Benign Prostatic Hyperplasia (BPH): Recognising Symptoms and When to Seek Help

Benign Prostatic Hyperplasia (BPH) is a common condition that many men experience as they age. This non-cancerous enlargement of the prostate gland occurs as part of the natural ageing process, though its impact on daily life varies significantly between individuals. The prostate surrounds the urethra—the tube that carries urine out of the body- and as the gland enlarges, it can compress this pathway and impede the flow of urine. This often leads to various urinary symptoms that may interfere with sleep, work, and overall quality of life.

What Is Benign Prostatic Hyperplasia?

Benign prostatic hyperplasia refers to the non-cancerous growth of prostate tissue that commonly occurs with age. Unlike prostate cancer, BPH does not spread to other parts of the body and is not life-threatening. However, the physical changes it causes can lead to significant urinary dysfunction.

The exact cause of BPH remains unclear, though hormonal changes associated with ageing—particularly involving testosterone and dihydrotestosterone (DHT)—are believed to play a central role. As men age, the balance of these hormones shifts, potentially triggering prostate cell growth.

Recognising the Symptoms of BPH

Lower Urinary Tract Symptoms (LUTS)

BPH primarily manifests through a cluster of urinary symptoms collectively known as lower urinary tract symptoms:

Obstructive Symptoms:

• Difficulty initiating urination (hesitancy)
• Weak or interrupted urine stream
• Straining to empty the bladder
• Prolonged urination
• Sensation of incomplete bladder emptying
• Dribbling at the end of urination

Irritative Symptoms:

• Increased urinary frequency (more than eight times per day)
• Urgent need to urinate
• Nocturia (waking multiple times at night to urinate)
• Occasional urge incontinence

Severity and Impact

The severity of BPH symptoms does not always correlate with prostate size. Some men with significant enlargement experience minimal symptoms, while others with modest enlargement face considerable difficulty. The International Prostate Symptom Score (IPSS) questionnaire is commonly used to assess symptom severity and guide treatment decisions.

Potential Complications

If left untreated, severe BPH can lead to:

• Acute urinary retention (sudden inability to urinate)
• Recurrent urinary tract infections
• Bladder stones
• Bladder damage
• Kidney damage due to chronic retention

Diagnostic Approaches

Medical History and Physical Examination

Diagnosis begins with a detailed discussion of symptoms, medical history, and their impact on quality of life. A digital rectal examination (DRE) allows the doctor to assess the size, shape, and consistency of the prostate.

Laboratory Tests

• Urinalysis: Screens for infection, blood, or other abnormalities
• Prostate-Specific Antigen (PSA) Test: Elevated PSA levels may indicate BPH, prostate cancer, or prostatitis, requiring further evaluation

Specialised Tests

When symptoms are severe or the diagnosis is unclear, additional investigations may include:

• Uroflowmetry: Measures urine flow rate and volume
• Post-Void Residual (PVR) Measurement: Assesses how much urine remains in the bladder after urination
• Bladder Diary: Tracks fluid intake, urination frequency, and volume over several days
• Cystoscopy: Direct visualisation of the urethra and bladder using a thin, flexible tube
• Transrectal Ultrasound: Provides detailed imaging of the prostate
• Urodynamic Studies: Evaluates bladder pressure and function during filling and emptying

Treatment Options

Watchful Waiting

For men with mild symptoms that do not significantly impact quality of life, active monitoring without immediate treatment may be appropriate. This involves regular check-ups and reassessment of symptoms.

Lifestyle Modifications

• Limiting fluid intake before bedtime or outings
• Reducing caffeine and alcohol consumption
• Double voiding (urinating, then waiting a moment and trying again)
• Scheduled bathroom trips
• Managing constipation, which can worsen urinary symptoms

Medications

Alpha-Blockers (e.g., tamsulosin, alfuzosin): Relax prostate and bladder neck muscles to improve urine flow. Effects are typically noticed within days to weeks.

5-Alpha Reductase Inhibitors (e.g., finasteride, dutasteride): Shrink the prostate by blocking hormone conversion. Results may take several months, but can significantly reduce prostate size.

Combination Therapy: Using both medication types may be more effective for moderate-to-severe symptoms.

Phosphodiesterase-5 Inhibitors (e.g., tadalafil): May improve both urinary symptoms and erectile function in some men.

Minimally Invasive Procedures

When medications are ineffective or unsuitable, less invasive techniques include:

• Transurethral microwave thermotherapy (TUMT)
• Transurethral needle ablation (TUNA)
• Prostatic urethral lift (UroLift)
• Water vapour therapy (Rezūm)

Surgical Interventions

Transurethral Resection of the Prostate (TURP): The gold standard surgical treatment, involving removal of excess prostate tissue through the urethra.

Holmium Laser Enucleation of the Prostate (HoLEP): Uses laser energy to remove obstructing tissue, often suitable for larger prostates.

Open or Robot-Assisted Prostatectomy: Reserved for very large prostates or when other approaches are not feasible.

When to Seek Medical Attention

Immediate medical care is necessary if you experience:

• Sudden inability to urinate
• Severe pain or discomfort in the lower abdomen
• Blood in the urine
• Signs of urinary tract infection (fever, burning, cloudy or foul-smelling urine)

Schedule a consultation if:

• Urinary symptoms interfere with daily activities or sleep
• You notice progressive worsening of symptoms
• Symptoms cause significant concern or distress

Commonly Asked Questions

Is benign prostatic hyperplasia (BPH) the same as prostate cancer?

No. BPH is a non-cancerous enlargement of the prostate and does not spread to other parts of the body. While both conditions can share similar urinary symptoms, they are different conditions with different causes and management approaches. Further evaluation, including PSA testing and clinical assessment, helps differentiate between them.

Does prostate size determine how severe my symptoms will be?

Not necessarily. Symptom severity does not always correlate with prostate size. Some men with a relatively enlarged prostate may experience mild symptoms, while others with smaller enlargement may have significant urinary difficulties. Factors such as bladder function and degree of urethral compression also play a role.

Can BPH improve on its own without treatment?

In some men with mild symptoms, BPH may remain stable for long periods with watchful waiting and lifestyle adjustments. However, symptoms can progress over time in others. Regular follow-up is essential to monitor changes and identify potential complications early.

Are medications for BPH effective for everyone?

Medications such as alpha-blockers and 5-alpha reductase inhibitors may help improve urinary symptoms in many patients, particularly in suitable candidates. Response varies between individuals, and some men may experience side effects or insufficient symptom relief, requiring alternative treatment options.

How long does it take for BPH medications to work?

Alpha-blockers typically begin improving symptoms within days to a few weeks. In contrast, 5-alpha reductase inhibitors usually require several months to show noticeable effects, as they gradually reduce prostate size. Individual response times may vary.

Conclusion

BPH is a manageable condition with multiple treatment approaches tailored to symptom severity and individual circumstances. Early evaluation allows for timely intervention before complications develop. Effective treatments—ranging from lifestyle adjustments to advanced surgical options—can restore urinary function and significantly improve quality of life.

If you are experiencing a weak urinary stream, frequent nighttime urination, or difficulty emptying your bladder, consult with Dr Azhari. An early urologist evaluation ensures accurate diagnosis and access to the most appropriate treatment options for your specific situation.
