Summary
Long-term neuromodulation for refractory lower urinary symptoms showed mixed results. While effective for chronic urinary retention, benefits for urgency/frequency and incontinence diminished over time.
Area of Science:
- Urology
- Neuromodulation
- Pelvic Health
Background:
- Refractory lower urinary symptoms, including urgency/frequency, incontinence, and urinary retention, significantly impact quality of life.
- Neuromodulation offers a treatment option for patients with these challenging conditions.
Purpose of the Study:
- To evaluate the long-term efficacy and outcomes of neuromodulation using the NeuroStim system.
- To analyze results in patients with urgency/frequency, urgency incontinence, and chronic urinary retention.
Main Methods:
- Retrospective analysis of 52 patients implanted since 1990 with strict inclusion criteria.
- Included temporary percutaneous nerve evaluation and a 50% improvement threshold for implantation.
- Follow-up included clinical visits and telephone questionnaires for 41 available patients.
Main Results:
- Overall, 5 of 41 patients required explantation.
- Persistent improvement was observed in 45% of urgency/frequency patients and 17% of urgency incontinence patients.
- Significant improvement was noted in 78% of chronic urinary retention patients.
Conclusions:
- Long-term neuromodulation outcomes for urgency/frequency and incontinence were not consistently maintained.
- Patients with chronic urinary retention demonstrated more favorable long-term results with neuromodulation.
- Neuromodulation remains a viable option for select patients, particularly those with chronic urinary retention.
