Benign Prostatic Hyperplasia (BPH)

Benign Prostatic Hyperplasia (BPH) is a non-cancerous enlargement of the prostate gland that commonly affects men as they age. This condition involves the growth of additional prostate tissue around the urethra, which can restrict urine flow from the bladder. The prostate continues to grow throughout a man’s life, and when this growth becomes excessive, it may cause urinary symptoms that can affect daily activities and quality of life.

Symptoms of Benign Prostatic Hyperplasia

Men with BPH may experience various urinary symptoms that tend to develop gradually over time and can range from mild to severe.

  • Frequent Urination

    The need to urinate more often than usual, particularly at night (nocturia). This occurs because the bladder cannot empty completely, leading to more frequent urges to urinate.

  • Weak Urine Stream

    Reduced force in the urine stream that may start and stop intermittently. The enlarged prostate narrows the urethra, making it harder for urine to pass through with normal pressure.

  • Difficulty Starting Urination

    A delay in beginning urination despite feeling the need to go. This hesitancy happens because the enlarged prostate blocks the bladder outlet, requiring more bladder pressure to initiate flow.

  • Incomplete Emptying

    A sensation that the bladder has not completely emptied after urination. Residual urine remains in the bladder because the obstruction prevents complete emptying.

  • Urinary Urgency

    Sudden, compelling need to urinate that is difficult to defer. This urgency develops as the bladder becomes more sensitive due to working against the prostatic obstruction.

  • Urinary Incontinence

    Involuntary leakage of urine, which can occur when urgency cannot be controlled. The bladder may contract unexpectedly due to increased sensitivity and pressure.

  • Straining During Urination

    Needing to push or strain to maintain urine flow. This straining compensates for the increased resistance caused by the enlarged prostate.

  • Blood in Urine

    Occasional presence of blood in the urine, which may indicate irritation or small blood vessel ruptures. This symptom can occur as urine forces its way through the narrowed passage.

Causes and Risk Factors

Several factors appear to influence the development and progression of BPH in men. These include:

Age

The likelihood of developing BPH increases significantly after age 50. By age 60, about half of men have some degree of BPH, and by age 85, the percentage rises even higher.

Hormonal Changes

Changes in the balance of sex hormones, particularly dihydrotestosterone (DHT), as men age. DHT, a derivative of testosterone, continues to promote prostate cell growth even as men get older.

Family History

Men with close relatives who have BPH have a higher chance of developing the condition. Genetic factors may influence how the prostate responds to hormones throughout life.

Lifestyle Factors

A diet high in fat, red meat, and dairy products may increase risk. Conversely, regular physical activity and consuming vegetables may help reduce the risk of BPH.

Medical Conditions

Heart disease and obesity have been associated with increased risk of BPH. These conditions may affect hormone levels or blood flow to the prostate gland.

Medications

Certain medications, particularly some antihistamines and decongestants, can worsen BPH symptoms. These medications can affect bladder function or cause further constriction of urinary passages.

Diagnostic Methods

  • Medical History and Symptom Assessment

    The doctor reviews the patient’s complete medical history and evaluates urinary symptoms using standardised questionnaires. These questionnaires help quantify symptom severity and impact on quality of life.

  • Physical Examination

    A digital rectal examination (DRE) allows the doctor to feel the size and consistency of the prostate gland. During this examination, the doctor inserts a gloved, lubricated finger into the rectum to assess the posterior surface of the prostate.

  • Urinalysis

    Testing of a urine sample to check for blood, infection, or other abnormalities that might explain the symptoms. This test helps rule out conditions such as urinary tract infections or bladder stones.

  • Blood Tests

    Measurements of kidney function and prostate-specific antigen (PSA) levels may be conducted. PSA is a protein produced by the prostate, and elevated levels may indicate prostate enlargement, inflammation, or cancer.

  • Uroflowmetry

    A test that measures the speed and volume of urine flow during urination. The patient urinates into a device that records how quickly the urine is flowing and the total volume expelled.

  • Cystoscopy

    A procedure where a thin, flexible scope with a light and camera is inserted through the urethra to examine the bladder and prostate. This allows direct visualisation of any obstruction or abnormality within the urinary tract.

Treatment Options

Treatment for BPH depends on symptom severity, prostate size, age, overall health, and how the symptoms affect quality of life.

Monitoring

Monitoring the condition without active treatment for men with mild symptoms. This approach involves regular check-ups to track any progression of symptoms and may include lifestyle modifications such as reducing evening fluid intake, limiting alcohol and caffeine, and scheduled voiding.

Alpha Blockers

These medications relax the smooth muscles in the prostate and bladder neck to improve urine flow. Alpha blockers work quickly, usually within days, and include medications such as tamsulosin, alfuzosin, and silodosin that target the prostate area with fewer side effects than older medications.

5-Alpha Reductase Inhibitors

These drugs shrink the prostate by blocking the hormone that promotes prostate growth. These medications, including finasteride and dutasteride, may take up to six months to become effective and are particularly helpful for men with significantly enlarged prostates.

Combination Therapy

Using both alpha blockers and 5-alpha reductase inhibitors together for enhanced effectiveness. This approach combines the immediate symptom relief of alpha blockers with the long-term prostate-shrinking effects of 5-alpha reductase inhibitors, making it particularly effective for men with larger prostates and moderate to severe symptoms.

Phosphodiesterase-5 Inhibitors

These medications are typically used for erectile dysfunction and can also help relieve BPH symptoms. These drugs, such as tadalafil, work by relaxing smooth muscles in the bladder and prostate while also improving blood flow to the genital area.

Prevention and Management

While BPH cannot be completely prevented, certain lifestyle measures may help manage symptoms and potentially slow progression. Maintaining a healthy weight through regular physical activity and a balanced diet rich in fruits, vegetables, and whole grains may benefit prostate health. Limiting caffeine and alcohol consumption can reduce urinary frequency and urgency. Avoiding antihistamines and decongestants, which can worsen urinary retention, may help manage symptoms. Men should practise timed voiding, emptying the bladder regularly even when not feeling the urge, and avoid long periods without urination. Regular medical check-ups allow for early detection and management before symptoms become severe.

    Frequently Asked Questions

    Can BPH lead to prostate cancer?

    BPH and prostate cancer are two separate conditions that can occur independently or simultaneously. Having BPH does not increase the risk of developing prostate cancer. However, because the symptoms can sometimes be similar, it is necessary to rule out prostate cancer during BPH diagnosis.

    How quickly do BPH symptoms progress?

    The progression of BPH varies greatly among individuals. Some men experience slow symptom development over many years, while others may have more rapid changes. About one-third of men with mild BPH find that their symptoms stabilise or even improve without treatment.

    What complications can occur if BPH is left untreated?

    Untreated BPH can lead to complications including acute urinary retention (sudden inability to urinate), urinary tract infections, bladder stones, bladder damage due to stretching, and kidney damage from back pressure of retained urine. These complications may require emergency treatment.
