Rezum water-vapor BPH therapy in Busan Seomyeon — for prostates a lift can't fix.
At Urogyn in Busan Seomyeon, one minute from Seomyeon Station Exit 7, 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.
What Busan patients ask before choosing Rezum.
- I was told my prostate is too large for a lift, or that a middle lobe is the real problem. What now?
- I want the gland actually reduced, not just held open — is there a procedure that does that without surgery?
- How long is the catheter, honestly? That is the part I am least willing to accept.
- How long before I notice a difference? I have read that steam takes weeks rather than days.
- Will I still ejaculate normally? I know the answer for lifts — what is it for Rezum?
All five come up most weeks at our Busan Seomyeon clinic. The sections below answer them in order — what the vapor actually does, who the ₩600,000 work-up says yes and no to, the two real trade-offs, and what the first three months look like.
What is Rezum, and who is it for?
Rezum is a water-vapor treatment for benign prostatic hyperplasia in which a urologist delivers brief 9-second bursts of steam into the enlarged prostate through a cystoscope. The vapor ablates excess tissue, which the body then reabsorbs, so the gland genuinely reduces in volume rather than being held open. At Urogyn Men's Clinic in Busan Seomyeon it takes 15–30 minutes under local anaesthesia with sedation, from ₩10,000,000, after a ₩600,000 prostate work-up.
It is the option our Busan urologists reach for when a lift cannot cover the anatomy: glands over about 80 g, and prostates with a prominent median lobe pushing into the bladder. Two honest trade-offs come with that power — a catheter for several days, and a build to full effect over weeks to three months rather than immediately. If your prostate is smaller and lobe-free, UroLift in Busan or Progator gives faster relief without the catheter; the UroLift vs Rezum guide sets the decision out in full.
“When a prostate in Busan or anywhere 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 at our Busan clinic.
UroLift and Progator hold the prostate open. Rezum shrinks it — which is why our Busan urologists reach for it in the cases a lift can't cover.
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 in Busan.
Honest numbers from our Busan Seomyeon clinic — including the parts that take patience.
How the vapor treatment works in Busan Seomyeon.
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.

A short animation of how each vapor burst ablates excess prostate tissue — no cutting, no implant — the same system our Busan urologists use.
Compared honestly with the other Busan BPH options.
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 three BPH procedures are ₩10,000,000 at our Busan clinic, so the choice is about your anatomy, not price.

What you accept in return — our Busan urologists say it first.
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
When Rezum earns its place in Busan — and when a lift is the better answer.
All three BPH procedures are the same published price here, so this is decided on anatomy and on what you are willing to accept.
Rezum earns it if you…
- Have a prostate over about 80 g, where implant- and suture-based lifts reach their limit
- Have a prominent median lobe pushing into the bladder — the anatomy a lift cannot address
- Want the gland genuinely reduced rather than mechanically held open
- Can accept a catheter for several days and a build to full effect over weeks
- Want ejaculation and erections preserved — a small share notice some retrograde ejaculation, which the urologist quantifies at the work-up
- Have time in Busan for the catheter to come out before flying home
We'll suggest a lift instead if you…
- Have a prostate under about 80 g with no significant median lobe — UroLift in Busan gives faster relief, usually with no catheter
- Cannot spare the days a catheter needs before your flight home
- Need immediate improvement rather than a gradual one over weeks
- Have never tried medication with mild symptoms — a tablet is cheaper, and we say so
- Have pain, burning or urgency rather than a weak stream — that is prostatitis, not obstruction
- Have a PSA out of proportion to prostate size — assessed before any BPH treatment
Is Rezum in Busan right for you ?
Around 35% of the procedural BPH patients at our Busan clinic 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 at our Busan clinic — the same Rezum system used at leading international centres.
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 in Busan 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.

What our Busan urologists are asked once the basics are clear.
Why does steam take weeks when a lift works immediately?
Because the mechanisms differ. A lift opens the channel mechanically, so flow improves the same day. Rezum ablates tissue that the body then reabsorbs over weeks — the gland shrinks progressively, and symptom scores keep improving to about three months. That is the price of treating an anatomy a lift cannot reach, and our Busan urologists state it before you book rather than after.
How long is the catheter really, and can I fly with it?
Several days in most cases, and no — the flight home is planned after removal. That is the single most common reason a man with a suitable prostate still chooses a lift instead, and it is a legitimate reason. Tell the clinic your travel dates in the first message and the plan is built around them.
What is the retrograde ejaculation risk, honestly?
A small share of men — roughly 5–10% in published series — notice some retrograde ejaculation after Rezum. For context, lifts preserve function in nearly all men, while common BPH medication causes it far more often. The urologist gives you the figure for your case at the work-up; if preserving ejaculation is your single highest priority and your prostate suits a lift, he will say so.
Can I have Rezum if I am on blood thinners?
Often, with planning. Anticoagulants are usually paused briefly around the procedure in agreement with your prescribing doctor. Tell the clinic in your first message so this is arranged before you travel to Busan, not on the day.
What if it is not enough — what comes next?
Rezum can be repeated, and it does not prevent a later lift or a hospital operation. BPH is progressive, so a minority of men need further treatment years later whichever route they take; the prostate care hub sets out how the three procedures relate to each other over time.
Before you fly to Busan.
Rezum injects brief 9-second bursts of water vapor into the enlarged prostate through a cystoscope. The steam ablates excess tissue, which the body reabsorbs over the following weeks, so the gland genuinely reduces in volume rather than being held open mechanically. It is performed at our Busan Seomyeon clinic under local anaesthesia with sedation.
₩10,000,000, all-inclusive — the procedure, the anaesthesia and the clinic's procedure-room use, with no facility or anaesthesia add-ons. The ₩600,000 prostate work-up is listed separately. UroLift and Progator start from the same figure at our Busan Seomyeon clinic, so the choice between them is clinical rather than commercial.
Because it reduces tissue volume rather than holding the channel open. Implant- and suture-based lifts used at our Busan clinic reach their limit at around 80 g and cannot address a prominent median lobe pushing into the bladder; Rezum treats both. For smaller lobe-free glands a lift is usually the better choice.
Erections are preserved. A small share of men treated in Busan — roughly 5–10% in published series — notice some retrograde ejaculation; lifts preserve function in nearly all men, while common BPH medication causes it far more often. Your Busan urologist gives you the figure for your case at the work-up.
Several days in most cases, and the flight home from Busan is planned after removal rather than with it in place. This is the most common reason a man with a suitable prostate chooses a lift instead, and it is a legitimate one.
Progressively. Flow usually improves over the first weeks after the Busan procedure as the treated tissue is reabsorbed, with symptom scores continuing to improve to about three months. Rezum is not the choice if you need immediate relief — a lift is.
Testosterone, PSA, urine analysis and prostate ultrasound together, in one same-day visit in Busan. Prostate volume and median lobe from that ultrasound are what decide between Rezum and a lift. If you bring a recent scan with volume, the urologist says which components can be skipped.
Often, with planning. Anticoagulants are usually paused briefly around the Busan procedure in agreement with your prescribing doctor, and diabetes should be reasonably controlled. Tell the clinic in your first message so this is arranged before you travel.
No. Rezum is performed under local anaesthesia with sedation in the clinic's own procedure room in Seomyeon, takes 15–30 minutes, and most men are discharged the same day.
Longer than for a lift, because the catheter comes out before you fly — typically four to seven nights in total including the work-up visit. Your urologist confirms the figure in writing after the procedure, from how it went.
In the first weeks: burning on urination, blood in the urine, urgency and pelvic discomfort while treated tissue is reabsorbed — expected and self-limiting. Uncommon: urinary infection, retention requiring a longer catheter, or insufficient relief needing repeat treatment. Fever, inability to pass urine or heavy bleeding with clots are reasons to message the Busan clinic the same day.
It can be repeated at our Busan clinic, and it does not prevent a later lift or a hospital operation. BPH is progressive, so a minority of men need further treatment years later whichever route they take.
The procedure, the anaesthesia and the procedure-room use at our Busan clinic, as one all-inclusive direct-pay package. Not included: the ₩600,000 prostate work-up, listed separately because some men arrive with recent results from home.
No. Urogyn publishes one self-pay price list in Korean won and applies it to every patient. Nationality, language and booking from abroad change no figure.
Yes. The board-certified urologist in Busan who consults with you is the same doctor who performs your procedure and manages your follow-up — one specialist from start to finish. You are never passed to a junior doctor or a different surgeon.
Three things. Immediate relief — the effect builds over weeks to three months, and a lift is the answer if you need it faster. A catheter-free recovery — several days is usual, and it must come out before you fly. And a permanent result — BPH keeps progressing and some men need more treatment years later. Our Busan urologists say all three before you book.
