The main idea here is how the device’s energy is replenished and how that affects what the patient has to do over time. A rechargeable SNM system uses a battery that you replenish with an external charger. The patient will need to charge the implanted generator regularly to keep therapy going, so maintenance involves charging sessions rather than surgeries. A non-rechargeable SNM has a battery inside that isn’t recharged. When that battery runs out, the generator powers down and must be surgically replaced with a new one to restore therapy. This distinction drives two very different patient experiences: regular charging versus periodic surgical replacements. That’s why this option fits best. The statement reflects the practical difference in upkeep between the two types. The other choices are off because rechargeable devices are not implanted externally, non-rechargeable devices do require maintenance (replacement surgeries), and there is a difference in maintenance between the two.
