What this trial studies

This is a prospective, single-arm study using a 450 nm blue diode laser to vaporize prostate tissue in men with symptomatic BPH. Each participant is followed for one year with visits at 3, 6, and 12 months after the operation. Clinical follow-up includes blood and urine tests, prostate ultrasound for volume, uroflowmetry, and symptom questionnaires, and all adverse events and unplanned admissions are recorded. The study aims to document safety and clinical outcomes of the blue diode vaporization technique.

Who should consider this trial

Good fit: Men aged 50 years or older with symptomatic benign prostatic hyperplasia who are fit for the procedure and anesthesia are ideal candidates.

Not a fit: Patients with prior TURP, known prostate cancer, urethral stricture, bladder stones, significant neurological bladder dysfunction, active urinary infection, or who cannot undergo anesthesia are unlikely to be eligible or benefit.

Why it matters

Potential benefit: If successful, the procedure could reduce urinary symptoms and improve urine flow using a minimally invasive laser vaporization approach.

How similar studies have performed: Other laser treatments for BPH (for example, green and holmium lasers) have demonstrated good outcomes, but the 450 nm blue diode approach is novel and currently has limited published data.
