Although general guidelines exist directing the management of new/novel oral anticoagulants (NOACs) in the perioperative period for open/endoscopic procedures, no consensus exists for those patients being considered for shockwave lithotripsy (SWL). To gauge current practice, we administered a survey to the international endourologic community.


A web-based survey was sent to current Endourological Society members. Respondents were asked whether they would consider SWL in patients receiving NOACs, and if they used SWL how these agents were managed perioperatively. Respondents were also asked which physicians in the patients’ circle of care managed the discontinuation and reinstitution of the drugs.


There were 165 respondents from 27 countries. Approximately 92.7% of urologists had access to SWL but only 53.4% indicated they would offer SWL to patients receiving NOACs. Among these urologists, 63.3% relied on internal medicine/hematology/cardiology colleagues to counsel patients on the discontinuation of NOACs pretreatment, whereas the majority (64%) handled the resumption guidance themselves. There was wide variability in the management of NOACs before lithotripsy, with discontinuation varying from 2 to 7 days. Resumption was more consistent, ranging from 1 to 2 days or when hematuria resolved. None of the respondents reported knowledge of adverse effects such as perinephric hematomas or cardiovascular morbidity.


A large percentage of globally surveyed endourologists do not offer SWL to patients who are taking NOACs. Among those that do offer SWL, there seems to be a absence of consensus on optimal duration of discontinuation, suggesting a need to establish evidence-based guidance to optimize patient outcomes.
