Bleeding Risk of Cystoscopy with GreenLight Ablation of Prostate

Bleeding Risk Profile

  • GreenLight PVP demonstrates shorter catheterization and hospitalization times, as well as lower transfusion and clot retention episode rates compared to TURP 1
  • Evidence from case series shows that the 80-W, 120-W, and 180-W GreenLight lasers are safe in high-risk patients and in those receiving anticoagulation 1
  • The hemostatic properties of GreenLight laser make it particularly suitable for patients with increased bleeding risk 2

Comparison with Other Techniques

  • The 180-W PVP is noninferior to TURP in terms of perioperative complications 1
  • The reoperation rate after 180-W XPS laser was comparable with that after TURP but was significantly higher after 120-W HPS laser (11% vs 1.8%; p = 0.04) 1
  • An RCT comparing PVP with HoLEP in patients with prostate volume >60 ml showed comparable symptomatic improvement, but PVP had a 22% conversion rate to TURP 1

Pitfalls and Caveats

  • The 22% conversion rate to TURP when using PVP for prostates >60ml should be considered when planning the procedure 1
