Summary
Sacral neuromodulation (SNM) is generally well tolerated, but patients with lower BMI, younger age, and males may experience more physical burden from the implantable pulse generator (IPG). Tailored counseling is recommended.
Area of Science:
- Urology
- Gastroenterology
- Biomedical Engineering
Background:
- Sacral neuromodulation (SNM) effectively treats refractory bowel and urinary dysfunction.
- Patient satisfaction with SNM is established, but the physical impact of the implantable pulse generator (IPG) is less understood.
Purpose of the Study:
- To evaluate patient perspectives on the physical burden of the gluteal IPG used in sacral neuromodulation.
Main Methods:
- A survey was administered to 100 SNM patients regarding IPG-related concerns.
- Data were collected via follow-up visits or phone interviews.
- Descriptive analysis and statistical testing were performed.
Main Results:
- Most patients tolerated SNM well; 62% were aware of the IPG, 18% reported movement limitations, and 36% experienced activity discomfort.
- Lower BMI correlated with increased discomfort.
- Male and younger patients were more likely to deactivate the device.
Conclusions:
- SNM is generally well-tolerated, but device-related burden varies.
- Leaner, younger, and male patients may require more specific counseling regarding potential physical impacts.
- Optimizing device placement and patient education is crucial for managing SNM physical burden.
