How is a laser procedure for benign prostatic hyperplasia (BPH) performed?

Marc B. Garnick, MD
Hematology & Oncology
To perform a laser procedure for benign prostatic hyperplasia (BPH), the surgeon begins by guiding a fiber through the urethra to the prostate. This fiber conducts the laser light to the target area. Then the surgeon uses the laser to burn away tissue that obstructs the urine flow. Dead tissue that's not immediately vaporized is later expelled in the urine. This technique destroys prostate tissue with less bleeding than standard transurethral resection of the prostate (TURP), an incision-free surgical procedure that cuts away excess prostate tissue with an electrical loop.
