Interstitial laser coagulation treatment for benign prostatic hyperplasia

摘要

A method of treating benign prostatic hyperplasia employs the steps of inserting a diffusing light guide into a prostrate lobe and providing laser power to the diffusing light guide in order to necrose surrounding tissue. The diffusing light guide can be inserted into the central or lateral prostrate lobes by inserting a needle and a trocar transperineally into the middle of the lateral lobe, removing the trocar, inserting the diffusing light guide, and monitoring the position of the needle, trocar, and diffusing light guide using ultrasound. The diffusing light guide can also be inserted into the central or lateral prostrate lobes transurethrally and positioned with the aid of an urethroscope.
