What goals are researchers aiming to achieve with this clinical investigation?

"Over a period of one week, beginning on the day of discharge following device placement, this trial intends to measure how effectively the Spring Implant can mitigate symptoms associated with Benign Prostatic Hyperplasia (BPH) by utilizing an International Prostate Symptom Score. In addition to evaluating efficacy, secondary outcomes such as pain levels evaluated through a Visual Analog Scale (VAS), and changes in sexual health measured via Sexual Health Inventory for Men (SHIM) questionnaire score will be observed. Lastly, any Clavien-Dindo events that result in persistent disability up until three months post treatment will also be monitored."
