Bulkamid urethral bulking - London.
A 20-minute day-case injection for female stress urinary incontinence - done by a specialist urogynaecologist, in a NICE-aligned London unit, with sling and overactive-bladder pathways in the same room if Bulkamid is not the right call.
Why patients choose us
- 01
A specialist urogynaecologist, in a NICE-aligned unit
Not a general urology list. A named urogynaecologist with a high Bulkamid case volume, in a unit that meets BAUS and BSUG standards.
- 02
The right procedure for the leakage
Bulkamid is not always the answer. For urgency-predominant leakage or severe SUI we recommend Botox, PTNS or a discussion about slings before you commit.
- 03
Independent, and free
We are paid by no clinic, so the recommendation is impartial and costs you nothing.

What Bulkamid is
A non-mesh injectable, NICE-recommended for stress incontinence.
Bulkamid is a polyacrylamide hydrogel - a soft, water-based gel that is non-particulate and non-migratory. It is injected around the urethra to treat female stress urinary incontinence, and is NICE-recommended (IPG694) as an alternative to a mesh sling.
-
What it is
A 97.5% water, 2.5% cross-linked polyacrylamide hydrogel. Non-absorbable, non-particulate, non-migratory - it stays where it is placed and integrates with the surrounding tissue.
-
How it works
Three injections at the mid-urethra create small bulking cushions. The urethral walls coapt (meet in the middle) more effectively, so the urethra stays closed when abdominal pressure rises with a cough or sneeze.
-
What it treats
Female stress urinary incontinence - leakage on cough, sneeze, laugh or exercise. It does not treat urgency, overactive bladder or overflow incontinence, which need different pathways.
The journey

- 01
Before
You send us the bladder diary and history
A short, confidential form. Pad usage, urgency, prior continence surgery, prior mesh, urodynamics if you have them.
- 02
Before
We come back with a recommendation
Within one working day: whether Bulkamid fits, or whether a sling, colposuspension or overactive-bladder pathway is the better call. Indicative price. An honest read either way.
- 03
Before
We arrange the procedure
Usually within one to two weeks. Anticoagulants are reviewed with the team, a urine sample rules out infection, and pre-op instructions are sent.
- 04
On the day
Arrival at the unit
Arrival, consent and a chat with the urogynaecologist and anaesthetist. Local anaesthetic with optional light sedation.
- 05
On the day
The Bulkamid injection itself
20 to 30 minutes. Cystoscopy with a 4mm scope, three injections of 0.5 to 1mL polyacrylamide hydrogel around the mid-urethra.
- 06
On the day
Home the same day
A short recovery, a test void, written aftercare, and home within a few hours. A catheter is usually not needed.
- 07
After
Review and top-up if needed
A review at 6 weeks and again at 3 months. About 30 to 40% of patients benefit from a second injection at 3 to 5 years.
Typical end-to-end: 1–2 weeks to procedure. Review: 6 weeks. Top-up if needed: 3–5 years.
How well it works
Efficacy at 1 year, 5 years, and beyond.
Bulkamid is durable but not permanent - the honest figures on cure, improvement and repeat rate, paired with pelvic-floor physiotherapy for the best long-term outcome.
-
At 1 year
Over 70% of women are dry or significantly improved. A third are completely dry, the remainder use one pad a day or fewer for reassurance.
-
At 5 to 7 years
Around 50 to 60% of women retain a meaningful benefit. Durability is best where the initial response was strong and where pelvic-floor exercises are continued.
-
Repeat injection
About 30 to 40% of patients have a top-up injection at 3 to 5 years. The repeat is quick, well-tolerated and does not prevent future sling surgery.
Every patient is referred for supervised pelvic-floor physiotherapy after Bulkamid - the combination consistently outperforms either treatment alone.
Who benefits
When Bulkamid is the right step - and when it is not.
The patients we see most often - and the clinical signs that mean a different pathway (sling, colposuspension, Botox or PTNS) is a better fit.
-
Stress urinary incontinence, mild to moderate
Leakage on cough, sneeze, laugh or exercise, with a positive stress test and no significant urgency.
-
Wanting to avoid a mesh sling
Bulkamid is a NICE-recommended non-mesh alternative (IPG694) for women who do not want a synthetic sling.
-
Elderly or high anaesthetic risk
A 20-minute procedure under local anaesthetic suits patients where a general anaesthetic is unattractive.
-
Previous failed continence surgery
Persistent SUI after a prior sling, colposuspension or Burch procedure can often be improved with Bulkamid.
-
Post-mesh-removal stress incontinence
Recurrent SUI after mesh explantation, where a further sling is not wanted, is a common indication.
-
No significant urethral hypermobility
Urodynamics or Q-tip test showing minimal hypermobility - Bulkamid works by coaptation, not by supporting a hypermobile urethra.
-
Wanting a quick recovery
Office work the next day, driving in 24 hours, no incisions - suits patients who cannot take a fortnight off.
-
Red flag: haematuria or new-onset urgency
Blood in the urine, sudden urgency or nocturia needs a bladder work-up before any bulking - not straight to the injection list.
Procedure options
Bulkamid alongside sling, colposuspension and OAB pathways.
A quick read on the alternatives so the choice is genuinely informed. Mesh sling gives higher initial cure rates; Bulkamid gives no mesh, quick recovery, and is repeatable. Burch and Marshall-Marchetti-Krantz are rarely offered now.
-
Bulkamid (polyacrylamide hydrogel)
Non-particulate, non-migratory hydrogel. Three injections around the mid-urethra create bulking cushions that improve coaptation. NICE-recommended (IPG694) alternative to mesh.
-
Retropubic mid-urethral sling (TVT)
Polypropylene mesh tape under the mid-urethra. Around 90% dry at 2 years, but a 3 to 5% rate of chronic pain, dyspareunia or mesh exposure. Currently paused in NHS pathways.
-
Transobturator sling (TOT)
Mesh tape through the obturator foramen. Similar cure rates to TVT with a different complication profile - groin pain and dyspareunia are more common.
-
Open colposuspension (Burch)
The bladder neck is suspended to the iliopectineal ligament through a Pfannenstiel incision. Around 80% dry at 5 years, no mesh, but a 6-week recovery.
-
Laparoscopic colposuspension
Keyhole version of the Burch. Similar durability to open, quicker recovery, but a longer operating time and a steeper learning curve for the surgeon.
-
Autologous fascial sling
A strip of the patient's own rectus fascia is used as a sling. No synthetic material, high durability, but a longer operation and a laparotomy scar.
-
Botox for overactive bladder
For urgency-predominant leakage rather than SUI. Injected into the detrusor via cystoscopy. Not the right tool for pure stress incontinence.
-
Second-opinion review
A specialist review of your bladder diary, urodynamics and prior operative notes - sometimes the answer is pelvic floor physio, not another procedure.

Safety and recovery
What to expect afterwards - honestly.
Bulkamid has one of the cleanest safety profiles in continence surgery. The things worth planning are your first week of activity, the small risk of UTI, and the top-up conversation at 3 to 5 years. Bulkamid is not suitable for severe stress incontinence, mixed incontinence with detrusor overactivity, urgency-predominant leakage, an active UTI or an active vulvovaginal condition.
-
Local anaesthetic, optional sedation
Most Bulkamid is done under local with a numbing gel and a short course of sedation. General anaesthetic is available for anxious patients or on request.
-
Urinary tract infection - up to 6%
The commonest complication. A pre-procedure urine dip and a short antibiotic course reduce the risk. A clear plan and 24/7 contact matters.
-
Transient voiding difficulty
A small number of patients (2 to 5%) need a temporary catheter for 24 to 48 hours if the urethra is slightly overfilled. Settles without further intervention.
-
Injection-site pain or bruising
Mild discomfort for 24 to 48 hours, usually well controlled with paracetamol. NSAIDs are avoided in the first week to reduce bleeding risk.
-
Haematuria - short-lived
Pink urine for 24 to 48 hours is expected. Frank blood, clots or difficulty passing urine needs the unit contacted the same day.
-
No heavy lifting for 1 week
Light activity from day 1, office work day 2, driving after 24 hours. No gym, running, or lifting over 5kg for the first week.
-
Sexual activity after 2 weeks
Penetrative sex is deferred for 2 weeks to allow the injection sites to heal. Bulkamid does not affect sexual function long-term.
-
Repeat rate 30 to 40% at 3 to 5 years
The hydrogel is durable but the SUI itself can progress. A top-up injection is straightforward and does not compromise future sling surgery.
-
Red flags after discharge
Fever, severe pelvic pain, inability to pass urine, or heavy vaginal bleeding - call the unit or go to A&E the same day.

Frequently asked
Everything we get asked about Bulkamid.
Quick answers on repeat rates, mesh, insurance, mixed incontinence and getting back to sex.
-
Will I need a repeat Bulkamid injection?
About 30 to 40% of women need a top-up injection at 3 to 5 years. The hydrogel itself is stable and non-migratory, but the underlying stress incontinence can progress, particularly around the menopause. A top-up is a short, straightforward procedure and does not compromise future sling surgery if needed.
-
Is Bulkamid a mesh alternative?
Yes. Bulkamid is a polyacrylamide hydrogel, not a mesh. It contains no polypropylene and no permanent implant that can be exposed, erode or need removal. NICE recommends it (IPG694) as a first-line non-mesh option for women with stress urinary incontinence who want to avoid a synthetic sling.
-
Does private insurance cover Bulkamid?
Most major UK insurers - Bupa, AXA, Vitality, Aviva - cover Bulkamid when medically indicated for stress urinary incontinence. Pre-authorisation is usually needed, and some insurers require a trial of pelvic floor physiotherapy first. We confirm cover before booking.
-
Is Bulkamid used in children or paediatric patients?
Bulkamid is licensed for adult women with stress urinary incontinence and is not used in children. Paediatric urinary incontinence is a specialist paediatric urology pathway and needs a very different work-up.
-
What if I have mixed incontinence (stress and urgency)?
If urgency is the dominant symptom, Bulkamid alone is unlikely to help enough. The usual pathway is to treat the overactive bladder first - pelvic floor physio, anticholinergics, mirabegron, PTNS or Botox - and then consider Bulkamid for any residual stress leakage. Urodynamics before the injection helps confirm the pattern.
-
When can I have sex after Bulkamid?
Penetrative sex is deferred for 2 weeks to let the injection sites heal. Bulkamid does not affect sexual function long-term, does not distort vaginal anatomy, and, unlike a mesh sling, does not carry a long-term risk of dyspareunia from an implanted tape.
