钬激光是以钬－钇－铝石榴石为激活媒质的新型固体激光器，能有效切割软组织，粉碎坚硬的结石，并且可以通过直径４００μｍ的光导纤维经内窥镜行腔内泌尿外科疾病治疗。应用钬激光经腔内治疗泌尿外科疾病４０例，膀胱肿瘤３６例（共５９枚肿瘤，均为Ｔ１～Ｔ２期，Ｇ１～Ｇ２级。肿瘤大小：０．５～４ｃｍ），膀胱结石４例（结石大小：１～２．５ｃｍ），输尿管囊肿１例，其中１例膀胱肿瘤患者合并膀胱结石。４０例手术全部成功。钬激光可以近乎“无血”切割、汽化膀胱肿瘤，术中无膀胱穿孔、大出血、闭孔神经反射等并发症，术中无脱落癌细胞，术后创面多点活检无残留癌细胞，创面规整，无需改为开放手术，术后随诊平均１６．５月，复（再）发率：５．６％。钬激光治疗膀胱结石４例，其中粉碎尿酸结石最容易，激光粉碎结石时间快（２～１７．７ｍｉｎ），钬激光去盖减压治疗输尿管囊肿效果很好。认为钬激光切割、汽化、止血效果好，且可以粉碎结石，可以完全有效经腔内治疗泌尿外科疾病。值得临床推广应用。
Holmium laser is a new type of solid-state laser based on holmium-yttrium-aluminum garnet. It can effectively cut soft tissue, crush hard stones and can be treated endoscopically with endoscopic urotracheal diseases through optical fibers with a diameter of 400μm. Holmium laser treatment of endoscopic urological diseases in 40 cases, 36 cases of bladder tumors (a total of 59 tumors, T1 ~ T2, G1 ~ G2 grade. Tumor size: 0.5 ~ 4cm), bladder stones in 4 cases Stone size: 1 ~ 2.5cm), ureter cyst in 1 case, 1 case of bladder cancer patients with bladder stones. All 40 surgeries were successful. Holmium laser can be almost “without blood” cutting, vaporization of bladder cancer, intraoperative bladder perforation, bleeding, obturator nerve reflex and other complications, surgery without shedding of cancer cells, postoperative wound biopsy without residual cancer cells, wound regular , No need to change to open surgery, the average follow-up of 16.5 months, recurrence rate: 5.6%. Holmium laser treatment of bladder stones in 4 cases, of which the most easy to crush uric acid stones, laser crushing stones fast (2 ~ 17.7min), holmium laser cover decompression ureteral cyst is very good. That holmium laser cutting, vaporization, hemostatic effect, and can crush stones, can be completely and effectively treated by endoscopic urological diseases. Worthy of clinical application.
