BPH: Benign Prostatic Hyperplasia Explained
BPH, or benign prostatic hyperplasia, means non-cancerous enlargement of the prostate gland. It is common as men get older and can cause weak urine flow, frequent urination, urgency, night-time urination, straining and incomplete bladder emptying. BPH is not prostate cancer and does not turn into cancer, but the symptoms can sometimes overlap. Treatment depends on how much symptoms affect your life, urine flow, residual urine, prostate size, kidney function and complications. Options include observation, lifestyle changes, medicines, minimally invasive procedures or surgery.
BPH benign prostatic hyperplasia: short answer
BPH benign prostatic hyperplasia is age-related, non-cancerous growth of prostate tissue. The prostate sits below the bladder and surrounds the urine tube, called the urethra. When the prostate enlarges, it can narrow this urine passage or irritate the bladder.
This may cause:
- Weak urine stream
- Delay in starting urine
- Frequent urination
- Waking up at night to pass urine
- Sudden urgency
- Straining
- Dribbling after urination
- Feeling that the bladder is not empty
BPH is treatable. Many men improve with lifestyle changes and medicines. Some men need surgery if symptoms are severe, medicines do not help, or complications develop.
What is BPH?
The prostate is a small gland present only in men. It sits below the bladder. The urethra, which carries urine out of the body, passes through the prostate.
As men age, the prostate can slowly enlarge. This enlargement may press on the urethra and make the bladder work harder to push urine out.
You may hear a few related terms:
- BPH: benign prostatic hyperplasia, meaning non-cancerous growth of prostate tissue.
- BPE: benign prostate enlargement, meaning the prostate is enlarged.
- BPO: benign prostatic obstruction, meaning the enlarged prostate is blocking urine flow.
- LUTS: lower urinary tract symptoms, meaning urinary complaints such as weak flow, frequency, urgency and night urination.
Not every enlarged prostate causes symptoms. Some men have a large prostate but pass urine well. Others may have troublesome symptoms even with a moderately enlarged prostate. EAU Patient Information notes that prostate enlargement and prostate cancer are different conditions, although symptoms can sometimes be similar.
Does prostate size matter in BPH?
Yes, but prostate size alone does not decide treatment.
Many patients become anxious when an ultrasound report says “prostatomegaly” or “grade 1/2/3 prostate enlargement.” But a urologist does not treat the ultrasound number alone.
Treatment usually depends on:
- How troublesome your symptoms are
- Whether urine flow is weak
- How much urine remains after passing urine
- Whether the bladder wall is thickened
- Whether kidneys are swollen
- Whether urine infections, stones or retention have occurred
- PSA level, age and prostate examination findings
- Your general health and fitness for medicines or surgery
A large prostate with mild symptoms may need only observation or medicines. A smaller or moderately enlarged prostate with severe blockage may need more active treatment.
BPH vs prostate cancer
BPH is not prostate cancer. It does not become prostate cancer. But both conditions are more common in older men, and urinary symptoms can overlap. That is why PSA testing, prostate examination, MRI or biopsy may be advised in selected patients.
| Point | BPH | Prostate Cancer |
|---|---|---|
| Nature | Non-cancerous enlargement | Cancerous growth |
| Common age group | Usually older men | Usually older men |
| Symptoms | Weak flow, frequency, urgency, night urination | May be silent or may cause similar symptoms |
| Main concern | Urine blockage and bladder symptoms | Cancer risk, stage and spread |
| Tests | Urine tests, ultrasound, uroflowmetry, PSA when needed | PSA, prostate exam, MRI and biopsy when needed |
| Treatment | Lifestyle changes, medicines or surgery | Depends on cancer stage and risk group |
Symptoms of BPH
BPH symptoms are commonly grouped into storage, voiding and post-urination symptoms.
Storage symptoms
These happen when the bladder becomes overactive or irritated.
- Passing urine frequently
- Waking up at night to urinate
- Sudden urgency
- Urine leakage before reaching the toilet
- Feeling the need to pass urine again soon
Voiding symptoms
These happen when urine flow is blocked or weak.
- Slow urine stream
- Delay in starting urine
- Straining to pass urine
- Urine flow that starts and stops
- Taking a long time to finish
Post-urination symptoms
These occur after finishing urination.
- Dribbling after passing urine
- Feeling that urine is still left inside
- Need to pass urine again within a short time
NIDDK lists typical BPH symptoms such as frequent urination, urgency, weak stream, interrupted stream and difficulty starting urination.
What causes BPH?
BPH is mainly related to ageing and hormonal changes inside prostate tissue. It is not caused by sexual activity, masturbation, infection, “body heat” or weakness.
Risk factors may include:
- Increasing age
- Family history of prostate enlargement
- Obesity
- Diabetes
- Sedentary lifestyle
- Metabolic syndrome
- Heart and vascular risk factors
Other conditions can mimic BPH, including urinary tract infection, diabetes-related bladder problems, overactive bladder, urethral stricture, bladder stones, neurological disease and prostate cancer. This is why urinary symptoms should not be treated blindly with prostate tablets.
What happens if BPH is ignored?
Mild BPH may remain stable for years. But severe untreated obstruction can sometimes cause complications.
Possible complications include:
- Acute urinary retention
- Recurrent urinary tract infection
- Bladder stones
- Blood in urine
- Increasing post-void residual urine
- Bladder muscle weakness
- Kidney swelling
- Kidney function deterioration in severe cases
Most men with BPH do not need surgery. Persistent, worsening or complicated symptoms, however, deserve proper evaluation rather than repeated self-treatment.
When should you see a urologist?
See a urologist if urinary symptoms affect sleep, travel, work or daily comfort.
You should also consult if you have:
- Weak urine flow
- Frequent night urination
- Sudden urgency
- Straining to urinate
- Recurrent urine infection
- Blood in urine
- Incomplete emptying
- High residual urine on ultrasound
- Repeated catheterisation
- Symptoms not improving with medicines
NICE recommends specialist assessment for bothersome lower urinary tract symptoms that do not respond to conservative or medical treatment, and for complicated symptoms such as retention, recurrent infection, stones or suspected cancer.
Emergency signs: when to seek urgent care
Seek urgent medical care if you have:
- Complete inability to pass urine
- Severe lower abdominal pain with bladder fullness
- Fever, chills or weakness with urinary symptoms
- Blood clots in urine
- Heavy bleeding in urine
- Repeated vomiting or severe dehydration
- Confusion, drowsiness or signs of sepsis
- Known kidney swelling with worsening urine symptoms
Acute urinary retention may need catheter drainage and urgent evaluation.
How is BPH diagnosed?
Diagnosis starts with your symptoms, medical history and examination. Your urologist may ask about fluid intake, tea or coffee, alcohol, diabetes, constipation, sleep pattern, medicines and previous urinary problems.
Symptom score
Your doctor may use a questionnaire such as the IPSS, or International Prostate Symptom Score. It helps measure symptom severity and quality-of-life impact.
Urine routine and urine culture
These check for infection, blood, sugar, protein and pus cells.
Serum creatinine
This helps assess kidney function, especially if there is retention, recurrent infection, kidney swelling or long-standing obstruction.
PSA blood test
PSA is a prostate-related blood test. It may rise because of BPH, infection or prostatitis, acute urinary retention, recent prostate manipulation or procedures, and prostate cancer. A smooth urinary catheter alone usually has little effect on PSA.
Digital rectal examination
A doctor gently examines the prostate through the rectum to assess size, tenderness, hardness or nodules.
Ultrasound KUB with prostate and PVR
This checks the kidneys, bladder, prostate size and post-void residual urine.
Uroflowmetry
This test measures urine flow speed and pattern. It helps document whether the urine stream is weak.
Cystoscopy or urodynamic testing
These are not needed for every patient. They may be advised if diagnosis is unclear, surgery is being planned, or there is suspicion of urethral stricture, bladder stone or bladder dysfunction.
The AUA guideline focuses on evaluation and treatment of lower urinary tract symptoms attributed to BPH, including symptom assessment and selection of medical or procedural options based on patient findings and preferences.
How is BPH treatment decided?
BPH treatment is personalised. Your urologist may consider:
- Symptom severity
- Quality-of-life impact
- Prostate size and shape
- Urine flow rate
- Post-void residual urine
- Kidney function
- PSA and prostate examination findings
- Age and fitness for anaesthesia
- Sexual function priorities
- Blood thinner use
- Patient preference
NIDDK explains that BPH may be treated with watchful waiting, medicines or surgery depending on symptom severity and quality-of-life impact.
Lifestyle changes for mild BPH symptoms
For mild symptoms, lifestyle changes may help.
- Reducing fluids 2-3 hours before sleep
- Limiting evening tea, coffee and alcohol
- Passing urine before sleep and before travel
- Avoiding long urine holding
- Treating constipation
- Improving diabetes control
- Staying physically active
- Reviewing cold, allergy or sleep medicines with your doctor
Lifestyle changes may not shrink the prostate, but they can reduce symptom burden.
Medicines for BPH
Medicines are commonly used for mild-to-moderate bothersome symptoms.
Alpha-blockers
Alpha-blockers relax the prostate and bladder neck muscles so urine flows more easily. They often work quickly. Possible side effects include dizziness, low blood pressure, blocked nose and ejaculatory changes.
5-alpha reductase inhibitors
These medicines may slowly shrink the prostate and reduce progression risk in selected men with larger prostates. They take months to show benefit. Possible side effects include reduced libido, erectile difficulty and reduced semen volume.
Combination therapy
Some men benefit from an alpha-blocker plus a 5-alpha reductase inhibitor, especially when symptoms are bothersome and the prostate is larger.
Tadalafil
In selected men, especially those with erectile dysfunction and urinary symptoms, tadalafil may help. It is not suitable for men taking nitrate medicines for heart disease.
Bladder-calming medicines
If urgency, frequency or leakage is the main problem, bladder-calming medicines may be considered. These need careful use if residual urine is high.
Do not self-medicate. Prostate medicines can affect blood pressure, interact with other medicines or delay diagnosis of a different condition.
When is surgery needed for BPH?
Surgery may be advised if symptoms remain troublesome despite medicines or if complications develop.
Common reasons include:
- Repeated urinary retention
- Recurrent urinary infection due to obstruction
- Bladder stones
- Kidney swelling
- Kidney function changes
- Recurrent bleeding from prostate
- Very high post-void residual urine
- Severe quality-of-life impact
- Patient preference to avoid long-term medicines
Common BPH procedures and surgeries
The best procedure depends on prostate size, prostate shape, median lobe, bleeding risk, anaesthesia fitness, availability and surgeon expertise.
TURP
TURP, or transurethral resection of the prostate, removes obstructing prostate tissue through the urine passage. It is a standard option for many patients.
Bipolar TURP
Bipolar TURP is a modern TURP technique using saline irrigation. It is commonly used in many centres.
HoLEP or laser enucleation
HoLEP uses laser energy to remove obstructing prostate tissue. It is especially useful for larger prostates in experienced hands.
Laser vaporisation
Laser vaporisation may be suitable for selected patients, especially where bleeding risk needs special consideration.
Open or simple prostatectomy
This is now less common but may still be considered for very large prostates when appropriate.
Minimally invasive options
Options such as prostatic urethral lift, steam therapy, waterjet surgery and other technologies may be available in selected centres. Suitability depends on prostate anatomy, availability, cost and patient priorities, including sexual side-effect concerns.
No single procedure is best for everyone. Your urologist should explain expected symptom relief, catheter duration, hospital stay, bleeding risk, sexual side effects, chance of repeat treatment and follow-up.
Recovery and follow-up
Recovery depends on the treatment used. After medicines, follow-up is usually done to check symptom improvement, side effects, urine flow and residual urine when needed.
After procedures or surgery, follow-up commonly checks:
- Urine flow improvement
- Burning or bleeding
- Infection symptoms
- Catheter removal plan
- Residual urine
- Pathology report if tissue was removed
- Need for further medicines
EAU Patient Information notes that follow-up after minimally invasive therapies or surgery may include early review around 4-6 weeks, later review around 3 months and further follow-up depending on recovery.
Can BPH come back after treatment?
BPH is a long-term condition. Medicines may control symptoms for years, but symptoms can progress.
After surgery, many men get significant improvement. Some may later develop recurrent symptoms due to bladder weakness, urethral narrowing, residual prostate growth or overactive bladder. Follow-up helps identify the actual cause.
If you have weak urine flow, frequent urination at night, urgency, incomplete emptying or recurrent urine infection, a urology evaluation can help identify whether the cause is BPH, diabetes-related bladder changes, infection, urethral stricture, bladder stone or another condition.

FAQs
What is BPH benign prostatic hyperplasia?
BPH benign prostatic hyperplasia is non-cancerous prostate enlargement. It can narrow the urine passage and cause weak flow, frequent urination, urgency, night-time urination and incomplete emptying.
Is BPH dangerous?
Many cases are not dangerous. But severe untreated obstruction can sometimes cause urinary retention, infections, bladder stones, kidney swelling or kidney function problems.
Does BPH mean prostate cancer?
No. BPH is not prostate cancer and does not turn into cancer. But both can occur in older men, so PSA testing or prostate examination may be advised when appropriate.
Does prostate size decide whether I need surgery?
No. Prostate size is only one factor. Symptoms, urine flow, residual urine, complications, PSA, bladder condition and overall health also matter.
Can BPH be cured with medicines?
Medicines can control symptoms and may reduce prostate size in selected patients. They do not permanently remove enlarged tissue. Some men may eventually need a procedure or surgery.
When should BPH surgery be done?
Surgery is considered when symptoms remain troublesome despite medicines, or when complications occur, such as urinary retention, recurrent infections, bladder stones, kidney swelling, bleeding or very high residual urine.
Is frequent urination at night always due to BPH?
No. Night-time urination can also occur due to diabetes, excess evening fluids, sleep apnea, heart or kidney problems, certain medicines and overactive bladder.
Can I stop prostate medicines once symptoms improve?
Do not stop medicines without medical advice. Symptoms may return, and some medicines need planned follow-up.
