2 micron laser: a new weapon in the minimally invasive treatment of prostate enlargement Benign prostatic hyperplasia (BPH) is a disease that seriously affects the health and quality of life of older men, and although medication can slow the progression of the disease, a significant number of patients still require surgical treatment. The 2-micron laser is a continuous wave, high-power laser with a wavelength of 2 microns, working within 2 mm of the laser fiber and causing no damage to tissues outside of 2 mm. The 2 micron laser has a penetration depth of only 0.3 mm in the tissue, leaving a coagulated layer of only 1 mm after removing the hyperplasia. The difference between 2 micron laser treatment of prostate enlargement and traditional methods of treating prostate enlargement: The traditional surgical methods of treating prostate enlargement are open prostate removal and transurethral resection of the prostate (TURP), although TURP is currently the “gold standard” for treating BPH, but TURP still has some drawbacks and shortcomings. The TURP procedure is similar to peeling potatoes, each knife can only cut off a small piece of hyperplastic tissue, the larger the tissue, the more knives are removed, the longer the surgery time, and the constant electrocoagulation to stop the bleeding, the exposed blood vessels of the cut wound, the flushing fluid is easily absorbed by the body in large quantities, resulting in water poisoning and life-threatening. Also, urinary incontinence and hemorrhage are serious complications. For the treatment of large volume BPH, open prostatectomy is still used by some hospitals, but open prostatectomy is more difficult to stop bleeding and bleeding, and the surgery is more damaging to the surrounding tissues and organs, and postoperative complications such as bladder spasm and incision infection are likely to occur, and patients suffer more. 2 micron laser surgery features: ① can quickly and effectively remove hyperplastic tissue ② minimal bleeding during and after surgery ③ short surgery time ④ safer, less complications ⑤ indwelling catheterization time, short hospital stay ⑥ can treat elderly patients, prostate gland size is not limited ⑦ good clinical results The device is also suitable for the treatment of bladder tumors and urethral strictures, for bladder tumors growing on the lateral wall of the bladder and patients with a history of heart The 2 micron laser is an excellent indication for bladder tumors and urethral strictures, and for patients with a history of heart stenting.
