Laser ablation effectively treats bladder outlet obstruction, with 86% of patients experiencing improved urinary flow. This prostate laser surgery offers comparable outcomes to traditional methods, with modifications enhancing results for larger glands.

Area of Science:

  • Urology
  • Minimally Invasive Surgery
  • Laser Technology

Background:

  • Symptomatic bladder outlet obstruction (BOO) affects many men.
  • Transurethral resection of the prostate (TURP) is a common treatment but has associated morbidity.
  • Laser therapies offer alternative approaches to prostate tissue ablation.

Purpose of the Study:

  • To evaluate the efficacy and safety of Neodymium-doped Yttrium Aluminum Garnet (Nd:YAG) laser ablation for treating symptomatic bladder outlet obstruction.
  • To assess the outcomes of visual laser ablation of the prostate (VLAP) alone and in combination with a limited TURP (TURPETTE) for different prostate sizes.

Main Methods:

  • Fifty-five patients with symptomatic BOO underwent laser ablation using right-angle fibers with Nd:YAG laser energy (60-80 W, noncontact mode).

  • Patients were assessed using American Urological Association (AUA) symptom scores, uroflow studies, and monitoring for revision procedures and catheterization.
  • A modified technique (TURPETTE) was used for larger glands (>40 cm3), involving immediate removal of coagulated tissue after lasing.

    • Main Results:

    • 86% of patients demonstrated improved urinary flow and reduced AUA symptom scores.
    • Perioperative morbidity and complications were comparable to TURP.
    • The combined VLAP and TURPETTE technique facilitated earlier voiding, reduced bleeding, and minimized swelling in patients with larger prostates.
    • 14% of patients required revision procedures for obstruction or bleeding.

    Conclusions:

    • Nd:YAG laser ablation is an effective treatment for symptomatic bladder outlet obstruction, yielding results comparable to TURP.
    • The modified TURPETTE technique offers advantages for managing larger prostates, improving outcomes and patient recovery.
    • Advancements in laser fiber technology and surgical techniques will likely shape the future of laser applications in prostate surgery.
