Sudden cardiovascular collapse during the TUL procedure: A case series.

Although ureteroscopy is a minimally invasive procedure, there have been reports of some minor and major complications, from self-limited to complicated events such as ureteral avulsion, urosepsis, and even death due to cerebrovascular accidents and deep vein thrombosis. Herein, we aim to report seven patients who presented with cardiovascular collapse during ureteroscopy in a 19-year period from January 2002 to January 2021.
