表浅性膀胱肿瘤常作经尿道切除和膀胱内化疗,但每每复发,小数成为浸润癌。肿瘤常位于三角区和输尿管口附近,有时为了保证完全切除而切去抽尿管口。输尿管肌纤维的切断可引起输尿管口侧方移位、扩张和膀脱壁段输尿管缩短,因而导致继发性膀胱肾返流, Superficial bladder tumors often undergo transurethral resection and intravesical chemotherapy, but each time they relapse, decimals become invasive. The tumor is often located near the triangle and the ureteral orifice, and sometimes the urinary orifice is cut to ensure complete resection. The interruption of ureteral muscle fibers can cause lateral displacement of the ureteral orifice, dilatation, and shortening of the ureter of the bladder wall, resulting in secondary bladder kidney regurgitation.
