June 27, 2014 - UGofSC recently acquired the revolutionary Olympus PlasmaButton™ vaporization technology for treatment of benign prostatic hyperplasia (BPH), or enlarged prostate. This technology provides a new, virtually bloodless treatment option for BPH.  If left untreated, BPH can impact quality of life and cause complications such as severe urinary tract infections, urinary retention or even renal failure. Ultimately, three out of 10 men suffering from BPH have to undergo surgery.


PlasmaButton technology gently vaporizes enlarged prostate tissue with a small button-shaped device using low-temperature plasma energy, while minimizing damage to surrounding healthy tissue.  This constrasts with conventional transurethral resection of the prostate (TURP), where prostate tissue is removed using cutting loops using high temperatures.

If you would like to be evaluated to find out if you are a candidate for these innovative new treatment. please call our office for an appointment with Dr. Kowalczyk.
