Summary
Non-invasive sacral nerve stimulation significantly increased bladder storage capacity in patients with reduced bladder function. This effective, less invasive approach offers a promising alternative to traditional treatments for bladder storage issues.
Area of Science:
- Urology
- Neurology
- Medical Engineering
Background:
- Intractable diminished bladder storage function is a common clinical challenge.
- Current treatments like sacral neuromodulation are invasive and costly.
- There is a need for less invasive and more accessible therapeutic options.
Purpose of the Study:
- To evaluate the efficacy of non-invasive third sacral nerve (S3) stimulation on bladder activity.
- To assess the impact of transcutaneous sacral neurostimulation during filling cystometry.
Main Methods:
- 146 patients with diminished bladder storage underwent repeated urodynamic filling cystometry.
- The study group (n=74) received transcutaneous sacral neurostimulation during the second fill.
- The control group (n=72) had a second fill without neurostimulation.
Main Results:
- Neurostimulated patients showed a statistically significant increase in bladder storage capacity.
- This improvement occurred without a concurrent rise in detrusor pressure.
- Transcutaneous S3 stimulation demonstrated a positive effect on bladder function.
Conclusions:
- Non-invasive S3 stimulation effectively improves functional bladder capacity.
- This modality presents a promising, less invasive alternative to existing treatments.
- Findings support the clinical use of non-invasive sacral neurostimulation for bladder storage dysfunction.
