Summary
Thulium:YAG (Tm:YAG) vapoenucleation effectively treats benign prostatic obstruction in large prostates, showing significant volume reduction and symptom improvement with a manageable complication rate over 12 months.
Area of Science:
- Urology
- Minimally Invasive Surgery
- Laser Technology
Background:
- Benign prostatic obstruction (BPO) is common in aging men.
- Thulium:YAG (Tm:YAG) vapoenucleation offers a minimally invasive approach.
- Its efficacy in large prostates requires further validation.
Purpose of the Study:
- To evaluate the safety and efficiency of Tm:YAG vapoenucleation.
- To assess its performance in prostates ≥ 80 cc.
- To confirm size independence for BPO treatment.
Main Methods:
- 90 consecutive patients with BPO and large prostates underwent Tm:YAG vapoenucleation.
- A 90 W Tm:YAG laser and mechanical morcellator were used.
- Data collected included perioperative and 12-month follow-up, with complication assessment.
Main Results:
- Significant reductions in prostate volume (86%) and PSA (88%) were observed.
- International Prostate Symptom Score and quality of life improved significantly (p <0.001).
- Complications were manageable, with low rates of transfusion, incontinence, and reoperation for stricture.
Conclusions:
- Tm:YAG vapoenucleation is a safe and effective treatment for BPO in large prostates.
- The procedure achieves complete adenoma removal, demonstrating size independence.
- It offers a promising minimally invasive option for BPO management.
