Avant Concierge Urology Now Offers Innovative Rezūm™ Water Vapor Therapy to Treat Benign Prostatic Hyperplasia (BPH), or Enlarged Prostate

Minimally Invasive Procedure Provides Lasting Relief Without Surgery or Medication1

Avant Concierge Urology today announced it has added a new treatment option, Rezūm™ Water Vapor Therapy — a minimally invasive in-office procedure for men looking to treat their benign prostatic hyperplasia (BPH), not just the symptoms. Rezūm Therapy uses natural water vapor to reduce the size of the prostate and provide lasting symptom relief from BPH without invasive surgery or the potential side effects of prescription drugs.1 

BPH is a condition in which a man’s prostate enlarges and squeezes the urethra, causing frustrating symptoms such as frequent or urgent urination, a weak or interrupted urine stream, and the need to get up several times a night to urinate. It affects about 50% of men by age 60, and 90% of men by age 85.2

“For years, the primary options for treating BPH were through behavior modifications, medications or invasive surgery,” said Dr. Sijo Parekattil, Medical Director of Avant Concierge Urology. “However, medications may not work for everyone and may have undesirable side effects. With Rezūm Therapy, we’re able to provide relief of BPH for men who want to avoid invasive surgery and implants.”

During Rezūm Therapy, which takes place during one short office visit, natural water vapor is released throughout the targeted prostate tissue. When the steam contacts the tissue and turns back into water, it releases energy, killing the excess prostate cells that squeeze the urethra. Over time, the body’s natural healing response absorbs the dead cells and shrinks the prostate. With the extra tissue removed, the urethra opens, reducing BPH symptoms. 

“As many men get older, their prostate gland enlarges, which may squeeze the urethra and obstruct the flow of urine,” added Parekattil. “Some minimally invasive procedures may only treat BPH symptoms, not the underlying condition. What’s great about Rezūm Therapy is that it does not require general anesthesia, and helps most men see symptom improvement within a few weeks.3* Patients typically return to regular activities within a few days after treatment.3* 

Rezūm Therapy has undergone extensive clinical trials to evaluate the safety and efficacy of the treatment.1 It is now included in the American Urological Association’s BPH treatment guidelines and has four-year follow-up data showing its ability to treat prostates with hyperplasia of the central zone, lateral lobe and/or median lobe.

Rezūm Therapy is currently being used in many leading urology practices throughout the United States and around the world. To date, more than 55,000 patients have been successfully treated with Rezūm Therapy.4
