RIRS using a flexible and navigable suction ureteral access sheath and thulium fiber laser in a patient taking anticoagulants with multiple large kidney stones. Clinical case.

Abstract

Percutaneous nephrolithotomy is one of the modern methods for treating kidney stones larger 2 cm. When anticoagulation therapy cannot be stopped, retrograde intrarenal surgery (RIRS) is recommended. We report a case of RIRS using flexible and navigable suction ureteral access sheath (FANS-UAS) and Thulium fiber laser (TFL) in a patient with multiple large kidney stones who could not be stopped on anticoagulant therapy. The surgery was successful and without complications. RIRS using FANS-UAS and TFL in this group of patients has high efficacy and safety.
