Visual laser ablation of the prostate (VLAP) significantly improved symptoms and urinary flow in men with benign prostatic hyperplasia (BPH). This laser treatment offers a safe and effective option for bladder outlet obstruction relief.

Area of Science:

  • Urology
  • Minimally Invasive Surgery

Background:

  • Benign prostatic hyperplasia (BPH) commonly causes symptomatic bladder outlet obstruction (BOO).
  • Visual laser ablation of the prostate (VLAP) is a treatment option for BPH.

Purpose of the Study:

  • To evaluate the efficacy and outcomes of visual laser ablation of the prostate (VLAP) in patients with symptomatic bladder outlet obstruction (BOO) due to benign prostatic hyperplasia (BPH).

Main Methods:

  • Eighty-one patients with symptomatic BPH underwent VLAP using a Neodymium:YAG laser.
  • Post-operative outcomes were assessed at 6 months, including International Prostate Symptom Score (I-PSS), maximal urinary flow rate, and residual urine volume.

Main Results:

  • Mean I-PSS decreased significantly from 20.9 to 5.8.

Related Experiment Videos

  • Mean maximal urinary flow rate increased significantly from 7.9 to 16.4 ml/s.
  • Mean residual urine volume decreased significantly from 88.1 to 15.6 ml. Pressure-flow measurements also showed improvement.

    • Conclusions:

    • Visual laser ablation of the prostate (VLAP) provides a highly significant improvement in symptoms and urodynamic parameters for patients with benign prostatic hyperplasia (BPH).
    • VLAP is a safe and effective treatment for bladder outlet obstruction (BOO) in BPH patients.
