The ureteral avulsion during ureterolithotripsy (URS) occurs due to the sudden movement of the optical device or endoscopic extractor either in its removal or insertion, associated with a probable previous lesion in the ureter wall, causing a vital fragility area. A 52-year-old male patient with, an obstructive calculus of 9 mm was found in the left middle ureter, and a heterogeneous hypervascular nodule located in the right kidney, suggesting neoplasia. During procedure with rigid ureteroscopy with ureteroscope removal, due to the pressure of the device and tissue fragility, there was total ureter avulsion.
输尿管镜碎石术（URS）期间发生输尿管撕脱是由于光学设备或内镜取出器在取出或插入过程中的突然移动，这与输尿管壁先前可能存在的病变相关，从而导致一个重要的脆弱区域。一名52岁男性患者，在左输尿管中段发现一枚9毫米的梗阻性结石，右肾有一个异质性高血管结节，提示肿瘤形成。在进行硬性输尿管镜检查并取出输尿管镜的过程中，由于设备的压力和组织脆弱性，发生了输尿管完全撕脱。
