Key facts

Infected mesh at a glance.

The essentials, in plain English. What it is, why timing matters, and how it is treated in the UK today.

  • What it is

    Bacterial or mycobacterial infection of surgical mesh, most often after hernia repair or urogynaecological mesh insertion.

  • Timing

    Early (within 30 days) is typically Staphylococcus aureus, streptococci or gram-negative organisms. Delayed (over 30 days) is biofilm-driven, often coagulase-negative staphylococci, MRSA or Mycobacterium abscessus.

  • Mesh materials

    Polypropylene, PTFE, composite and biological meshes each carry different infection profiles and salvage prospects.

  • Presentation

    Local pain, erythema, warmth, wound breakdown, discharge and fistula formation. Systemic features include fever and sepsis.

  • Urogynaecology mesh

    A separate specialist commissioned pathway following the Cumberlege Review, with transvaginal mesh withdrawn in the UK.

  • Definitive treatment

    Culture-directed antibiotics, drainage where appropriate, and mesh explantation with abdominal wall reconstruction at a specialist commissioned centre.

Why this guide matters

A specialist commissioned pathway, not a scattergun.

Mesh infection is uncommon but consequential. The three points below shape the rest of this page.

  • Timing changes everything

    Early infection is dominated by S. aureus and streptococci. Delayed infection is biofilm-driven and often needs mesh removal.

  • Imaging and microbiology matter

    CT and targeted aspiration guide antibiotic choice and surgical planning. Atypical mycobacteria are easy to miss without specialist cultures.

  • Specialist centres change outcomes

    Complex hernia and urogynaecological mesh work is centralised in the UK. Ask to be referred if your case is not straightforward.

How the diagnosis is made

From first symptoms to a clear plan.

The steps a UK surgical team and specialist commissioned centre will normally follow, in order.

  1. 01

    Assessing

    History and timing

    The type of surgery, the mesh used and the interval since implantation shape the whole differential. Early infection behaves very differently from delayed biofilm disease.

  2. 02

    Assessing

    Examination

    Look for wound breakdown, discharging sinuses, cellulitis, fluctuance and any sign of enterocutaneous fistula, which is a specialist emergency.

  3. 03

    Assessing

    Inflammatory bloods and cultures

    Full blood count, CRP, blood cultures and swabs. In septic patients this drives empirical antibiotic choice while deeper sampling is arranged.

  4. 04

    Confirming

    Ultrasound and CT

    Ultrasound identifies superficial collections. A private CT scan (see /treatments/private-ct-scan/) maps deep collections, fistulae and mesh position. MRI is used selectively.

  5. 05

    Confirming

    Aspiration and tissue sampling

    Percutaneous aspiration and tissue biopsy with specialist microbiology, including atypical and mycobacterial cultures, is often needed to isolate biofilm organisms.

  6. 06

    Planning

    Specialist commissioned referral

    Complex hernia and urogynaecology cases are managed at specialist commissioned centres such as Sheffield and Bristol, with formal MDT input.

  7. 07

    Planning

    MDT planning

    Surgeon, microbiologist, interventional radiologist and reconstructive team agree the pathway - drainage, antibiotic course and any planned explantation and reconstruction.

Typical timeline: from first review to a specialist plan in days, not weeks.

Symptoms

What infected mesh actually looks like.

Local wound problems, systemic infection and pelvic mesh complications - and the features that mean it is time to escalate.

  • Local pain and tenderness

    Persistent or worsening pain over the mesh site, often out of keeping with the stage of healing.

  • Erythema and warmth

    Spreading redness and heat over the wound or implant site, suggesting cellulitis or deeper infection.

  • Wound breakdown and discharge

    Delayed healing, dehiscence and purulent or serous discharge from the incision.

  • Sinus or fistula

    A chronic discharging sinus, or an enterocutaneous fistula, points strongly to mesh involvement and needs specialist input.

  • Swelling and induration

    A firm, tender mass around the mesh may represent an abscess or a chronic inflammatory phlegmon.

  • Fever and systemic upset

    Rigors, tachycardia or hypotension suggest sepsis and require urgent hospital assessment.

  • Urogynaecology symptoms

    Vaginal discharge, dyspareunia, exposure of mesh or new pelvic pain after transvaginal mesh insertion.

  • Red flag - sepsis or fistula

    Sepsis, an enterocutaneous fistula or exposed mesh is a specialist emergency and needs same-day surgical review.

Treatment

How infected mesh is treated in the UK.

Antibiotics first, drainage where feasible, and mesh explantation with reconstruction when infection is established. Urogynaecology follows a separate specialist commissioned pathway.

  • Broad-spectrum antibiotics

    Empirical intravenous cover on presentation, narrowed to culture-directed oral therapy. Courses are often prolonged and co-ordinated with specialist microbiology.

  • Percutaneous drainage

    Image-guided drainage of collections by interventional radiology, sometimes as the definitive treatment for localised abscesses.

  • Mesh explantation

    Definitive treatment for most established infections. Performed at a specialist commissioned complex hernia centre where salvage has failed or biofilm is confirmed.

  • Abdominal wall reconstruction

    Component separation, biological mesh or autologous reconstruction after explantation, restoring the abdominal wall in one or staged operations.

  • Urogynaecology mesh removal

    Full or partial removal of pelvic mesh at a specialist commissioned centre under the post-Cumberlege pathway, including counselling and shared decision-making.

  • Chronic pain and psychological support

    Structured pain management, physiotherapy and psychological support recognising the long-term impact on wellbeing.

  • Recurrence prevention

    Patient optimisation, glycaemic control, smoking cessation, prophylactic antibiotics and careful mesh selection at any future repair.

  • Multidisciplinary follow-up

    Surgeon, microbiologist, pain specialist and psychologist co-ordinate long-term care within a specialist commissioned service.

Key references

Guidelines and standards we relied on.

A quiet reminder

This guide is for information, not medical advice.

Your surgical team and the specialist commissioned centre know your history and imaging and can tell you which parts apply to you. If in doubt, get seen.

Red flags

When infected mesh needs urgent attention.

Some situations cannot wait for a routine referral. These are the ones that need a same-day surgical opinion.

  • Sepsis

    Fever, tachycardia, hypotension or confusion in a patient with mesh in situ needs same-day hospital assessment and blood cultures.

  • Enterocutaneous fistula

    Bowel content discharging from a wound is a specialist emergency, requiring nutritional and surgical input at a complex hernia centre.

  • Exposed or eroded mesh

    Mesh visible in a wound or vaginally after urogynaecological surgery needs urgent specialist review, not observation.

  • Rapidly spreading cellulitis

    Extending erythema, crepitus or systemic upset raises concern for necrotising infection and needs emergency surgical care.

  • Mycobacterium abscessus and atypicals

    Chronic, minimally inflamed sinuses that fail routine antibiotics need specialist microbiology and atypical mycobacterial cultures.

  • Urogynaecological mesh complications

    New pelvic pain, dyspareunia, urinary symptoms or partner discomfort after transvaginal mesh should be reviewed through a specialist commissioned centre.

  • Recurrent hernia over infected mesh

    New bulge or discomfort at the site of a previously repaired hernia may signal recurrence and infection together.

  • Chronic pain and psychological impact

    Persistent pain and low mood after mesh surgery deserve formal review, not dismissal, and are recognised parts of the pathway.

  • Failed outpatient antibiotics

    Two or more courses of oral antibiotics without resolution should prompt imaging and specialist referral, not repeat prescribing.

Living with it

A treatable complication, with the right team.

Four things that make the biggest difference: early review, a specialist commissioned centre, patient optimisation and holistic support.

A quiet reminder

The right team, at the right time, changes outcomes.

Complex mesh work belongs in centres that do it week in, week out. Ask for that referral early.

  1. 01 Care

    Get seen early

    Persistent pain, discharge or swelling around a mesh site is never routine. Early specialist review protects the mesh and shortens recovery.

  2. 02 Team

    A specialist commissioned pathway

    Complex hernia and urogynaecological mesh work happens in a small number of specialist commissioned UK centres. Ask to be referred if your case is not routine.

  3. 03 Optimise

    Prepare the ground

    Smoking cessation, weight optimisation and glycaemic control materially reduce the risk of further infection and reconstruction failure.

  4. 04 Support

    Look after the whole picture

    Pain, sleep, mood and confidence all take a hit. Structured physiotherapy and psychological support are part of the plan, not an afterthought.

Frequently asked

Everything we get asked about infected mesh.

Quick answers on timing, organisms, mesh types, urogynaecological mesh and long-term recovery.

  • What is infected mesh?

    Infected mesh is bacterial or, less often, mycobacterial infection of a synthetic or biological implant used in hernia repair or urogynaecological surgery. It presents as pain, redness, wound breakdown, discharge or systemic sepsis and is confirmed with imaging, aspiration and microbiology.

  • How soon after surgery does it appear?

    Early infection appears within thirty days and is usually driven by Staphylococcus aureus, streptococci or gram-negative organisms. Delayed infection appears months or years later, is biofilm-driven, and is often caused by coagulase-negative staphylococci, MRSA or Mycobacterium abscessus.

  • Does the type of mesh matter?

    Yes. Polypropylene, PTFE, composite and biological meshes behave differently. Some infections can be salvaged with antibiotics and drainage, especially in lightweight polypropylene. Others, particularly PTFE and heavily contaminated meshes, usually need explantation at a specialist commissioned centre.

  • What happens with urogynaecological mesh?

    Transvaginal mesh has been withdrawn in the UK following the Cumberlege Review. Complications are managed through a specialist commissioned pathway at centres such as Sheffield and Bristol, with careful counselling before any full or partial removal.

  • Can antibiotics alone cure it?

    Sometimes, particularly for early, superficial infections with a susceptible organism. Established biofilm infection almost always needs source control - drainage or mesh removal - because antibiotics cannot penetrate mature biofilm reliably.

  • What does long-term recovery look like?

    Recovery depends on the mesh, the organism and whether reconstruction is needed. Many people do well after explantation and abdominal wall reconstruction, but chronic pain, recurrent hernia and psychological effects are recognised and are managed within a multidisciplinary specialist commissioned service.
