A prostatectomy is the surgical removal of all or part of the prostate gland. Abnormalities of the prostate, such as a tumour, or if the gland itself becomes enlarged for any reason, can restrict the normal flow of urine along the urethra. This method utilizes laser energy to remove tissue. With laser prostate surgery a fibre optic cable pushed through the urethra is used to transmit lasers such as holmium-Nd: YAG high powered “red” or potassium titanyl phosphate (KTP) to vaporize the adenoma.
The specific advantages of utilizing laser energy rather than a traditional electrosurgical TURP is a decrease in the relative blood loss, elimination of the risk of TUR syndrome, the ability to treat larger glands, as well as treating patients who are actively being treated with anti-coagulation therapy for unrelated diagnoses.
