Rezum – Water Vapor Therapy for BPH (Enlarged Prostate)
Rezum therapy for enlarged prostate, a system manufactured by Boston Scientific, is a method in which steam energy is used to cut (or remove) a specific part of the prostate that is enlarged and causing BPH-related symptoms.
How is it done?
Resum therapy is administered using a handpiece and a radio frequency generator. The procedure may be performed in an operating room or procedure room under general or local anesthesia (usually a urethral lignocaine gel) with sedation in selected cases. Each steam injection takes nine seconds to deliver and is systematically placed in the prostatic transition zone, with the number of injections corresponding to the overall volume and endoscopic appearance of the prostate.
The larger and more occluded the prostate, the more injections must be given to the patient to ensure an effective procedure. More importantly, while the size of the gland should be considered, the shape of the gland is not an issue, including the presence of a median or middle lobe. After the injections are completed, a urethral catheter is placed for three to five days to allow the inevitable post-procedure swelling of the prostate to settle. Regardless of the type of anesthetic used, the patient can usually go home on the day of the procedure.

What is benign prostatic hyperplasia?
Benign prostatic hyperplasia (BPH) is a condition in which a man’s prostate enlarges and blocks the flow of urine. Causes annoying symptoms, including frequent urination; weak, interrupted urine stream; difficulty starting and stopping urination; feeling a sudden urge to urinate; inability to urinate when necessary; and lack of control over urination.
How common is it?
BPH is more common in older men, affecting about 50% of men by age 60 and 90% of men by age 85.

How does Rezūm Therapy work? How is the procedure?
- During Rezūm Therapy, natural water vapor is released throughout the targeted prostate tissue. When the steam comes into contact with the tissue and turns back into water, all the stored energy is released and kills the excess prostate cells. Over time, the body’s natural healing response absorbs dead cells and shrinks the prostate. When the extra tissue is removed, the urethra opens up and relieves BPH symptoms.
- Without the need for a permanent implant, this natural treatment option removes excess BPH tissue and thus treats not only the symptoms but also the disease.
- Rezūm Therapy can be administered in a doctor’s office, clinic, or other outpatient setting. It can be done under oral sedation or local anesthesia. Options are available to maximize comfort during the procedure, which will be determined by the physician.
What research has been done?
- Rezūm Therapy has undergone extensive clinical trials to evaluate the safety and efficacy of the treatment. It is now included in the American Urological Association’s BPH treatment guidelines and has four years of follow-up data demonstrating its ability to treat prostates with central region, lateral lobe, and/or median lobe hyperplasia.
Does it have any side effects?
- All treatments have inherent and associated risks. The Rezūm System is designed to relieve symptoms and blockages and reduce prostate tissue associated with BPH. Indicated for men ≥ 50 years of age with a prostate volume of 30cm3 ≤ 80cm3. The Rezūm System is also indicated for the treatment of prostate with central region and/or median lobe hyperplasia. Potential risks include, but are not limited to, painful urination (dysuria), blood in the urine (hematuria), blood in the semen (hematospermia), decreased ejaculatory volume, suspected urinary tract infection (UTI), and urinary frequency, retention, or urgency. . Patients should talk to their doctor about the benefits and risks before moving forward with any treatment option.

Main points
- Promising new minimally invasive surgical treatments (MISTs) for the management of symptomatic BPH have increased to reduce the risk of adverse events, particularly related to preservation of sexual function.
- The Rezum system is a new minimally invasive treatment for symptomatic BPH using transurethral water vapor thermal energy.
- It represents a safe and effective procedure with permanent relief, preservation of sexual function, low complication rate and short recovery time in LUTS.
The Rezum System is a new minimally invasive treatment for benign prostatic enlargement using transurethral water vapor thermal therapy. It appears to be an effective, safe and cost effective procedure. Recent data demonstrate its versatility by preserving sexual function even in catheter-dependent patients with large prostates or median lobes. This procedure can be performed in an office or outpatient setting under local anesthesia, which reduces anesthesia risks and recovery time.

Procedure Day

Its treatment is a minimally invasive procedure performed in the office and does not require general anesthesia. Patients can leave their homes and return to their normal activities within a few days.
Symptom Improvement Clinical studies show that most men experience symptom relief two weeks after treatment with Rezūm Therapy and that maximum benefit can occur within three months.
