Health condition
Percutaneous tibial nerve stimulation
Percutaneous tibial nerve stimulation (PTNS) treats overactive bladder by stimulating a nerve at the ankle that shares spinal wiring with the bladder - a needle-fine electrode, 30 minutes, no drugs.

Key facts
The essentials at a glance.
The symptoms to recognise, when to seek help, which specialist to see, and what treatment usually involves.
-
Who it suits: people with urgency, frequency or urge leakage who have not responded to or cannot tolerate bladder medication, and prefer to avoid Botox or implants
-
PTNS is very low-risk; report any persistent discomfort or skin reaction at the ankle site
-
Specialist: a consultant urologist usually leads assessment and treatment
-
The course: weekly 30-minute sessions for 12 weeks, then maintenance top-ups (typically monthly) for responders - improvement is seen in a majority of suitable patients
Understanding the condition
What it is and what happens next.
What causes it, how it is diagnosed, and the treatment routes available in the UK.
What it is and how it feels
A fine needle electrode placed near the inner ankle delivers gentle electrical pulses along the tibial nerve to the sacral nerve roots that govern bladder reflexes, gradually retuning them. It is the least invasive of the neuromodulation options - no anaesthetic, no implant, no medication side effects - and sits naturally after failed tablets and before Botox or sacral implants on the treatment ladder.
Diagnosis and treatment routes
Around 60-70% of patients respond meaningfully across trials, though benefit needs maintaining with periodic sessions, and newer implantable tibial devices are extending the concept. A urologist or specialist continence service will confirm you are a suitable candidate and structure the 12-week course with objective before-and-after measures such as a bladder diary. In many parts of the UK, routine NHS referrals for this kind of problem currently take 20-45+ weeks, whereas an initial appointment with a private consultant is typically available within around two weeks.
Seeing a specialist
Who to see, and how quickly you can be seen.
The specialist for this condition is usually a consultant urologist. Your GP can refer you on the NHS, or you can arrange a private consultation directly.
A quiet reminder

Your GP knows your history and can tell you which parts apply to you. If in doubt, see them - and seek urgent care for any of the emergency symptoms described above.
Frequently asked
Common questions about Percutaneous tibial nerve stimulation.
Quick, plain-English answers to what people ask us most.
-
What is Percutaneous tibial nerve stimulation?
Percutaneous tibial nerve stimulation is a recognised medical condition that affects the body in ways specific to its underlying cause. Getting an accurate diagnosis is the first step towards understanding your options and what to expect.
-
What causes Percutaneous tibial nerve stimulation?
The underlying cause can involve a mix of genetic, environmental, and lifestyle factors, and in some cases no single clear cause is identified. Your doctor can help clarify which factors are most relevant to your case based on your history and any test results.
-
What are the symptoms of percutaneous tibial nerve stimulation?
Symptoms can vary from mild to significant and often develop gradually, though some people notice a more sudden onset. Because symptoms overlap with other conditions, a proper clinical assessment is important for an accurate diagnosis.
-
Is percutaneous tibial nerve stimulation serious or dangerous?
Most cases are manageable with appropriate treatment, though severity varies from person to person. Left unaddressed, some cases can lead to complications, so getting an assessment rather than waiting is generally the safer approach.
-
Is percutaneous tibial nerve stimulation hereditary or genetic?
Some cases have a genetic component that runs in families, while others develop without any inherited link, arising instead from environmental or lifestyle factors. If you have a strong family history, mentioning this to your doctor can help guide whether genetic assessment is worthwhile.
-
How is percutaneous tibial nerve stimulation treated?
Treatment approaches vary depending on severity and individual circumstances, and may include lifestyle changes, medication, or referral to a specialist for more targeted therapy. Your GP or specialist will tailor a plan based on your specific situation.
-
How long does percutaneous tibial nerve stimulation last?
Duration varies — some cases are short-lived and resolve fully with treatment, while others are longer-term or chronic conditions managed over time. Your doctor can give you a more specific expectation once they understand your individual case.
-
When is surgery or specialist treatment needed?
Specialist or surgical treatment is usually considered when simpler treatments haven't controlled symptoms adequately, or when the condition is affecting quality of life or function significantly. A specialist assessment can clarify whether this applies to your situation.
-
When should I see a doctor about percutaneous tibial nerve stimulation?
See a doctor if symptoms are new, worsening, or affecting your daily life. On the NHS, routine referrals to a specialist can take 20 to 45 weeks or longer depending on your area; with private healthcare you can typically see a consultant within about 2 weeks, which can be worthwhile if you want a faster diagnosis or reassurance.
-
Can lifestyle changes help manage percutaneous tibial nerve stimulation?
Alongside medical treatment, factors such as a balanced diet, regular appropriate exercise, stopping smoking, and managing stress can support recovery and reduce the risk of the condition worsening or recurring. Your healthcare team can advise which lifestyle changes are most relevant to your specific condition.
