Laser prostatectomy offers a viable alternative to transurethral resection of the prostate (TURP) for benign prostatic obstruction, with comparable symptom improvement but fewer complications. However, re-operation rates were higher with laser treatments.

Area of Science:

  • Urology
  • Minimally Invasive Surgery
  • Laser Technology in Medicine

Background:

  • Symptomatic benign prostatic obstruction (BPO) is prevalent in older men.
  • Transurethral resection of the prostate (TURP) is the standard treatment but carries significant morbidity (up to 20%).
  • Minimally invasive procedures, particularly laser prostatectomy, are emerging as safer alternatives.

Purpose of the Study:

  • To evaluate the therapeutic efficacy and safety of various laser prostatectomy techniques.
  • To compare laser prostatectomy outcomes against the established TURP procedure for BPO treatment.

Main Methods:

  • Systematic review of randomized controlled trials (RCTs) sourced from major databases and expert consultation.
  • Included RCTs compared laser techniques with TURP, involving at least 10 men per arm, with a minimum 6-month follow-up.

  • Extracted data included study design, patient characteristics, adverse events, and clinical outcomes like symptom scores and urinary flow.

    • Main Results:

    • Twenty studies with 1898 subjects compared TURP with contact, non-contact, or hybrid laser techniques.
    • Laser prostatectomy demonstrated comparable improvements in urinary symptoms and flow rates to TURP.
    • Laser treatments resulted in lower rates of transfusions, strictures, and shorter hospitalizations; however, non-contact lasers had higher rates of dysuria, UTI, and retention, with increased re-operation rates overall.

    Conclusions:

    • Laser prostatectomy is a valuable alternative to TURP for managing benign prostatic obstruction.
    • Limitations in study design and sample size prevent definitive conclusions on the optimal laser technique.
    • Insufficient data exists to compare laser techniques with other minimally invasive procedures.
