The GreenLight PV Laser System is a patented green light laser that provides the energy to perform the PVP procedure. A thin fiber is inserted into the urethra through a cystoscope, an instrument that allows the doctor to examine the bladder and prostate. The fiber delivers green laser energy that quickly vaporizes and precisely removes enlarged prostate tissue. Dr James Tan is able to safely view and control the treatment area, tailoring it to your individual anatomy and needs. Because the tissue is vaporized and removed, a wide-open channel is created. Natural urine flow is immediately restored and urinary symptoms are relieved.
