How long does it take for Rezūm to work?

Relief is gradual. Many men have a catheter for several days to a couple of weeks and temporary worsening first, with meaningful improvement building over about two to three months as the treated tissue shrinks.

Does Rezūm preserve sexual function?

Generally yes — Rezūm is chosen largely because it tends to preserve ejaculation and erectile function, unlike TURP, which usually causes retrograde ejaculation.

Who is a candidate for Rezūm?

Men with moderate prostate enlargement who want to protect sexual function and avoid the operating room. Unlike UroLift, Rezūm can treat a median lobe. Very large prostates are usually better treated with HoLEP or simple prostatectomy.

What are the downsides of Rezūm?

The gradual timeline, a temporary catheter, irritative urinary symptoms and blood in the urine or semen for a while, and the possibility of needing another treatment later if symptoms return.

Is Rezūm better than UroLift?

Neither is universally better. Rezūm can treat a median lobe and works gradually with steam; UroLift gives quicker recovery but needs the right shape (no median lobe). The better choice depends on your anatomy and how quickly you need relief.

What does Rezūm cost?

It depends on whether it is done in the office or a facility and on your insurance. It is widely covered for symptomatic BPH — confirm pre-authorization and ask for a written estimate and how it will be billed.

Rezūm for BPH: Steam Therapy Candidacy, Recovery & Cost

The short answer

Rezūm uses water vapor (steam) to shrink obstructing prostate tissue in a short office procedure, and it usually preserves ejaculation and erections. Relief is gradual — most men improve over several weeks to a few months, often after a brief period with a catheter and temporary worsening. It suits moderate enlargement when protecting sexual function matters.

Rezūm versus the alternatives

Rezūm

Moderate enlargement (including a median lobe), preserving sexual function, accepting gradual relief.

How many weeks until I should expect improvement, and how long will I need a catheter?

UroLift

Smaller prostate with no median lobe; faster recovery but cannot treat a median lobe.

Does my anatomy qualify for UroLift, or is Rezūm the better steam-vs-implant choice?

TURP / HoLEP

More immediate and durable relief; usual trade-off of retrograde ejaculation.

Is my prostate too large for an office option like Rezūm?

How Rezūm works and who it fits

During Rezūm, a urologist delivers a few seconds of water vapor into the obstructing prostate tissue through the urethra. The treated tissue is gradually reabsorbed by the body over the following weeks, opening the channel. It is typically an office procedure.

Rezūm is a good fit for men with moderate enlargement who want to preserve ejaculation and erections and prefer to avoid the operating room. Unlike UroLift, it can treat a protruding median lobe — a meaningful advantage for that anatomy. Very large prostates are usually better treated by enucleation (HoLEP) or simple prostatectomy.

The realistic timeline to relief (the honest part)

Rezūm does not work overnight. Most men need a catheter for a few days to a couple of weeks afterward, and many notice temporary worsening of urinary symptoms before they improve. Meaningful relief usually builds over roughly two to three months as the treated tissue shrinks.

If you need fast, definitive relief — for example, because you are in retention — a resective procedure may suit you better. Setting this expectation upfront is what separates an honest discussion from a sales pitch.

Sexual function, downsides, and retreatment

A major reason men choose Rezūm is that it generally preserves ejaculation and erectile function, unlike TURP. Downsides include the gradual timeline above, the temporary catheter and irritative symptoms, blood in the urine or semen for a while, and the possibility of needing a repeat treatment or another procedure later if symptoms return.

Rezūm versus UroLift, and cost

Both Rezūm and UroLift are office-based and ejaculation-sparing, which is why patients compare them. The practical difference is anatomy and mechanism: UroLift physically holds tissue aside and needs the right prostate shape (no median lobe), while Rezūm shrinks tissue with steam and can treat a median lobe but works gradually. Cost depends on setting and insurance — ask whether it is billed as an office procedure and get a written estimate.

There is no single best enlarged-prostate procedure. The right choice depends on prostate size, how much you want to protect ejaculation, whether you take blood thinners, how durable a result you need, and your anesthesia preference. A urologist who offers more than one option can compare them for your anatomy.

What shapes Rezūm cost and fit

Office vs facility setting: Rezūm is frequently done in the office under local anesthesia or light sedation, which usually costs less than a hospital procedure — but the setting varies by practice.
Prostate size and shape: Rezūm fits moderate enlargement and can treat a median lobe (which UroLift cannot). Very large prostates are usually better served by HoLEP or simple prostatectomy.
Catheter and recovery time: Many men need a catheter for several days afterward and have temporary worsening before improvement. Plan for that period when comparing the 'cost' of each option.
Insurance coverage: Rezūm is widely covered for symptomatic BPH, but confirm pre-authorization and whether it is billed as an office or facility procedure.
