TURP in one honest paragraph
TURP (Transurethral Resection of the Prostate) has been refined over decades and is still one of the most reliable ways to relieve a blocked urinary channel. It works by removing obstructing tissue rather than shrinking it over time, so the improvement in flow tends to arrive sooner and last longer than with many minimally invasive options. The main trade-off is sexual: most men develop retrograde ejaculation (semen passes back into the bladder instead of out — harmless, but ejaculation feels "dry"). True erectile dysfunction is much less common. TURP is sometimes wrongly labelled the procedure with "the most side effects" — in reality its profile is well-characterised and predictable, and dry ejaculation is actually more common after some of the alternatives (more on that below). Whether TURP is right for you depends on your prostate size and anatomy, how much residual urine you carry, your medical and anaesthetic risk, and which outcomes matter most to you.
Quick navigation
What TURP is
A thin scope is passed along the urine passage — there is no external cut. The obstructing prostate tissue is removed from the inside, which widens the channel and improves flow. Because tissue is physically removed (rather than shrunk gradually, as with PAE or Rezūm), the change in stream is usually noticeable early, often within days of the catheter coming out.
Who is a good candidate
TURP is commonly considered when:
- Symptoms are moderate to severe and affecting quality of life
- Medicines aren't enough, aren't tolerated, or you'd prefer not to stay on them long-term
- There is high residual urine, recurrent retention, or catheter dependence
- Repeated urinary infections or bladder stones are occurring because of incomplete emptying
- There is blood in the urine attributable to the prostate, or rising kidney strain from back-pressure
- The obstruction needs more definitive relief within a predictable timeframe
Absolute reasons to treat surgically:
Some of these — recurrent infection, kidney impairment, recurrent stones or bleeding — are absolute reasons to treat surgically, regardless of how high the symptom score is.

When TURP is often preferred over minimally invasive options
A preference for "the least invasive option" is completely understandable — but it has to fit the clinical reality. The key difference is how each treatment opens the channel. TURP physically removes the obstructing tissue, so the passage is opened during the procedure itself and the result tends to hold. The minimally invasive options work differently and more slowly: Rezūm uses steam to kill tissue that the body then reabsorbs over weeks to months, and UroLift uses implants to hold the prostate lobes apart without removing anything. That gentler approach has real appeal, but it also means the response can be gradual, partial, and less durable — which is why re-treatment rates are higher. TURP is often the better choice when: • Rapid, definitive opening of the channel is needed, rather than a gradual response over months — TURP typically raises peak urine flow by about 10–12 mL/s and lowers the symptom (IPSS) score by around 15 points, usually within days, against a slower and smaller gain (roughly +4–6 mL/s) from the lighter options • Symptom burden is high and quality of life is significantly affected — for example, an IPSS symptom score in the severe range (20–35 out of a possible 35) • The prostate is large — generally above about 80 cc, where the minimally invasive options become less reliable; TURP suits glands up to roughly 80 cc, and the largest prostates are usually better treated by laser enucleation • Residual urine is high, or retention episodes keep recurring — a post-void residual over 50 mL is significant, and large residuals (often >100–200 mL) or repeated retention are situations where lighter treatments tend to under-perform • There are bladder stones, recurrent urinary infections (for instance three or more in a year), or recurrent bleeding that need addressing at the same time • There is concern about the bladder or kidneys from long-standing obstruction — for example a rising creatinine (reduced kidney function) or back-pressure on the kidneys (hydronephrosis) seen on the scan • You'd rather avoid a second procedure later — for context, TURP needs redoing in only about 1–2% of men in the first two years (roughly 1 in 50 to 1 in 100), rising to about 5–10% over a decade (around 1 in 10 to 1 in 20). That is lower than Rezūm (~7% by 3 years) and UroLift (~11% by 3 years), and far lower than PAE (~15–20% within 3–5 years, roughly 1 in 5 to 1 in 7 men) It's also worth knowing that Rezūm usually still requires a catheter for several days while the treated tissue swells and is reabsorbed, and that there is often an early phase where urinary symptoms feel worse before they improve. For a man who wants a single, dependable solution, that trade-off matters. TURP additionally provides tissue that is sent to the laboratory, which the tissue-preserving options cannot.
Pre-procedure evaluation (the tests that actually change the decision)
1. Urine test (and culture)
rules out infection and checks for blood in the urine. An active urinary infection is treated before surgery, since operating through infected urine raises the risk of complications.
2. Ultrasound (KUB) with post-void residual
one of the highest-value tests. It measures how much urine is left after voiding (significant if >50 mL), estimates prostate size, looks for bladder stones or wall thickening, and checks the kidneys for any back-pressure. Prostate size and shape (including whether there's an obstructing middle lobe) steer the choice between TURP and the minimally invasive options.
3. Symptom scoring and bladder diary
an IPSS questionnaire plus a frequency-volume chart capturing stream strength, straining, night-time waking (nocturia), urgency, leakage, retention episodes, and catheter or infection history. This gives an objective baseline to measure improvement against. Sexual function — including whether ejaculation matters to you — is discussed up front, because it shapes the trade-offs.
4. PSA and digital rectal exam, read in context
PSA helps interpret the prostate and may be raised simply by enlargement; the rectal exam assesses size and texture. Together they help decide whether anything needs ruling out before proceeding. PSA is not a standalone cancer test.
5. Flow rate and selected studies
uroflowmetry (a simple flow measurement), and in some cases a cystoscopy to look inside the urethra and bladder, or pressure-flow (urodynamic) studies when it's unclear whether the bladder or the prostate is the main problem.
6. Anaesthetic and bleeding work-up
bloods (including kidney function and a blood count), a review of heart and lung fitness for anaesthesia, and a plan for any blood thinners or antiplatelet medicines, which usually need pausing around surgery. For larger glands, your blood group is checked in case transfusion is ever needed.
Consent and Questions
You'll also have a chance to go through consent — what the procedure involves, the expected benefit, and the specific risks (especially retrograde ejaculation) — and to ask questions before the day.
What happens during TURP
There is no external cut and nothing is removed from the surface of your body — the entire operation is done through the natural urinary passage. • Anaesthesia. Given according to the plan — most often a spinal anaesthetic (you're numb from the waist down but awake), sometimes a general anaesthetic (asleep). Spinal anaesthesia is frequently preferred, and is well tolerated even by many men with heart conditions. • Access. A thin telescope called a resectoscope is passed along the urethra to the prostate. No incision is made on the body. • Resection. Using a fine electrically heated loop, the surgeon shaves away the obstructing prostate tissue from the inside in small pieces (often called "chips"), opening up the channel. The same energy seals small blood vessels to control bleeding as it goes. • Clearance and inspection. Sterile fluid continuously irrigates the area; the tissue chips are flushed out and collected. They are sent to the laboratory for examination — a useful by-product the tissue-preserving procedures can't offer. • Catheter. A catheter is placed at the end to drain urine and, if needed, to run a gentle bladder washout that keeps the urine clear while early bleeding settles. • Recovery on the day. You're monitored until the urine runs clear and voiding is stable once the catheter is out. Typical operating time is around 30 to 90 minutes depending on prostate size. A modern variation, bipolar TURP, uses saline irrigation and has made the procedure safer by largely removing the risk of the fluid-absorption problem (TUR syndrome) that was occasionally seen with the older technique.
Catheter and hospital stay
Expect a catheter for a short period (commonly a day to a few days) and a hospital stay of roughly 2–3 days so the team can watch for bleeding, run bladder irrigation if needed, manage comfort, and confirm safe voiding before discharge. Exact duration depends on how much tissue was removed, bleeding tendency, how quickly the urine clears, and your baseline bladder function.
Expected benefits and timeline
Early days
Because obstructing tissue is removed directly, flow often improves quickly. Some burning, urgency, frequency, and mild blood in the urine are normal while healing.
Over the following weeks
Most men notice a stronger stream, less straining, more complete emptying, less night-time waking, and better sleep. Storage symptoms (urgency, frequency) can take longer to settle if the bladder has been working against obstruction for years.
At three months
In trials, TURP delivers among the largest improvements of any BPH procedure — roughly a 15-point drop in IPSS and a 10–12 mL/s rise in peak flow at three months.
Risks and side effects
• Retrograde ejaculation — common (50–75%); ejaculation becomes "dry." Harmless, but usually permanent, and worth discussing if fertility or ejaculation matters to you. It's worth knowing this is more common after laser enucleation (HoLEP/ThuLEP, 60–80%) and open or robotic prostatectomy (80–95%), so it isn't unique to TURP. • Erectile dysfunction — uncommon (~3–10%). • Bleeding — usually controlled; occasionally needs irrigation. • Temporary irritation — burning, urgency, frequency during healing. • Urinary retention — in the early healing window (~4%). • Infection — managed with standard protocols. • Re-treatment — needed in a minority over long timeframes. • Anaesthetic risks — as with any procedure. Seek urgent help if: fever or chills, inability to pass urine, heavy bleeding with clots, or severe uncontrolled pain or weakness.
How TURP compares to HoLEP/ThuLEP, UroLift, Rezūm, and PAE
UroLift
Tiny implants hold the prostate open; no tissue cut, heated, or removed. Local anaesthesia, usually no catheter, day case, and a return to normal within days. Uniquely, it preserves ejaculation and erections. Trade-offs: the flow improvement is the most modest of this group, early burning and bleeding are common but short-lived, and roughly 1 in 7 to 1 in 8 men need a further procedure within five years. Best for small-to-moderate prostates where preserving sexual function is the priority.
Rezūm
The other ejaculation-sparing, minimally invasive option, using steam to destroy tissue that the body reabsorbs. Two honest differences from UroLift weigh against it for many men: relief is gradual, over weeks to months rather than within days, and a catheter is usually needed for several days while the treated prostate swells — often with an early phase where symptoms feel worse before they improve. In its favour, its re-treatment rate (~7% at 3 years) is a little lower than UroLift's. Best for selected smaller prostates where avoiding implants is preferred.
PAE (Prostate Artery Embolization)
A minimally invasive option performed by an interventional radiologist (not a urologist) through the wrist artery. It preserves ejaculation and avoids a catheter, but improvement is gradual, flow gains are smaller, the evidence is weaker, and it has the highest re-treatment rate of this group (~15–20% at 3–5 years, roughly 1 in 5 to 1 in 7 men).
TURP
The long-standing benchmark. It removes tissue, so it delivers a larger, more durable improvement in flow and a low long-term re-treatment rate — but it usually means a spinal or general anaesthetic, a catheter, a couple of days in hospital, and a high chance of "dry" (retrograde) ejaculation. Best when the obstruction needs the most definitive relief.
HoLEP / ThuLEP
Laser enucleation that also removes tissue, with the most durable results of the group (re-treatment under 2% at 5 years) and the ability to treat very large prostates. Like TURP, it commonly causes retrograde ejaculation and needs anaesthesia and a catheter.
