Summary

Laser-induced interstitial thermotherapy (LITT) offers effective long-term relief for benign prostatic hyperplasia (BPH). This minimally invasive treatment significantly improves urinary symptoms and flow rates with rare complications.

Area of Science:

  • Urology
  • Minimally Invasive Surgery
  • Laser Therapy

Background:

  • Benign prostatic hyperplasia (BPH) is a common condition affecting aging men.
  • Traditional BPH treatments can have significant side effects.
  • There is a need for effective, minimally invasive BPH therapies.

Purpose of the Study:

  • To evaluate the long-term efficacy and safety of laser-induced interstitial thermotherapy (LITT) for BPH.
  • To assess the impact of LITT on patient symptom scores and urinary flow rates.

Main Methods:

  • A cohort of 239 BPH patients underwent LITT using specialized laser light guides.
  • The procedure aimed for large-volume coagulation necrosis and tissue shrinkage, preserving the urethra.

Main Results:

  • AUA Symptom Scores improved from 25 to 6 at 1 year post-treatment.
  • Peak urine flow rates increased from 8 mL/sec to 18 mL/sec at 1 year.
  • Complications were infrequent: 12% irritative symptoms, 4% strictures, 7% retrograde ejaculation. No impotence or incontinence reported.

Conclusions:

  • LITT is a safe and effective minimally invasive treatment for BPH.
  • The procedure demonstrates significant long-term improvement in urinary symptoms and flow rates.
  • Retreatment rates were low, with few significant complications observed.
