经尿道膀胱肿瘤电切术(TURBT)目前是非肌层浸润型膀胱肿瘤的主要治疗手段。然而.TURBT术后肿瘤的高复发率一直是临床关注的焦点。因此,在临床上寻找一种新的安全、有效切除非肌层浸润型膀胱肿瘤的方法,获得更准确的肿瘤病理分期,降低术后肿瘤复发率和进展率,显得尤为重要,膀胱肿瘤内镜黏膜下剥离术BT-ESD技术在此应运而生。在推动泌尿外科医学事业 Transurethral resection of the bladder tumor (TURBT) is currently the main treatment for non-myometrial invasive bladder tumors. However, the high recurrence rate of tumors after TURBT has been the focus of clinical attention. Therefore, it is very important to look for a new safe and effective method to resect non-muscle invasive bladder tumor in clinical practice, to obtain more accurate tumor pathological staging and to reduce the postoperative recurrence rate and rate of tumor recurrence. Submucosal dissection BT-ESD technology in this came into being. In promoting urology medical career
