Rezum: What to Expect

REZUM therapy is a minimally invasive, in-office, and non-surgical procedure to shrink an enlarged prostate due to benign prostatic hyperplasia or BPH. Heat generated by radiofrequency waves is delivered to the prostate through a needle that emits water droplets that generate steam. This allows for a rapid treatment that has the ability to expand but will not go beyond the anatomical boundary of the prostate itself. The REZUM starts with a transrectal ultrasound which will be used to take a picture of the prostate, determine its dimensions, and inject lidocaine as local anesthesia. This is a very well-tolerated step akin to numbing before a dental procedure and is very quick. The patient will then be repositioned with legs in stirrups and the REZUM can commence.
