What is the UroLift® System?
Treatment with the UroLift® System uses a minimally invasive approach that provides rapid relief and recovery of BPH symptoms.
It is an earlier treatment option can get men off BPH medications and avoid major surgery.

How Does The UroLift® System Work?
The UroLift® System uses a revolutionary approach to treating BPH that lifts and holds the enlarged prostate tissue so it no longer blocks the urethra. It is the only available BPH treatment performed by a urologist that does not require heating, cutting, or removal of the prostate tissue. The procedure is typically performed using local anesthesia in a physician’s office or ambulatory surgery center. Patients typically return home the same day without a catheter.1
