What is BPH?
Benign prostatic hyperplasia (BPH), also called prostate enlargement, is a noncancerous increase in size of the prostate gland. Symptoms may include frequent urination, trouble starting to urinate, weak stream, inability to urinate, or loss of bladder control. Complications can include urinary tract infections, bladder stones, and chronic kidney problems.
“At Regal Hospital, we specialize in the Water Vapor procedure for BPH — providing patients with effective, minimally invasive comfort and improved quality of life.”
How Rezum Water Vapor Works
Unlike burning or laser resection, Rezum harnesses the natural thermodynamic properties of steam to gently clear the obstruction without harming surrounding nerve bundles.
Targeted Delivery
A specialized sterile delivery device reaches the obstructive prostate lobes via the natural urinary tract under local anesthesia.
9-Second Steam Pulse
Sterile water vapor is injected in precise 9-second intervals. The steam travels uniformly through cell interstices without crossing prostate boundaries.
Phase Change Energy
As vapor condenses back to water, thermal energy is released evenly, gently disrupting only the obstructive prostate cells.
Natural Tissue Clearing
Your body naturally absorbs and clears the treated cells over a few weeks, opening the urethra for unrestricted, smooth urine flow.
Why Choose Water Vapor Therapy

Potential Side Effects of Water Vapor Therapy
Because Rezum uses natural water vapor, adverse effects are typically mild to moderate and resolve spontaneously within a few weeks post-procedure.
Mild Discomfort or Swelling
Patients may feel slight pelvic fullness or perineal pressure for the first few days as treated prostate tissue naturally responds to the therapy.
Temporary Urinary Retention
Transient tissue swelling can briefly narrow the urine passage. A temporary catheter is usually placed for 3 to 5 days to ensure effortless bladder drainage.
Irritation or Urgency While Urinating
A mild burning sensation (dysuria) or urgent sensation when urinating is common during the initial healing phase and subsides steadily.
Blood in the Urine (Hematuria)
Traces of light pink urine or microscopic blood may occur intermittently as the body resorbs the treated prostate tissue.
Infections or Inflammation
A localized urinary tract infection is uncommon and readily controlled with a standard short course of preventive oral antibiotics prescribed by our urologists.
Erectile or Ejaculatory Issues
Unlike surgical resection, clinical studies show zero permanent erectile dysfunction risk and an exceptionally low rate (<4%) of ejaculatory alterations.
Who Has BPH?
Prostate enlargement is an almost universal biological progression as men age. Recognizing symptoms early preserves long-term bladder health.
