The Analysis Of Transurethral Partial Cystectomy In Treatment Of Bladder Tumor By2μm Continuous Wave Laser

Objective:To establish a new surgery method of transurethral partial cystectomy in treatment of bladder tumor by2μm continuous wave laser; To analyze the clinical characteristics of this method and the histopathologic characteristics of bladder tumor’s specimens and to observe the pathologic stages tumour. To observe the efficiency of2μm laser on the edge of the surgery field; To summarize and analyze the clinic characteristics of bladder tumor patients in follow-up periods after the surgery.Methods: From May2011to July2013, we chose patients with bladder tumors treated by2μm laser via transurethral under sacral block. We overview these following variables: operation characteristics, clinic curative effect, pathology staging of the tumor; To summarize and analyze the clinic characteristics of bladder tumor patients in follow-up periods after the surgery.Results: All the patients were tolerated in the operation. The mean operative time Was8-40min. Blood loss in the operation was minimal. No patient experienced an obturator nerve reflection or a hemorrhage after the operation. The tumor,submucosa and all muscular layers Can be resected completely by2μm continuous wave laser transurethral partial cystectomy. No tumor residual Was deteced on the cutting edges. Pathologic staging can be judged correctly. The follow-up periods were between3to15months, There was no recurrence in situ. The survival rate is100%.Conclusions:(1)2μm continuous wave laser for the treatment of bladder tumor is a new safety and efficacy method. Due to the2μm laser can completely excise the whole detrusor muscle layers of bladder,and precisely strip the muscle layer from the outer layer connective tissues, it can get the same clinical result as partial cystectomy. It not only can treatment the superficial bladder tumor efficiently,but also refer to part of invasion bladder tumor.(2)During21am laser partial cystectomy,the tumor and the whole bladder wall at its basal part could be excised completely to obtain a gross specimen. The pathologic staging Can be judged correctly by these specimens. The sections of full-thickness of the bladder wall could be obtained during the pathological examination in order to determine pathological staging and diagnosis. It could be used to observe the therapeutic effects of operations on various grades of tumors and direct the subsequent treatment.(3)Using partial cystectomy by2μm laser,can keep Integrity and less destroied of the tumor.(4)Transurethral partial cystectomy by2μm laser in treatment of bladder tumor. It can not only treat non-muscle-invasive bladder tumors efficiently,but also treat some types of muscle-invasive tumors of the bladder. It has minor influences on the patient’s quality of life. It accords with the principle of evidence-based medicine.
