Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a prospective data collection of subjects using blude diode laser for the treatment of BPH.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a prospective single-arm study evaluating the outcome of blue diode laser vaporization. The energy from a 450nm blue laser vaporization will be used for the treatment of BPH. The study period for each patient is 1 year. Recruited subjects will then be followed up at 3 months, 6 months and 12 months after operation. Blood tests, urine tests, ultrasound for prostate volume assessment, uroflowmetry and the same set of questionnaires will be performed again during follow-up for assessing the clinical progress. Any adverse event and unplanned admission will also be documented.
