Rezum water-vapor therapy — for the prostates lifts can't fix.
Brief 9-second bursts of water vapor (steam) shrink the enlarged prostate from the inside. Because it actually reduces tissue volume, Rezum works where implant- and suture-based lifts reach their limit — larger glands over 80g and middle-lobe enlargement. 15–30 minutes, local anesthesia with sedation, same-day discharge, sexual function preserved in 90%+ of men.
“When a prostate is large or has a middle lobe pushing into the bladder, holding it open isn't enough — you have to remove volume. Rezum does exactly that with steam, gently and without an incision. It's the procedure I reach for on the harder BPH cases.”
— Dr. Moon Hyeon-chang, Director
The case for vapor over a lift.
UroLift and Progator hold the prostate open. Rezum shrinks it — which is why it's the answer for the cases a lift can't reach.
Larger prostates (80g+)
Steam ablation reduces actual gland volume, so it keeps working on prostates from 50g to 100g+ — sizes where mechanical lifts lose their effect.
Middle-lobe enlargement
A middle lobe pushing up into the bladder is the classic "lift won't help" pattern. Rezum treats it directly — its single biggest advantage.
Highest effectiveness in its tier
~75% IPSS improvement — modestly higher than UroLift or Progator (~70%) — while still keeping sexual function in 90%+ of men.
What Rezum actually delivers.
Honest numbers — including the parts that take patience.
How the vapor treatment works.
Steam, precisely placed
Through a cystoscope, a fine needle delivers 6–10 brief 9-second bursts of sterile water vapor into the enlarged tissue. The urethral lining is actively protected throughout.
The body does the shrinking
The vapor's thermal energy ablates excess tissue. Over the following weeks your body gradually resorbs it, the gland shrinks, and the channel opens — a real volume reduction, not just a hold-open.
Brief, outpatient, then a catheter
15–30 minutes under local anesthesia with sedation, same-day discharge. A catheter stays in for 2–3 days while early swelling settles, and is removed here before you fly home.

Rezum's edge is size and middle lobe — it works where lifts can't. The trade-off is a short catheter and a slower build to full effect. All procedures are ₩10,000,000 (≈ US$6,600), so the choice is about your anatomy, not price.

What you accept in return.
Rezum's power comes with two real trade-offs. We'd rather you know them now than be surprised in Busan.
A 2–3 day catheter
- Early vapor swelling means a catheter is needed for 2–3 days
- Removed here at the clinic before you fly home
- Day and night drainage bags provided; bladder-spasm medication keeps it comfortable
- This is why we plan a slightly longer Busan stay than for a lift
A gradual, 3-month build
- Unlike a lift's immediate effect, Rezum works as the body resorbs ablated tissue
- Mild improvement by week 1–2, clear gains by month 1–2
- Full effect around month 3 — most men are off BPH medication by then
- We track your IPSS remotely so you're never guessing
Is Rezum right for you ?
Around 35% of our procedural BPH patients choose Rezum — usually the ones with a larger or middle-lobe prostate. The honest version of who fits.
A good Rezum candidate
- Prostate volume 50–100g+ (larger glands)
- Significant middle-lobe enlargement
- IPSS 8 or higher with bothersome symptoms
- Medication failed or you want to stop it
- Wants to preserve sexual function
- Can accept a 2–3 day catheter and a 3-month build
Better suited to another option
- Smaller prostate under 30–40g, no middle lobe → UroLift or Progator
- Wants no catheter / immediate effect → a lift
- Acute urinary retention or bladder stones
- Known prostate cancer (treat the cancer first)
- Active prostatitis (pain, not flow)

What the ₩10,000,000 covers.
One all-inclusive direct-pay package — the same FDA-approved Rezum system used at leading US centers.
Rezum — all-inclusive
Itemized English receipts available on request. Standalone BPH work-up (testosterone, PSA, urinalysis, ultrasound) is ₩600,000 if you only want diagnostics first.
From procedure day to month three.
Walk out the same day
15–30 minute procedure, then discharge with a catheter in place. Mild discomfort and pink urine are expected and controlled with prescribed medication.
Light days while swelling settles
Catheter stays in with day and night drainage bags. Light walking, plenty of water, antibiotics and bladder-spasm medication on schedule.
Removed before you fly home
The catheter is removed here at the clinic. Most international patients fly home around day 5 and return to desk work within the first week.
Steady improvement
As the body resorbs the ablated tissue, the gland shrinks. Stream strengthens, night-time trips drop, urgency eases — clear, building gains.
Full effect & review
Peak improvement is usually reached by month three, when most men are off BPH medication. We review your IPSS remotely and discuss next steps only if needed.

Before you fly to Busan.
Rezum injects brief 9-second bursts of water vapor — sterile steam at about 103°C — into the enlarged prostate through a needle in a cystoscope. The vapor's heat ablates excess tissue while the urethral lining is protected. Over about three months the body resorbs the treated tissue, the gland shrinks and urine flows more freely.
Implant- and suture-based lifts hold the prostate open, which works best on smaller glands under 80g. Rezum actually reduces prostate volume, so it keeps working on larger prostates and on middle-lobe enlargement — the patterns where lifts run out of room. The trade-off is a short catheter and a slower build to full effect.
More than 90% of Rezum patients keep normal erections and ejaculation. A small share (about 5–10%) notice some retrograde ejaculation. For context, UroLift preserves function in essentially 100% of men, while common BPH medication causes retrograde ejaculation in 30–60% — so Rezum sits very favorably for a volume-reducing treatment.
Typically 2–3 days. It's needed because the vapor causes brief swelling before the tissue is resorbed. The catheter is removed here at the clinic before you fly home, and day/night drainage bags plus bladder-spasm medication keep it manageable — most men adapt within hours.
Gradually, over about three months — this is the patience part. Weeks 1–2 bring mild improvement while swelling settles, month 1–2 is clearly better, and full effect arrives around month 3, when most men are able to stop their BPH medication.
Usually, with planning. Most blood thinners are paused 5–7 days beforehand, while low-dose aspirin is often continued — always coordinated with your cardiologist. We confirm a safe medication-holding plan during your consultation before you travel.
It's one all-inclusive direct-pay package: consultation, IPSS and uroflowmetry, prostate-volume and middle-lobe assessment, PSA screening, the Rezum system and single-use vapor needle, anesthesia, the 2–3 day catheter and its removal, and follow-up. No hidden facility or anesthesia add-ons, with itemized English receipts on request.
