Diagnosis and Treatment Percutaneous Tibial Neuromodulation (PTNM)
The American Urological Association and Society of Urodynamics, Female Pelvic Medicine & Urogenital Reconstruction Guideline for the diagnosis and treatment of overactive bladder (OAB) in adults is to provide a clinical framework for the diagnosis and treatment of non-neurogenic overactive bladder. The guidance lists Percutaneous Tibial Nerve Stimulation (PTNS), otherwise known as PTNM, as an acceptable treatment in a carefully selected patient population.1
The number of OAB patients is staggering. OAB is more common than diabetes and the incidence increases every year as the baby boomer population ages.2,3,4,5
In spite of this high prevalence, the number of patients presenting OAB symptoms to their clinician is much lower. Many symptomatic patients will not present to their provider for treatment9,10,11 because they see symptoms as a nuisance or as an embarrassment.12,13
Millions of OAB patients are looking for a treatment option that can restore* bladder function and help them improve their quality of life.
Patient compliance with medications, such as anticholinergics (ACs), is low due to variable efficacy and side effects, such as dry mouth and constipation.1 As many as 7 in 10 patients give up taking medication within 6 months.14,15
Percutaneous tibial neuromodulation (PTNM) delivered by the NURO™ system is an effective alternative treatment option for patients reluctant to try medications. Drug-naïve OAB patients treated with NURO PTNM therapy experience a nearly 70% reduction in urgency urinary incontinence episodes (UUIE).16
PTNM is also an alternative for patients whose symptoms have previously failed to respond to medications, but who are not a good candidate for sacral neuromodulation therapy.
With PTNM, restored bladder function is defined as a measurable reduction in urinary frequency and/or urinary incontinence episodes following treatment.
