A laser passed through the scope delivers energy to shrink or remove excess tissue that is preventing urine flow. [7] Different types of prostate laser surgery include: Visual laser ablation of the prostate (VLAP) technique involving the Nd:YAG laser with contact on the prostatic tissue. Photoselective Vaporisation of the Prostate (PVP).
Tube-shunt surgery or drainage implant surgery involves the placement of a tube or glaucoma valves to facilitate aqueous outflow from the anterior chamber. [ 41 ] [ 46 ] [ 47 ] Trabeculopuncture uses a Q switched Nd:YAG laser to punch small holes in the trabecular meshwork.
Ho:YAG lasers have wavelength of 2100 nm (infrared) and are used for medical procedures in urology and other areas. They have qualities of CO 2 and Nd:Yag lasers, with ablative and coagulation effects. [10] Holmium laser use results in smaller fragments than 320 or 365 micron pulsed dye lasers or electrohydraulic and mechanical methods. [11]
This therapy and the laser used to perform it have been in use since 1994. [citation needed] It was developed by Robert H. Gregg II [1] [2] and Delwin McCarthy. In LANAP surgery, a variable free-running pulsed neodymium:yttrium-aluminum-garnet (Nd:YAG at 1064 nm wavelength) is used by a dentist or periodontist to treat the periodontal pocket.
Treatment with Nd:YAG lasers and with Nd:YAG laser passed through a Potassium titanyl phosphate crystal, and with an argon laser has been studied in small clinical trials. [11] Nd:YAG laser has been abandoned due to risks of damaging the colon wall, fibrosis, stricture formation, and recto-vaginal fistula, and severe damage in case of accidents ...
To treat benign prostatic hyperplasia (BPH), Nd:YAG lasers can be used for laser prostate surgery—a form of transurethral resection of the prostate. [17] [18] These lasers are also used extensively in the field of cosmetic medicine for laser hair removal and the treatment of minor vascular defects such as spider veins on the face and legs.
Another transurethral method utilizes laser energy to remove tissue. With laser prostate surgery a fiber optic cable pushed through the urethra is used to transmit lasers such as holmium-Nd:YAG high-powered "red" or potassium titanyl phosphate (KTP) "green" to vaporize the adenoma.
Laser surgery is a type of surgery that cuts tissue using a laser in contrast to using a scalpel. [ 1 ] Soft-tissue laser surgery is used in a variety of applications in humans ( general surgery , neurosurgery , ENT , dentistry , orthodontics , [ 2 ] and oral and maxillofacial surgery ) as well as veterinary [ 3 ] surgical fields.
