摘要
非肌层浸润性膀胱癌的标准治疗方式为经尿道膀胱肿瘤电切术(TURBT)辅以膀胱腔内化疗或免疫治疗.TURBT具有创伤小、恢复快、可反复切割等优点,但在安全性与病理精确评估方面存在一定的缺陷.而激光用于膀胱肿瘤时既不会产生闭孔神经反射,又可减少手术出血,目前开展的激光手术多以膀胱肿瘤整块切除术为主,激光因其汽化切割避免了组织炭化的可能,因此剜除的膀胱肿瘤基底部肌层组织得以完整保留,对病理的分级及临床分期有独到的优势.本文综述了激光膀胱肿瘤整块切除术的技术优势、现状与进展.
Abstract
The standard treatment for non-muscle invasive bladder cancer is transurethral resection of bladder tu-mor(TURBT)combined with intravesical chemotherapy or immunotherapy.TURBT has the advantages of less trauma,quick recovery,and repeated incision,but it has some shortcomings in safety and accurate pathological evalu-ation.However,when laser is used for bladder tumor,it will not produce obturator nerve reflex,but also reduce sur-gical bleeding.Currently,laser surgery is mainly carried out in en bloc resection.Due to its vaporization cutting,laser avoids the possibility of tissue charring,so the enucleated basal muscle tissue of the bladder tumor was preserved in-tact,which has unique advantages for pathological grading and clinical staging.This article reviews the technical ad-vantages,current situation and progress of laser en bloc resection of bladder tumor.
