Summary
Rechargeable sacral neuromodulation (SNM) devices for overactive bladder show higher revision rates than non-rechargeable ones. Common issues include charging problems and reduced symptom improvement, necessitating further investigation into these factors.
Area of Science:
- Urology
- Biomedical Engineering
Background:
- Overactive bladder (OAB) significantly impacts quality of life.
- Sacral neuromodulation (SNM) is an effective OAB treatment.
- Rechargeable SNM devices are increasingly used, but revision data is limited.
Purpose of the Study:
- To investigate revision rates for rechargeable versus non-rechargeable SNM devices in OAB patients.
- To identify factors associated with revisions in SNM devices.
Main Methods:
- Retrospective cohort study of 246 OAB patients.
- Comparison of revision rates between rechargeable (n=150) and non-rechargeable (n=96) SNM devices.
- Analysis of revision events, reasons, and patient demographics.
Main Results:
- Higher revision rates in the rechargeable group (34%) compared to non-rechargeable (13.5%) (p < 0.001).
- Common revision reasons for rechargeable devices: difficulty charging (35.3%) and reduced symptom improvement (23.5%).
- Rechargeable devices showed a significantly higher probability of revision over time (p < 0.001).
Conclusions:
- Rechargeable SNM devices are associated with increased revision likelihood in OAB patients.
- Device malfunction and connectivity issues may drive higher revision rates.
- Further research is needed to understand factors influencing SNM device revision rates.

01:19Ligand-gated Ion Channels
Ligand-gated ion channels are transmembrane proteins with a channel for ions to pass through and a binding site for a ligand. The channel opens only when a ligand attaches to the binding site.
Three Subfamilies of Ligand-gated Ion Channels
Ligand-gated ion channels fall into three subfamilies. The 'Cys-loop' includes the nicotinic acetylcholine receptors, γ-aminobutyric acid (GABA), glycine, and 5-hydroxytryptamine receptors. The second one is the 'Pore-loop' channels that include the...

01:30Ligand-Gated Ion Channel Receptor: Gating Mechanism
Ligand-gated ion channels are transmembrane proteins that play a vital role in intercellular communication and functions of the nervous system. They allow the influx of ions across the membrane once the neurotransmitter binds, allowing the subsequent transmission of electrical excitation across the neurons. Other ligand-gated ion channels, like the γ-aminobutyric acid (GABA) receptor, permit anions like chloride into the cells on the binding of the GABA molecule. Their entry into the cell...
01:22Muscle Stimulation Frequency
The contraction strength of muscles is regulated by motor neurons, which modulate the frequency of action potentials dispatched to the motor units based on the body's requirements. This process of varying the muscle stimulation frequency allows muscles to contract with a force that is precisely tailored to the needs of the moment, whether lifting a feather or a heavy box.

01:28Load-frequency control
Load-frequency control (LFC) is vital for maintaining power system stability, ensuring that frequency and power flows remain within acceptable limits during load changes. Turbine-governor control eliminates rotor accelerations and decelerations following load changes. However, a steady-state frequency error persists when the change in the turbine-governor reference setting is zero. In an interconnected power system, each area agrees to export or import a scheduled amount of power through...
