Application of blue laser side light in the vaporization and enucleation of bladder cancer: a report of 16 cases / 现代泌尿外科杂志

ABSTRACT

【Objective】 To observe the efficacy of blue laser side light in the vaporization and enucleation of non-muscle invasive bladder cancer (NMIBC). 【Methods】 A retrospective analysis was performed on the data of NMIBC patients who received transurethral enucleation of bladder tumor (TURBT) using a 50 W blue laser treatment device. The efficacy and safety of surgery were evaluated by observing the application of blue laser in the treatment of bladder cancer in different locations, operation time, presence of bladder perforation and postoperative urine routine indicators. 【Results】 A total of 16 patients completed the surgery, including 5 cases with multiple bladder tumors, 9 with single bladder tumor, and 2 with lichenoid lesions. The postoperative pathological results showed all of them were NMIBC. The operation time was (10.4±4.7) min, postoperative urinalysis was (689.4±316.7)/μL, and no intraoperative bladder perforation occurred. 【Conclusion】 The lateral infusion mode of 50 W blue laser therapy device can be applied to the surgical treatment of NMIBC. The basal vaporization and enucleation of bladder cancer can be performed under direct vision conditions, and the multi-angle enucleation is suitable for bladder cancer in different positions. The tissue penetration depth of blue laser is shallow, which is conducive to the diagnosis and grading of pathological tissues.
