Laser therapy for benign prostatic hyperplasia: a review of recent developments

Area of Science:

• Urology
• Minimally Invasive Surgery
• Laser Technology

Background:

• Endoscopic laser techniques for benign prostatic hyperplasia (BPH) have evolved significantly over 10-15 years.
• These techniques utilize lasers for diverse procedures like coagulation, incision, vaporization, resection, and enucleation, making generalizations inappropriate.
• The drive for laser techniques stems from the potential for shorter hospital stays and reduced morbidity compared to traditional transurethral resection of the prostate (TURP).

Purpose of the Study:

• To define the various endoscopic laser techniques available for BPH treatment.
• To review developments in laser BPH treatment from July 2001 to July 2002.
• To differentiate between tissue-removing and non-tissue-removing laser procedures.

Main Methods:

• Review of endoscopic laser techniques for BPH.
• Analysis of developments reported between July 2001 and July 2002.
• Categorization of laser procedures based on their mechanism (coagulation, incision, vaporization, resection, enucleation).

Main Results:

• Medium-term data for laser techniques are emerging, though long-term data remain limited.
• Cost-effectiveness and patient subgroup applicability are under investigation for each laser modality.
• Interstitial laser coagulation and visual laser ablation show satisfactory moderate-term results.

Conclusions:

• Several minimally invasive laser techniques demonstrate satisfactory moderate-term efficacy for BPH.
• Holmium laser enucleation of the prostate (HoLEP) and potassium titanyl-phosphate (KTP) laser procedures show promising early results.
• HoLEP is a strong contender to become the "gold standard" for treating large prostates, provided long-term durability is confirmed.
