GreenLight Laser Therapy is a minimally invasive surgical option for benign prostatic hyperplasia (BPH) that combines the effectiveness of the traditional surgical procedure known as transurethral resection of the prostate (TURP), but with fewer side effects, shorter catheterization and quicker, less painful recovery times. GreenLight Laser Therapy uses laser energy to remove enlarged prostate tissue, resulting in an open channel for urine flow-through and relieves all BPH symptoms. During the procedure, the GreenLight laser surgical system, delivers laser light pulses via a specially designed fiber optic device inserted through a standard cystoscope. The laser light pulses are then directed towards the enlarged prostate tissues. The green-laser quickly and accurately vaporizes the prostatic obstruction - removing the enlarged portions of the prostate without causing significant bleeding. The average operative time is typically under sixty-minutes and once the procedure has been completed, most patients experience immediate symptom relief and a dramatic improvement in symptoms such as urinary flow rate and bladder emptying. More importantly, studies have indicated that those dramatic symptomological improvements are durable, for approximately a five-year follow-on period.
