An enlarged prostate is not a disease you catch. It is a slow, near-universal change in men after about fifty, and it only becomes a problem when the enlargement starts to block the flow of urine. Most men need reassurance and simple medication. A minority need surgery, and the decision usually turns on complications rather than on the size of the gland.
What is BPH, in plain language?
The prostate is a small gland that sits below the bladder and surrounds the urinary passage. From middle age onwards it slowly grows. This growth is benign prostatic hyperplasia, or BPH: benign meaning non-cancerous, hyperplasia meaning an increase in the number of cells.
Because the passage runs straight through the gland, growth in the inner zone squeezes that passage. The bladder then has to push harder to empty. Over years, the bladder muscle thickens and becomes irritable, which is why the symptoms are a mix of two different things: difficulty pushing urine out, and a bladder that has become oversensitive.
What are the first symptoms of an enlarged prostate?
The earliest symptoms are usually a weaker urinary stream, having to wait before the flow starts, and getting up at night to pass urine. Many men also feel the bladder has not emptied completely. Symptoms build up over years, which is exactly why they get dismissed as normal ageing.
Obstructive symptoms, from the blockage
- A weak or thin stream, sometimes splitting or spraying
- Hesitancy: standing and waiting for the flow to begin
- Straining to pass urine
- An intermittent stream that stops and starts
- Dribbling at the end, and a feeling of incomplete emptying
Storage symptoms, from the irritable bladder
- Nocturia: waking once, twice or more at night to urinate. This is often the symptom that finally brings a man to the clinic, because it wrecks sleep
- Frequency during the day
- Urgency: a sudden need that is hard to postpone
- Occasionally, leakage before reaching the toilet
Go to a hospital the same day if you cannot pass urine at all and the lower abdomen is painful and distended. This is acute retention of urine. It needs a catheter urgently, and waiting at home does not resolve it.
Does an enlarged prostate mean cancer?
No. BPH is not cancer and does not turn into cancer. The two conditions are separate, and BPH is far more common.
The honest complication is that the symptoms can overlap. Early prostate cancer often produces no symptoms at all, and when it does, they can resemble BPH. This is why the standard evaluation includes a PSA blood test and a clinical examination, not because we expect cancer, but because it is not safe to assume it is absent. A man being treated for BPH should have this assessment done once properly rather than never.
What tests will the urologist advise?
The evaluation is simple, and most of it is done in a single visit.
| Test | What it tells us |
|---|---|
| Symptom score (IPSS) | A short questionnaire that turns vague complaints into a number, so severity and later improvement can be compared objectively |
| Urine routine and culture | Rules out infection, which can mimic or worsen the symptoms |
| Ultrasound KUB with post-void residue | Prostate size, bladder wall thickness, stones, and crucially how much urine is left behind after passing urine |
| Serum creatinine | Whether back pressure has started to affect kidney function |
| PSA | A screening blood test that helps separate BPH from prostate cancer; results are interpreted alongside age and prostate size |
| Uroflowmetry | Measures the actual flow rate, which is more objective than a description of the stream |
Can an enlarged prostate be treated without surgery?
Yes, in a large proportion of men. Treatment is matched to how much the symptoms are affecting daily life, not to the size of the gland on ultrasound. A very large prostate causing few symptoms may need nothing; a modestly enlarged one causing retention needs intervention.
1. Watchful waiting and simple measures
For mild symptoms, changes in habit often help enough:
- Shift most fluid intake to earlier in the day and reduce it in the two to three hours before sleeping
- Cut down alcohol and caffeine, both of which irritate the bladder
- Avoid holding urine for long periods
- Double voiding: passing urine, waiting half a minute, and trying again
- Review medicines with the doctor, since some cold and allergy preparations can worsen retention
2. Medication
- Alpha blockers relax the muscle in the prostate and bladder neck, easing the flow. They usually work within days to weeks. Light-headedness on standing and changes in ejaculation are the common side effects to know about.
- 5-alpha reductase inhibitors shrink the gland over months. They suit larger prostates and reduce the long-term risk of retention and the need for surgery. They also lower the PSA value, which must be accounted for when interpreting future tests.
- Combination therapy is used where the prostate is large and symptoms are moderate to severe.
- Anticholinergics or beta-3 agonists may be added when storage symptoms dominate, provided the bladder is emptying adequately.
When does an enlarged prostate need surgery?
Surgery is not decided by prostate size alone. It is advised when medicines are no longer controlling symptoms, or when any of the following complications appear:
- Retention of urine needing a catheter, especially if it recurs after a trial without catheter
- Repeated urinary tract infections
- Bladder stones forming because urine is never fully emptied
- Recurrent blood in the urine coming from the prostate
- Back pressure on the kidneys, with a rising creatinine
- A large residual volume after voiding, with a bladder that is beginning to decompensate
- Symptoms the man himself finds intolerable despite adequate medical treatment
The surgical options, and what they involve
All the standard procedures are done through the natural urinary passage. There is no external cut in the great majority of cases.
TURP (transurethral resection of the prostate)
The obstructing inner tissue is removed in small chips using a resectoscope passed through the passage. TURP has been performed for decades and remains the reference standard against which newer procedures are measured, because its results over the long term are the best documented. A catheter stays for a short period afterwards, and the removed tissue is sent for histopathology, which occasionally picks up an unsuspected cancer.
Bipolar TURP and TURIS
A refinement of the same operation using bipolar energy in saline. This removes the risk of the fluid-absorption problem that could occur with older monopolar systems, and it allows longer resections to be done more safely.
Laser procedures, including HoLEP
Lasers either vaporise the obstructing tissue or enucleate it, meaning the whole inner gland is peeled away from its capsule and then removed. Laser techniques are particularly useful for very large glands and for men who cannot safely stop blood-thinning medication. Bleeding is generally less, and the catheter time is often shorter.
Open or laparoscopic prostatectomy for BPH
Now uncommon, and reserved for exceptionally large glands or where a bladder stone or diverticulum has to be dealt with at the same time.
A note on what surgery does and does not do. Prostate surgery for BPH relieves the obstruction. It does not restore a bladder that has been damaged by years of straining, which is one reason not to postpone treatment indefinitely. Retrograde ejaculation, where semen passes backwards into the bladder, is a common and expected consequence of these procedures and should be discussed before, not after, the operation.
What recovery usually looks like
- A catheter for a short period, typically removed before discharge or shortly after
- Burning and urgency for a few days to a few weeks as the raw surface heals
- Some blood in the urine on and off for a few weeks, which is expected; heavy bleeding is not, and needs review
- Avoiding heavy lifting, straining and long journeys for a few weeks
- Drinking enough water, and treating constipation, both of which reduce bleeding
Timelines vary with the procedure, the size of the gland and the individual, so the figures your surgeon gives you for your own case are the ones that apply.
When to see a urologist
Book a consultation if you are getting up more than once a night to pass urine, if the stream has clearly weakened over the last year, if you have had an episode of retention, or if there is blood in the urine. Early assessment usually means the problem is still at the stage where tablets are enough.
