What Is Rezūm Water Vapor Therapy? A Simple Guide for Men with Enlarged Prostate

If you get up in the middle of the night to use the restroom or feel like your bladder never fully empties, you're not alone. Millions of older men worldwide suffer from benign prostatic hyperplasia (BPH), also known as an enlarged prostate. Historically, invasive surgery or medicine has been used to treat this issue, but they require lengthier recovery times.

But what if it were possible to retake control in a timely, efficient, and minimally intrusive manner? Rezum Water Vapor Therapy is a new treatment that lasts. Read on to find out what Rezūm therapy is and how it can help men with BPH symptoms feel more at ease and confident again.

What Is Rezum Water Vapor Therapy?

Rezum Water Vapour Therapy is an FDA-approved treatment that uses steam or water vapor's natural energy to eliminate the enlarged prostate tissue that causes BPH symptoms. This novel method offers fewer side effects and a quicker recovery time by using thermal energy to remove tissue efficiently.

Controlled dosages of sterile water vapor are used in the treatment to target particular prostate tissue that is causing problems related to urination. The prostate tissue releases its stored thermal energy when exposed to steam, which kills the cells in the treated area. The prostate shrinks, and the urethra opens over the next few weeks as the body's natural healing mechanisms remove the damaged tissue, improving urine flow.

Purpose

Rezum Water Vapor Therapy's primary goal is to alleviate the symptoms of an enlarged prostate. Conventional BPH treatments may include invasive surgical procedures or medication, which can have serious side effects and lengthen recovery periods. Using steam to target and eliminate extra prostate tissue, Rezūm provides a unique treatment that improves urinary function.

Why choose Rezum Water Vapor Therapy?

Rezum has many benefits if you suffer from BPH.

  • Only a one-day hospital stay is necessary
  • Local anaesthetic is used
  • Long-term BPH medication is not required
  • Maintains Sexual Function
  • Proven Efficiency
  • Rapid Recovery
  • Quick Symptom Relief
  • Long-Term Outcomes
  • Easy, In-Office Process
  • Minimally Invasive
  • FDA Accredited and Reliable
  • Within a month, prostate regression was noticed.

Treatment Process

Rezum Water Vapor Therapy uses a simple yet efficient method to reduce BPH symptoms. Here is a thorough breakdown of the treatment procedure:

Pre-Procedure Preparation

  • Before undergoing RezÅ«m therapy, patients typically complete the following steps:
  • Comprehensive clinical evaluation
  • Prostate imaging, if required
  • Review of medical history and current BPH medications
  • Temporary discontinuation of blood thinners (as advised by the physician)
  • Light fasting before the procedure
  • Local anaesthesia or mild sedation may be provided for comfort

The Procedure in Detail

The Rezum procedure is quick and minimally invasive:

  • A small handheld device is gently inserted through the urethra.
  • Controlled doses of water vapor are released directly into the enlarged prostate tissue.
  • Each steam injection lasts 9 seconds.
  • Most patients require 4-10 injections, depending on prostate size.
  • The total procedure duration is typically 10-15 minutes.
    With no cut
    s or incisions, bleeding is minimal, and healing occurs naturally over time.

Recovery and Aftercare

After the procedure, patients can expect a smooth recovery:

  • A temporary urinary catheter may be placed for 2-3 days.
  • Mild burning, urgency, or discomfort may occur in the early days.
  • Strenuous activities should be avoided for one week.
  • Most individuals return to work within 1-3 days.
  • Symptoms progressively improve as the treated tissue shrinks and the urinary pathway opens.

Do's During Recovery

  • Drink plenty of water.
  • Take prescribed anti-inflammatory medication regularly.
  • Avoid caffeine and alcohol for a few days.

Don'ts During Recovery

  • Avoid heavy lifting.
  • Refrain from sexual activity for 1-2 weeks.
  • Avoid long motorcycle or bicycle rides initially.

Common Side Effects of Rezum Therapy & How to Manage Them

Rezum Water Vapor Therapy is widely recognised as a safe and minimally invasive treatment for BPH, but, as with any medical procedure, some temporary side effects may occur as the body heals. These effects are usually mild, short-lived, and easily manageable with proper care.

  • Mild Discomfort or Swelling: Some men experience temporary soreness or tenderness around the prostate area. This can be effectively managed with prescribed or over-the-counter pain relievers, as recommended by your doctor.
  • Temporary Urinary Retention: Difficulty urinating may occur for a short period after the procedure. In some cases, a catheter may be used briefly to help drain the bladder until normal urination resumes.
  • Urinary Irritation or Urgency: A burning sensation during urination, increased frequency, or sudden urgency is normal in the initial healing phase. These symptoms typically improve within days to weeks.
  • Blood in the Urine (Hematuria): Small traces of blood may appear after the procedure. Staying well-hydrated helps flush the urinary tract and speed up healing.
  • Infection or Inflammation: Although rare, urinary tract infections or prostatitis can occur. These are treatable with antibiotics, so report any persistent fever, pain, or worsening symptoms to your doctor.
  • Temporary Sexual Function Changes: Rezum is designed to preserve sexual function, but a few men may notice short-term changes in ejaculation or erectile function. These typically resolve as recovery progresses.
