Prostate enlargement (BPH), LUTS, medications and modern minimally-invasive surgery.
Benign prostatic hyperplasia — non-cancerous enlargement that presses on the urethra. Modern medication, UroLift, Rezum and TURP give options across the severity spectrum.

Key facts
Prostate enlargement at a glance.
The essentials, in plain English — what it is, how common it is, how severity is scored, and how it is treated in the UK today.
-
What it is
Benign, non-cancerous enlargement of the prostate that presses on the urethra and disturbs urine flow.
-
How common
Very common with age — affecting roughly half of men in their 50s and up to 90% by their 80s.
-
How severity is measured
The International Prostate Symptom Score (IPSS) turns your symptoms into a mild / moderate / severe grade.
-
First-line treatment
Modern medication — alpha-blockers and 5-alpha-reductase inhibitors — works well for most men.
-
Minimally-invasive options
UroLift, Rezum and iTind preserve sexual function and avoid a general anaesthetic in many cases.
-
Gold-standard surgery
TURP (transurethral resection of the prostate) remains the reference operation for larger glands.
Why this guide matters
The right choice depends on the right assessment.
BPH is common and treatable — but the options have widened enormously in the last decade. The three points below shape everything else on this page.
-
It is not cancer — but check anyway
BPH is benign. A PSA, examination and sometimes an MRI make sure nothing else is missed.
-
The IPSS turns feelings into numbers
A validated score lets you and your clinician track whether treatment is actually helping.
-
Surgery has changed
UroLift, Rezum and iTind mean many men now avoid a general anaesthetic and preserve sexual function.
How the diagnosis is made
From first symptoms to a clear plan.
The steps a UK GP and urologist will normally follow, in order — so you know what to expect and why.
Phase 1 · Assessing
Scoring symptoms and excluding other causes
Phase 2 · Measuring
Flow, residual volume and prostate size
Phase 3 · Planning
Specialist review and treatment choice
- 01
Assessing
Symptom review (IPSS score)
A short questionnaire that turns your symptoms into a number, so change can be tracked.
- 02
Assessing
Urinalysis and PSA
A dipstick to exclude infection or blood, and a blood test to help rule out prostate cancer.
- 03
Assessing
Bladder diary
Three days of fluid in, urine out, and how often you go — surprisingly useful.
- 04
Measuring
Post-void residual ultrasound
A quick scan of the bladder after you pass urine, to see how much is left behind.
- 05
Measuring
Uroflowmetry
You pass urine into a specialised toilet that measures the strength and shape of your flow.
- 06
Measuring
Digital rectal examination
A brief exam that gives the clinician the size and feel of the prostate.
- 07
Planning
Urology consultation
A specialist ties the findings together and talks through medication or procedure options.
Typical timeline: 4–8 weeks from first appointment to a settled plan.
Symptoms
The LUTS pattern most men recognise.
Lower urinary tract symptoms come in two flavours — storage and voiding. Here is what to look for and when to seek urgent care.
-
Frequency
Passing urine more often than usual through the day.
-
Hesitancy
A delay between trying to pass urine and the stream actually starting.
-
Weak stream
A slower, thinner flow that can start and stop.
-
Urgency
A sudden, hard-to-defer need to pass urine.
-
Nocturia
Waking one or more times at night to pass urine.
-
Incomplete emptying / double voiding
A feeling that the bladder is not empty — some men go again a minute or two later.
-
Post-void dribbling
A little leak of urine after finishing — often into underwear.
-
Red flag — acute retention
A sudden inability to pass urine with a painful, distended bladder — call 999 or attend urgent urology.
Treatment
How BPH is treated in the UK today.
Lifestyle and medication first, procedures where symptoms or complications demand it — what each option does, and how it typically feels.
-
Watchful waiting + lifestyle
Fluid timing, caffeine and alcohol changes, bladder training — enough for many with mild symptoms.
-
Alpha-blocker
Tamsulosin or alfuzosin relaxes the prostate muscle; symptoms usually ease within days.
-
5-alpha-reductase inhibitor
Finasteride or dutasteride shrinks the prostate over months — best for larger glands.
-
Combination therapy
An alpha-blocker plus a 5-ARI for men with a bigger prostate and moderate-to-severe symptoms.
-
UroLift
Small implants hold the prostate lobes apart. Day case, no cutting or heating, sexual function preserved.
-
Rezum (water-vapour therapy)
Steam is injected into the prostate to shrink tissue. Day case, minimal impact on erection and ejaculation.
-
iTind
A temporary nitinol device reshapes the prostate over five days, then is removed — no permanent implant.
-
TURP
Transurethral resection of the prostate — the reference operation for larger glands, in theatre under anaesthetic.

Red flags
When BPH stops being routine.
Most of the time, BPH progresses slowly. These are the situations where it does not — and you should act today.
-
Acute urinary retention
Sudden inability to pass urine, painful distended bladder — 999 or urgent urology assessment.
-
Recurrent urinary tract infections
Repeated UTIs in a man usually need investigation — obstruction may be behind it.
-
Blood in the urine (haematuria)
Visible or persistent microscopic blood needs prompt urology review to exclude other causes.
-
Bladder stones
Long-standing incomplete emptying can form stones — they need treatment in their own right.
-
Renal impairment from obstruction
Back-pressure on the kidneys shows up on blood tests and needs urgent decompression.
-
Rapidly rising PSA
A quick climb warrants prostate MRI and urology review to exclude cancer.
-
Nocturnal enuresis (chronic retention)
Wetting the bed as an adult can signal a chronically overfull bladder — seek review.
-
Post-operative bleeding or infection
Fever, heavy bleeding, or difficulty passing urine after any prostate procedure — contact your team same-day.
-
Erectile dysfunction after treatment
Discuss openly at follow-up — many causes are modifiable and treatable.
Living with it
A long-term condition, but a very manageable one.
Four things that make the biggest difference day to day — habits, monitoring, medication and reviews.
A quiet reminder
Track the trend, not the day.
Symptoms vary week to week. The IPSS every few months is the honest measure of whether things are getting better.
- 01 Daily habits
Fluid timing beats fluid volume
Stop drinking two hours before bed, and skip late-evening caffeine and alcohol — nocturia usually settles.
- 02 Monitoring
Repeat the IPSS every few months
A number you can track shows whether medication is really working — or if it is time to escalate.
- 03 Medication
Give tablets time — and read the label
Alpha-blockers work in days; 5-ARIs take months. Both have sexual side effects worth knowing about up front.
- 04 Reviews
Annual review as a minimum
Symptoms, PSA, kidney function and medication tolerance — a yearly check keeps you ahead of trouble.
Frequently asked
Everything we get asked about prostate enlargement.
Quick answers on scoring, medication, minimally-invasive procedures and when to worry.
-
Is an enlarged prostate the same as prostate cancer?
No. BPH is a benign, non-cancerous enlargement. The two conditions can coexist, which is why PSA and — in some cases — an MRI are checked at diagnosis.
-
How is severity measured?
The International Prostate Symptom Score (IPSS) — seven questions turning your symptoms into a number, graded mild (0–7), moderate (8–19) or severe (20–35).
-
Do I have to take medication forever?
Alpha-blockers work only while you take them. 5-ARIs need long-term use to keep the prostate shrunk. If a procedure like UroLift or TURP is done, medication can often stop.
-
Which treatment preserves sexual function best?
UroLift has the strongest evidence for preserving both erection and ejaculation. Rezum and iTind also perform well. 5-ARIs and TURP more commonly affect ejaculation.
-
Is TURP still the gold standard?
For larger prostates, yes — TURP has decades of outcome data. For smaller-to-moderate glands, minimally-invasive options are increasingly the first choice.
-
When should I call 999?
A sudden inability to pass urine with a painful, swollen lower abdomen is acute retention — an emergency needing a catheter today.
