What this trial studies

This clinical trial evaluates the effectiveness of Thulium Fiber Laser (TFL) compared to Holmium MOSES laser for treating benign prostatic hyperplasia (BPH). BPH causes urinary issues due to prostate enlargement, and traditional treatments like TURP have significant risks. The trial aims to determine if TFL can provide a safer and more efficient alternative to the Holmium laser technique, which is already recognized for its benefits but is complex to perform. Participants will be men over 50 who have not responded to medical treatments for BPH.

Who should consider this trial

Good fit: Ideal candidates are males over 50 with refractory lower urinary tract symptoms or urinary retention due to BPH who have failed medical treatment.

Not a fit: Patients with a history of prostate cancer or previous surgical treatment for BPH will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could offer a safer and more effective treatment option for men suffering from BPH.

How similar studies have performed: Previous studies have shown that laser treatments like HoLEP can be effective, suggesting potential success for this novel approach with TFL.
