Thulio versus Holmium lasers for removing enlarged prostate tissue

Evaluating the Clinical Efficacy of Thulio vs. Holmium Laser Enucleation of the Prostate

Not applicable Interventional The Cleveland Clinic · NCT07187180

This trial will test whether the new pulsed Thulio (thulium) laser works as well as the standard holmium laser for men with enlarged prostates and urinary symptoms.

What this trial studies

This is a prospective randomized comparison of pulsed thulium (Thulio) laser enucleation versus standard holmium laser enucleation for men undergoing prostate enucleation for BPH. Patients are randomized in equal numbers and evaluated before the procedure and at one follow-up visit. The primary endpoint is non-inferiority for hemostasis timing, and secondary endpoints include enucleation time, active laser time, morcellation time, change in hemoglobin, total applied laser energy, enucleation efficacy (g/min), IPSS, QoL, uroflowmetry, post-void residual, prostate volume, and catheter duration. The trial excludes men with prior prostate surgery, bladder stones requiring lasering, or those who cannot safely hold anticoagulants per protocol.

Who should consider this trial

Good fit: Men aged 18 or older with BPH causing urinary symptoms or obstruction, no prior prostate surgery, and who can temporarily stop anticoagulants per protocol are ideal candidates.

Not a fit: Patients with prior prostate surgery, bladder stones that require lasering, or those unable to safely pause anticoagulants are unlikely to qualify and may not receive benefit from this comparison.

Why it matters

Potential benefit: If Thulio is non-inferior or better, patients could experience similar or improved bleeding control and operative efficiency, potentially shortening surgery time and recovery.

How similar studies have performed: Holmium and thulium enucleation techniques are established with good outcomes, but randomized comparisons of pulsed thulium (Thulio) versus standard holmium lasers remain limited.
