.
Most women return to light activity within a week or two and to most normal activities after the catheter is removed. Follow-up usually includes uroflowmetry to confirm the urethra has remained open. Reported success rates for female BMG urethroplasty are in the order of 80–90%, with most women experiencing significant and lasting improvement in their flow and symptoms.

Key Takeaways
If you have a long-standing slow stream, straining, or repeated UTIs that have not responded to standard treatment, female urethral stricture should be considered. A urology assessment with uroflowmetry, urodynamics and cystoscopy will usually give a clear answer, and modern reconstructive techniques offer durable results in most women.

Frequently Asked Questions
Yes. Although urethral stricture is far more common in men, women can also develop a narrowing of the urethra. Female urethral stricture is under-recognised and often misdiagnosed as overactive bladder or recurrent urinary tract infection. It can cause a slow stream, straining to pass urine, incomplete emptying, and recurrent UTIs, and should be assessed by a specialist urologist with experience in female reconstructive urology. Honorary Associate Professor Ockrim is one of the few reconstructive urologists with a specialist interest in female urethral stricture management.
Typical symptoms include a slow or weak urinary stream, hesitancy and straining to pass urine, a sensation of incomplete bladder emptying, post-void dribbling, and recurrent urinary tract infections. Some women experience frequency and urgency that have been misattributed to overactive bladder, and in severe cases urinary retention can occur.
Urethral dilatation can provide short-term relief, but the stricture often recurs over weeks or months. It is best regarded as a temporary measure rather than a definitive treatment, and repeated dilatations can themselves cause further scarring. For recurrent or significant female urethral strictures, formal reconstructive surgery — most commonly buccal mucosal graft (BMG) urethroplasty — gives much more durable results.
Buccal mucosal graft (BMG) urethroplasty is the gold-standard surgical reconstruction for female urethral stricture. A small piece of tissue is taken from inside the cheek (the buccal mucosa) and used as a graft to widen the narrowed segment of urethra. It can be placed on the upper (dorsal) or lower (ventral) surface of the urethra as an onlay. Buccal mucosa is ideal because it is durable, well-suited to a wet environment, and the donor site inside the mouth heals quickly with no visible scar. Reported success rates are over 85%. Honorary Associate Professor Ockrim is one of the few reconstructive urologists with a specialist interest in female buccal mucosal graft urethroplasty.
A urinary catheter is usually left in place for 2 to 3 weeks after surgery to allow the repair to heal. The mouth typically heals within around 2 weeks. Most women return to light activity within a week or two and to most normal activities within 4 to 6 weeks. Follow-up usually includes uroflowmetry and cystoscopy to confirm the urethra has remained open, with reported success rates of 80–90% following BMG urethroplasty.
