Summary

A new interstitial laser coagulation method effectively treats benign prostatic hyperplasia (BPH) using Nd:YAG laser. This minimally invasive technique shrinks prostates, improving urinary flow and reducing symptoms without retrograde ejaculation.

Area of Science:

  • Urology
  • Medical Technology
  • Laser Surgery

Context:

  • Benign prostatic hyperplasia (BPH) is a common condition in aging men.
  • Current treatments for BPH can have significant side effects.
  • A need exists for effective, minimally invasive BPH therapies.

Purpose:

  • To introduce and evaluate a novel interstitial laser coagulation (ILC) method for BPH treatment.
  • To assess the efficacy and safety of ILC using Nd:YAG laser and a new light guide system.

Summary:

  • The ILC method utilizes Nd:YAG laser irradiation delivered via a specialized light guide to coagulate prostate tissue.
  • In vitro and in vivo studies demonstrated homogeneous tissue coagulation and subsequent scar formation with shrinking.
  • Clinical application in 27 patients showed significant improvements in peak flow rate, reduced residual volume, and decreased prostate weight.

Impact:

  • The ILC procedure offers a promising minimally invasive treatment option for BPH.
  • The technique resulted in significant symptom relief and functional improvement in patients.
  • No cases of retrograde ejaculation were reported in sexually active patients, suggesting preserved sexual function.
