About

Enucleation of the prostate equips technology (usually laser) to effectively treat lower urinary tract symptoms associated with benign prostate hyperplasia (BPH). The holmium: yttrium-aluminum-garnet (Ho: YAG) laser is considered the gold standard laser used to perform enucleation of the prostate. Holmium laser enucleation of the prostate (HoLEP) reduces hospital stay and hemoglobin drop while improving International Prostate Symptom Score (IPSS) and quality of life, as well as other postoperative outcomes. HoLEP has been found to have a better enucleation efficiency rate and may have better hemostatic properties when combined with the modulated pulsed laser energy featured associated with Moses technology (m-HoLEP).

A novel laser technology called thulium fiber laser (TFL) delivers a pulsed laser at a more optimal wavelength and a shallower depth of tissue penetration leading to better hemostatic properties. However, the differences in clinical outcomes between TFL enucleation of the prostate (TFLEP) and m-HoLEP have yet to be described. This prospective study aims to compare the safety profile and clinical outcomes, peri-operatively up to one year post-operatively, between m-HoLEP and TFLEP with BPH and evidence of bladder obstruction.

Full description

Enucleation of the prostate equips technology (usually laser) to effectively treat lower urinary tract symptoms associated with benign prostate hyperplasia (BPH). The holmium: yttrium-aluminum-garnet (Ho: YAG) laser is the longest running and most studied laser used to perform this minimally invasive procedure.

Holmium laser enucleation of the prostate (HoLEP) reduces hospital stay and hemoglobin drop while improving IPSS and quality of life, as well as other positive postoperative outcomes. HoLEP has been found to have a better enucleation efficiency rate and may have better hemostatic properties when combined with the modulated pulsed laser energy featured associated with Moses technology (m-HoLEP).

A novel laser technology called thulium fiber laser (TFL) delivers a pulsed laser at a more optimal wavelength and a shallower depth of tissue penetration leading to better hemostatic properties. However, the differences in clinical outcomes between TFL enucleation of the prostate (TFLEP) and m-HoLEP, to our knowledge, have yet to be described.

This prospective study aims to compare the safety profile and clinical outcomes, peri-operatively up to one year post-operatively, between m-HoLEP and TFLEP with BPH and evidence of bladder obstruction. Variables of particular interest include the length of hospital stay and the need for blood transfusion, which are benefits of both techniques compared to transurethral resection of the prostate, the current gold standard of BPH treatment according to American Urological Association (AUA) guidelines. The results of this study will guide urologists in selecting the most appropriate procedure from the growing armamentarium of treatments for BPH.

TFLEP

Active Comparator group

Description:

Thulium fiber laser (TFL) is a novel laser technology that delivers a pulsed laser at a more optimal wavelength and a shallower depth of tissue penetration leading to better hemostatic properties. Patients will undergo thulium fiber laser enucleation of the prostate (TFLEP) at the Centre Hospitalier de l'Université de Montréal (CHUM) as a treatment for benign prostate hyperplasia. The surgeon performing TFLEP is experienced in TFLEP procedures.

Procedure: TFLEP

m-HoLEP

Active Comparator group

Description:

The holmium: yttrium-aluminum-garnet (Ho: YAG) laser is the longest running and most studied laser used to perform this minimally invasive procedure. Holmium laser enucleation of the prostate reduces hospital stay and hemoglobin drop while improving IPSS and quality of life, as well as other positive postoperative outcomes compared to the historical gold standard, transurethral resection of the prostate (TURP). HoLEP has been found to have a better enucleation efficiency rate and may have better hemostatic properties when combined with the modulated pulsed laser energy featured associated with Moses technology (m-HoLEP). Patients will undergo m-HoLEP at the Centre intégré universitaire de santé et de services sociaux (CIUSSS) du Nord-de-l'Île-de-Montréal as a treatment for benign prostate hyperplasia. The surgeon performing m-HoLEP is experienced in m-HoLEP procedures.
