Summary
The eCoin device shows promise for treating overactive bladder (OAB) with low complication rates. Further long-term studies are needed to confirm its durability as a management option.
Area of Science:
- Neurology
- Urology
- Biomedical Engineering
Background:
- Peripheral nerve stimulation is an alternative to sacral nerve stimulation for refractory overactive bladder (OAB).
- Implantable tibial nerve stimulators offer new technological advancements for OAB management.
- The eCoin is a coin-shaped, implantable tibial nerve stimulator providing pre-programmed stimulation.
Purpose of the Study:
- To review the literature on eCoin implantation for overactive bladder (OAB).
- To analyze the efficacy, durability, and adverse events of the eCoin device.
- To assess the viability of eCoin as a long-term management option for OAB.
Main Methods:
- Literature review of studies on eCoin implantation.
- Analysis of proof-of-concept and mid-term follow-up data (up to 12 months).
- Evaluation of current implantable neuromodulators for OAB.
Main Results:
- eCoin demonstrates promising early efficacy in managing OAB symptoms.
- Complication rates are low, primarily associated with wound healing post-implantation.
- Mid-term data suggests potential but requires longer-term follow-up.
Conclusions:
- The eCoin device shows potential for OAB management with a favorable safety profile.
- Longer-term data is essential to establish eCoin as a mainstay treatment.
- Implantable percutaneous tibial nerve stimulation (PTNS) holds a role in the future of OAB management.
