Discover Rezum Water vapor therapy, a safe and effective non-surgical treatment for enlarged prostate (BPH) that helps men urinate normally again without major surgery.
Understanding Enlarged Prostate (Benign Prostatic Hyperplasia – BPH)
The prostate gland, part of the male reproductive system, produces seminal fluid and surrounds the urethra.
As men age—typically after age 50—the prostate may enlarge due to cell overgrowth, leading to compression of the urethra.
Common symptoms include:
- Weak urine stream
- Difficulty starting urination
- Frequent nighttime urination (nocturia)
- Urge incontinence
- Inability to empty the bladder completely
What Is Rezum Water Vapor Therapy ?
Rezum is an advanced, minimally invasive technology that uses natural water vapor to shrink the prostate.
During the procedure, the doctor inserts a thin instrument with a small camera through the urethra and releases steam directly into the enlarged prostate tissue.
The steam destroys excess prostate cells, which are naturally absorbed by the body over time—allowing the urethra to open and restore normal urination.
Most patients notice improvement within 2 weeks, with optimal results seen at 3 months after treatment.
Who Is Rezum Water vapor therapy Suitable For?
Rezum Water vapor therapy is ideal for:
- Men who experience side effects from prostate medication (such as reduced sexual function or dry ejaculation).
- Patients who wish to avoid major surgery.
- Individuals diagnosed with mild to moderate BPH who seek a faster recovery option.
Pre-Procedure Evaluation
Before the procedure, your urologist will conduct:
- Ultrasound: to determine prostate size.
- PSA and Urine Tests: to rule out infection.
- Medication Review: especially for those on anticoagulants, which may need to be paused.
On the Day of the Procedure
- The procedure takes only 10–15 minutes.
- Performed under mild sedation, no general anesthesia required.
- A temporary catheter will be inserted to aid urination during initial swelling.
Advantages of Rezum Water Vapor Therapy
- Short treatment time (10–15 minutes)
- Safe, minimally invasive, and fast recovery
- No need for general anesthesia
- Long-lasting results without repeated treatment
- No impact on sexual or erectile function
- Medication can often be discontinued afterward
