Abstract

Introduction: The American Urological Association (AUA) guidelines state that continuing anticoagulation and antiplatelet agents in routine ureteroscopy (URS) is safe and without increased risk of complications. However, these recommendations are based on small case series; thus, we sought to analyze bleeding-related complications among patients on antiplatelet therapy (APT). Materials and Methods: Overall, 4799 URS procedures performed at our institution between June 2009 and February 2016 were identified. Records were then retrospectively reviewed to confirm APT use and to identify periprocedural complications. Antiplatelet agents evaluated included aspirin (low dose and full dose) and P2Y12 receptor antagonists (clopidogrel, prasugugrel, ticagrelor). Patients were excluded if they were taking a concurrent anticoagulant agent or if additional non-URS procedures were performed. Results: Of 4799 URS procedures, 314 (6.5%) were performed on patients taking APT, of which 234 (74.5%) held APT, 63 (20.1%) continued APT, and 17 (5.4%) continued dual APT. The mean age was 70.1 years, and the majority of patients (69.6%) underwent a stone procedure with a stone-free rate of 80.2%. The overall bleeding-related complication rate was 1.9%, whereas the significant bleeding-related event rate was 1.6% and this did not differ among the groups (p = 0.3). The power to detect a 3% difference in bleeding between the groups was 0.95. Conclusions: Continuing APT in patients on chronic therapy does not appear to pose an increased risk of bleeding-related complications. Our findings support the current AUA guidelines as they relate to APT.
