The FDA has the authority to require sponsors to perform a post-approval study (or studies) at the time of approval of a premarket approval (PMA), humanitarian device exemption (HDE), or product development protocol (PDP) application. Post-approval studies can provide patients, health care professionals, the device industry, the FDA and other stakeholders information on the continued safety and effectiveness (or continued probable benefit, in the case of an HDE) of approved medical devices. This database allows you to search Post-Approval Study information by applicant or device information.

Scores can range from 4-17. Safety is measured by: Use of pain medication pre-treatment and during treatment, Pain associated with treatment, Local and systemic symptoms during Prolieve treatment

Catheterizations associated with treatment, PSA levels, Adverse events, Anticipated adverse events (associated with treatment or BPH), Hospitalizations , and MDR reportable events.
