Clinical Scorecard: Assessment of Safety and Effectiveness of an Implantable Tibial Neuromodulation Device for Treating Overactive Bladder with Urgency Urinary Incontinence: Results from a Single-Arm Open-Label Study

At a Glance

CategoryDetail
ConditionOveractive Bladder with Urgency Urinary Incontinence
Key MechanismsImplantable tibial neuromodulation system (iTNS) for neuromodulation of bladder activity.
Target PopulationPatients with refractory overactive bladder and urgency urinary incontinence.
Care SettingSingle-center open-label trial.

Key Highlights

  • 90% response rate at 6 months with iTNS system.
  • 40% of patients achieved ≥3 consecutive dry days.
  • Significant reduction in UUI episodes from 3.235 to 0.632 per day at 6 months.
  • Quality of life improved significantly as per validated questionnaires.
  • 80% of patients reported satisfaction with symptoms at 6 months.

Guideline-Based Recommendations

Diagnosis

  • Diagnosis of OAB can be made in the absence of urinary tract infection or identifiable pathologies.

Management

  • Consider iTNS for patients with intractable symptoms despite first-line and second-line treatments.

Monitoring & Follow-up

  • Follow-up evaluations at 1, 3, and 6 months post-implantation.

Risks

  • Potential device-related adverse events such as pain and infection.

Patient & Prescribing Data

Chinese patients with refractory overactive bladder.

iTNS offers a minimally invasive alternative with continuous, patient-controlled neuromodulation.

Clinical Best Practices

  • Utilize validated questionnaires for assessing quality of life and symptom satisfaction.
  • Implement a step-wise treatment approach for OAB management.
