What this trial studies

This study compares the safety and clinical outcomes of two laser techniques, thulium fiber laser enucleation of the prostate (TFLEP) and holmium laser enucleation of the prostate with Moses technology (m-HoLEP), in treating benign prostatic hyperplasia (BPH). It aims to evaluate factors such as hospital stay length and blood transfusion needs in patients with BPH and bladder obstruction. The study will follow patients for up to one year post-operatively to assess the effectiveness of each treatment method.

Who should consider this trial

Good fit: Ideal candidates include men with symptomatic benign prostatic hyperplasia who have not responded adequately to previous medical treatments.

Not a fit: Patients with a history of prostate or bladder cancer, neurogenic bladder, or those unfit for surgery may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide patients with a more effective and safer treatment option for benign prostatic hyperplasia.

How similar studies have performed: While the holmium laser technique is well-established, the thulium fiber laser approach is relatively novel, and this study aims to provide new insights into its effectiveness compared to existing methods.
