Rezūm is an in-office, minimally invasive treatment for BPH that uses the natural energy stored in water vapor to reduce excess prostate tissue — without cutting, and typically without affecting sexual function. Most patients return to normal activity within a few days.
What is Rezūm water vapor therapy?
Rezūm treats an enlarged prostate by delivering small, controlled bursts of sterile water vapor directly into the tissue that’s compressing the urethra and causing BPH symptoms. As the vapor cools, it releases its stored thermal energy into the targeted tissue, causing the excess cells to die off and be gradually reabsorbed by the body over the following weeks. The result is a smaller prostate and a wider urinary channel, without removing tissue surgically.
The procedure is FDA-cleared, performed in-office in about 15–20 minutes, and does not require general anesthesia for most patients.
How the procedure works
- A local anesthetic and light oral sedation are used — no incisions, no general anesthesia for most patients.
- A small scope is used to guide the treatment, with no cutting involved.
- Several brief injections of water vapor are delivered to the enlarged tissue, based on the size and shape of your prostate.
- Most patients go home the same day with a temporary catheter, typically removed within about a week.

Who is a candidate for Rezūm?
Rezūm is generally a good option for men whose BPH symptoms — frequent urination, weak stream, incomplete emptying, nighttime waking — haven’t responded well enough to medication, or who want to avoid the side effects some BPH medications carry, including effects on sexual function. Prostate size, symptom severity, and overall health all factor into candidacy, which is why we start with an in-office evaluation before recommending it.
Recovery and what to expect after Rezūm
Most patients return to normal daily activity within a few days, though it can take several weeks for the full symptom improvement to develop as the treated tissue is gradually reabsorbed. A temporary catheter is common for about a week following the procedure. Your care team will walk you through exactly what to expect at your consultation, based on your specific case.
Insurance, cash-pay & financing
Rezūm is covered by Medicare and most major insurance plans when medically indicated, and our team handles prior authorization on your behalf. For patients without insurance coverage, the initial workup (office visit, TRUS, cystoscopy, and UroCuff) is $2,034, and cash pricing for the Rezūm procedure itself is discussed directly with you at your appointment. Financing is also available through CareCredit and other patient financing options, so cost doesn’t have to be a barrier to getting evaluated.
Rezūm frequently asked questions
Is Rezūm painful?
Most patients tolerate Rezūm well. Local anesthesia and light oral sedation are used, and many patients describe mild pressure or urgency during the procedure rather than sharp pain. Some discomfort during the first few days of recovery, particularly while urinating, is common and typically manageable.
How long does the Rezūm procedure take?
The procedure itself typically takes about 15–20 minutes, performed in-office. Including preparation and recovery time before you go home, plan for a longer total visit.
When will I see results after Rezūm?
Rezūm works gradually — the treated tissue is reabsorbed by the body over several weeks, so symptom improvement typically develops over that time rather than immediately. Some men notice initial changes within the first few weeks, with continued improvement over the following months.
Will I need a catheter after Rezūm?
A temporary catheter is common after Rezūm, typically removed within about a week. This allows the treated tissue to heal and swelling to subside before normal urination resumes.
Can Rezūm affect sexual function?
Rezūm carries a notably lower risk of affecting sexual function compared to some other BPH treatments, including certain medications and surgical options. This is one of the most common reasons patients specifically ask about Rezūm — your doctor can discuss your individual risk factors at your consultation.
