What is the mechanism of action of this treatment?

Laser-based treatments for an enlarged prostate, such as Thulium Fiber Laser Enucleation (ThuFLEP) and Holmium Laser Enucleation of the Prostate (HoLEP), utilize high-energy lasers to precisely remove excess prostate tissue. These lasers create a vaporization bubble that destroys prostatic tissue with minimal deep tissue penetration, reducing the risk of bleeding and other complications. ThuFLEP, in particular, uses a high wavelength and pulsed mode of action, which allows for efficient and safe enucleation of large prostate volumes. These treatments are significant for BPH patients as they offer minimally invasive options with shorter hospital stays, reduced catheterization times, and lower risks of perioperative bleeding, making them suitable for patients on anticoagulation therapy.

What side effects are associated with this type of intervention?

Thulium Fiber Laser Enucleation of the Prostate (ThuFLEP) and Holmium Laser Enucleation of the Prostate (HoLEP) are advanced treatments for benign prostatic hyperplasia (BPH). Common side effects of these laser-based treatments include transient stress urinary incontinence, which is usually temporary, and a longer operative time compared to traditional methods like Transurethral Resection of the Prostate (TURP). Both ThuFLEP and HoLEP are associated with minimal blood loss, shorter catheterization times, and decreased hospital stays. However, there is a risk of perioperative bleeding complications, though this is generally lower than with TURP. Additionally, patients on anticoagulation therapy may experience slightly longer durations of bladder irrigation and hospital stays.

What prior FDA approvals exist?

The FDA has approved several laser-based treatments for benign prostatic hyperplasia (BPH), including Holmium Laser Enucleation of the Prostate (HoLEP) and Photoselective Vaporization of the Prostate (PVP). These treatments, like Thulium Fiber Laser Enucleation (ThuFLEP), use laser energy to remove or vaporize excess prostate tissue, thereby relieving urinary symptoms. HoLEP, in particular, is known for its efficacy in treating large prostate volumes with minimal bleeding risk, similar to the high wavelength and pulsed mode of action seen in ThuFLEP.

What other types of research exist?

Promising novel alternatives to Thulium Fiber Laser Enucleation (ThuFLEP) for treating an enlarged prostate in 2024 include Holmium Laser Enucleation of the Prostate (HoLEP) with MOSES technology, which offers efficient tissue removal with minimal blood loss, and Robotic Waterjet Treatment (RWT), which uses a high-velocity waterjet for precise tissue ablation while sparing major blood vessels.

Summary

This trial compares two laser treatments for men with an enlarged prostate. These treatments aim to remove excess prostate tissue with less bleeding and faster recovery than traditional methods. One treatment uses a Thulium laser, while the other uses a Holmium laser.

Who is the study for?

This trial is for men over 50 with severe urinary symptoms from an enlarged prostate (BPH) who haven't improved with medication. They must have a prostate size of ≥80 ml, be able to follow study procedures, and give informed consent in English. Men with urethral stenosis history, prostate cancer, active infections or previous BPH surgery are excluded.

What is being tested?

The study compares two laser treatments for BPH: Thulium Fiber Laser (TFL) enucleation and Holmium MOSES Laser enucleation. It aims to see if they're equally effective in reducing hospital stay time and improving intraoperative and postoperative outcomes.

What are the potential side effects?

Potential side effects may include bleeding requiring blood transfusion, late postoperative bleeding similar to TURP complications but expected less due to the nature of laser treatments which typically result in minimal blood loss.
