Abstract

Purpose: To examine the complications and functional outcomes of high-risk patients on antithrombotic therapy (ATT) treated with photoselective vaporization of the prostate (PVP) using the Greenlight (GL) XPS-180 system.

Methods: A retrospective analysis of prospectively maintained institutional database was performed. Men with symptomatic LUTS related to BPH were treated with 523-nm GL PVP using the XPS-180 W system. They were stratified according to ATT status: group 1 (control group), group 2 (acetylsalicylic acid), group 3 (antiplatelet agents other than acetylsalicylic acid) and group 4 (anticoagulation agents). Postoperative adverse events at 30- and 90-days were prospectively recorded. Complications were stratified according to the Clavien-Dindo classification. Additionally, functional outcomes (IPSS, Qmax and PVR) were analyzed up to 48 months of follow-up after surgery. Multivariable logistic regression analyses were used to predict the effect of ATT on serious bleeding-associated complications that was defined as the sum of patients with hematuria Clavien grade ≥ 2, patients requiring transfusions and patient with postoperative hemoglobin drop ≥ 15 g/dl.

Results: 274 (63%), 87 (21%), 24 (6%) and 37 (9%) patients were included in groups 1, 2, 3 and 4, respectively. Patients on antiplatelet (group 3) and anticoagulant medication (group 4) were older (median age 60 vs. 68 vs. 77 vs. 76 years, p < 0.001) and had more comorbidities (ASA 3-4: 9.5 vs. 27.6 vs. 66.7 vs. 64.9%; p < 0.001) than their counterparts. The overall 30-day complications rates were 31, 28.7, 45.8 and 45.9% of patients included in groups 1, 2, 3 and 4, respectively (p = 0.4). Hematuria Clavien 1 events (p < 0.001), readmissions rates (p = 0.02), length of post-operative hospital stay (p < 0.001) and catheterization time (p < 0.001) were significantly higher in patients on antiplatelet and anticoagulation medication. In multivariable analyses, ATT status was not a predictor of serious bleeding events after surgery (p > 0.5). Finally, functional outcomes were significantly improved accross the four groups.

Conclusion: GL PVP is safe and effective in treating high-risk patients on ATT. Although serious bleeding complications are rare and equivalent with non-high-risk patients, patients on antiplatelet and anticoagulation medication should be counseled on the increased risk of minor bleeding events and readmissions rates at 30 days after surgery.
