The application of lasers in urology has expanded due to the development and application of various wavelengths of lasers and improvements in optical fiber performance.Particularly in the areas of benign prostatic hyperplasia,bladder tumors,and urinary calculus,lasers have gradually replaced traditional surgical tools to become standard surgical equipment.Upper urological tract tumors and urinary tract stenosis are two other rapidly developing applications for lasers.An overview of the state of laser application in urology,some clinical issues,and future directions are provided in this review.
