Clinical Scorecard: Analysis of Perioperative Factors Using Multivariable Regression for a New High-Peak Power Pulsed Solid-State Thulium: YAG Laser Compared to Holmium: YAG Laser in Prostate Enucleation

At a Glance

Key Highlights

• Pulsed solid-state Thulium: YAG laser has higher peak power (3,700 W) and wavelength (2013 nm) close to water absorption peak, enabling efficient tissue ablation with less penetration and damage than Holmium: YAG laser.
• Laser enucleation of the prostate (LEP) is recommended over TURP due to lower bleeding risk and shorter hospitalization.
• Both HoLEP and pulsed ThuLEP performed with en-bloc technique by experienced surgeons using standardized protocols including monopolar electrocautery for hemostasis.

Guideline-Based Recommendations

Diagnosis

• Diagnosis of BPH causing bladder outlet obstruction confirmed by clinical symptoms, prostate volume measurement, PSA levels, and uroflowmetry.

Management

• Endoscopic enucleation of the prostate (EEP) is standard surgical treatment regardless of prostate size.
• Laser enucleation (HoLEP or pulsed ThuLEP) preferred due to lower bleeding risk and shorter hospital stay compared to TURP.
• Antiplatelet therapy with aspirin may be continued; clopidogrel paused 7 days preoperatively; anticoagulants paused or bridged as per protocol.

Monitoring & Follow-up

• Perioperative monitoring includes duration of surgery, enucleation time, laser energy used, enucleated tissue weight, catheterization duration, hospitalization length, and postoperative pain scores.
• Postoperative follow-up up to 30 days to assess complications and recovery.

Risks

• Potential bleeding controlled by monopolar electrocautery post-enucleation.
• Management of anticoagulants and antiplatelet agents to minimize bleeding risk.

Patient & Prescribing Data

Men with symptomatic BPH refractory to medical therapy undergoing surgical enucleation.

Pulsed solid-state Thulium: YAG laser offers efficient ablation with less tissue damage and charring compared to Holmium: YAG laser, potentially improving perioperative outcomes.

Clinical Best Practices

• Use of standardized en-bloc enucleation technique by experienced surgeons.
• Preoperative management of antiplatelet and anticoagulant therapies according to institutional protocols.
• Application of monopolar electrocautery for hemostasis after laser enucleation.
• Use of continuous bladder irrigation postoperatively with three-way urinary catheter.
