Prostate Issues in Aging Men: Screening, Symptoms, and Treatment Options

Prostate problems are nearly universal in elderly men. The prostate, a walnut-sized gland surrounding the urethra, enlarges with age in most men (benign prostatic hyperplasia or BPH), causing urinary symptoms. Additionally, prostate cancer is common but often slow-growing and may not cause death. Families caring for elderly fathers or grandfathers often navigate questions about screening, symptom management, and when treatment is necessary. Understanding these issues helps families make informed decisions.

The Prostate: Basic Anatomy and Function

The prostate is a gland that produces fluid that forms part of semen. It is located below the bladder and surrounds the urethra (the tube through which urine and semen exit the body).

In young men, the prostate is about the size of a walnut. With age, the prostate typically enlarges, potentially causing urinary symptoms.

Benign Prostatic Hyperplasia (BPH)

BPH is non-cancerous enlargement of the prostate, extremely common in elderly men:

Age and prevalence:

• Age 50-59: 30% have BPH
• Age 60-69: 50% have BPH
• Age 70+: 70% have BPH

Symptoms of BPH:

• Urinary frequency: needing to urinate 8+ times daily, especially bothersome
• Nocturia: waking multiple times at night to urinate (severely impacts sleep quality)
• Urgency: sudden need to urinate, difficulty deferring
• Weak or hesitant urinary stream: difficulty starting urination, slow flow
• Straining: need to push to urinate
• Feeling of incomplete emptying: feeling bladder is not completely empty after urination
• Dribbling: urine drips after urination

Severity scales: The International Prostate Symptom Score (IPSS) quantifies symptom severity (0-7 mild, 8-19 moderate, 20-35 severe).

When BPH requires treatment:

• Symptoms are moderate to severe (IPSS > 8)
• Symptoms impact quality of life significantly
• Complications develop (recurrent urinary tract infections, urinary retention, bladder stones)

Many men have BPH but minimal symptoms and need no treatment.

Medical Treatment for BPH

Alpha-blockers (first-line medication): Block alpha-1 receptors on prostate smooth muscle, relaxing the prostate and improving urine flow.

• Examples: tamsulosin, terazosin, doxazosin
• Onset of action: 1-2 weeks
• Effectiveness: improves symptoms in 60-70% of men
• Side effects: dizziness, orthostatic hypotension (blood pressure drop on standing), retrograde ejaculation

5-alpha reductase inhibitors (second option): Reduce DHT (hormone causing prostate growth), shrinking the prostate over months.

• Examples: finasteride, dutasteride
• Onset: 3-6 months for maximum effect
• Effectiveness: improves symptoms in 50% of men with larger prostates
• Side effects: sexual dysfunction, erectile difficulty, reduced ejaculate volume
• Advantage: reduces prostate cancer risk slightly

Combination therapy: Alpha-blocker plus 5-alpha reductase inhibitor may be used for men with large prostates and moderate-severe symptoms.

Antispasmodics (for urgency): Used if urgency predominates.

Lifestyle modifications:

• Limiting evening fluids
• Avoiding alcohol and caffeine (can worsen symptoms)
• Timing urination (scheduled voids before sleep)
• Pelvic floor exercises (Kegel exercises)
• Double-voiding (urinating twice in succession)

Surgical Treatment for BPH

Surgery is considered if:

• Symptoms are severe and refractory to medication
• Complications have occurred (recurrent urinary retention, infections, stones)
• Patient prefers definitive treatment

Transurethral resection of the prostate (TURP): The standard surgical treatment. A resectoscope (camera and cutting instrument) is inserted through the urethra, and prostate tissue is resected.

• Effectiveness: 90% of men have significant symptom relief
• Recovery: 2-4 weeks
• Complications: temporary incontinence, erectile dysfunction in some men, risk of TURP syndrome (fluid overload) though rare
• Durability: symptoms may recur in 15-20% of men after 10-15 years

Laser prostatectomy: Newer option using laser energy to vaporize prostate tissue.

• Effectiveness: similar to TURP
• Advantages: potentially lower risk of TURP syndrome, faster recovery
• Disadvantages: requires specialized equipment and expertise

Robotic-assisted prostatectomy: Newer option for very large prostates.

• Advantages: precise, good outcomes
• Disadvantages: requires specialized equipment, longer operative time

Most TURP procedures are performed endoscopically without making an external incision (minimally invasive).

Prostate Cancer in Elderly Men

Prostate cancer is the most common cancer in men and second leading cause of cancer death.

Age and incidence:

• Rare before age 50
• Incidence increases with age
• At age 70+, 30-40% of men have prostate cancer on autopsy (many asymptomatic)

Risk factors:

• Age (> 65)
• Family history of prostate cancer
• African ancestry (higher incidence and more aggressive disease)
• Obesity

Prostate Cancer Screening

Screening for prostate cancer is controversial in elderly men:

PSA test (prostate-specific antigen): A blood test measuring PSA, a protein produced by the prostate. Elevated PSA may indicate cancer, BPH, or prostatitis.

Screening recommendations:

• Age 50-69: shared decision-making regarding screening; benefits and risks should be discussed
• Age 70+: routine screening generally not recommended (cancer is slow-growing, treatment risks may outweigh benefit)
• High-risk men (family history, African ancestry): earlier screening discussion (age 40-45)

Limitations of PSA screening:

• Many elevated PSA values are from BPH, not cancer
• Many prostate cancers are slow-growing and will not cause death
• Screening can lead to overdiagnosis and overtreatment
• False positives lead to unnecessary biopsies

Shared decision-making: Your parent should discuss screening with their doctor, weighing:

• Benefits: potential early detection of aggressive cancer
• Risks: false positives, unnecessary biopsies, overtreatment of indolent cancer

Most experts recommend screening discussion rather than routine screening in men over 70.

Prostate Cancer Diagnosis

If PSA is elevated:

Digital rectal exam (DRE): The doctor inserts a finger into the rectum to assess prostate size and texture. Hardness or irregularities raise cancer concern.

Prostate biopsy: If PSA or DRE is concerning, a biopsy is recommended. An ultrasound-guided needle removes tissue samples from the prostate. Results are graded using the Gleason score (6-10; higher = more aggressive).

Prostate Cancer Treatment

For localized, low-grade cancer (limited to prostate, Gleason 6):

• Active surveillance: PSA monitoring without treatment; many slow-growing cancers never require treatment
• Radiation: external beam or brachytherapy
• Surgery: radical prostatectomy (removal of entire prostate)

For intermediate or high-grade cancer (higher Gleason score or PSA):

• Radiation with hormone therapy
• Surgery (in fit patients)

For advanced cancer (spread beyond prostate):

• Hormone therapy (androgen deprivation)
• Chemotherapy in some cases

Treatment selection depends on cancer grade, patient age, overall health, and preferences. In very elderly men with slow-growing cancer, active surveillance is often most appropriate.

Sexual Function and BPH/Prostate Cancer Treatment

Both BPH medications and cancer treatments can affect sexual function:

Erectile dysfunction: Common with 5-alpha reductase inhibitors and in men treated for prostate cancer.

Ejaculatory dysfunction: Alpha-blockers cause retrograde ejaculation (semen enters bladder instead of exiting urethra); not harmful but eliminates ejaculate.

Counseling and management: Doctors can discuss sexual side effects and management options (medications, devices, counseling).

For many elderly men, these side effects are acceptable trade-off for symptom relief or cancer treatment.

Prostatitis: Prostate Infection

Acute bacterial prostatitis causes sudden fever, severe urinary symptoms, and pelvic pain.

Treatment: Antibiotics, typically prescribed for 4 weeks.

Chronic prostatitis: Chronic pelvic pain syndrome with or without bacterial infection; difficult to treat; may require combination therapy (antibiotics, alpha-blockers, anti-inflammatories).

Urinary Incontinence Post-Treatment

Some men develop incontinence after prostate surgery or radiation:

Stress incontinence (leakage with coughing, exercise): most common, usually mild and improves over 6-12 months Urgency incontinence (involuntary leakage with urge to urinate): may develop after radiation

Management: Pelvic floor exercises (Kegel), medications, absorbent pads, or surgical intervention if severe.

Monitoring and Follow-Up

For BPH on medication: Annual assessment of symptom control, PSA check (if being screened for cancer), and medication adjustment as needed.

For men post-prostate surgery: Monitor for incontinence resolution, erectile function recovery, and symptom recurrence.

For men treated for prostate cancer: Regular PSA monitoring, clinical exams, and imaging as indicated based on cancer grade and treatment type.

Lifestyle and Prevention

Potentially protective factors (though not proven):

• Regular exercise
• Healthy diet (Mediterranean-style diet)
• Weight management
• Limiting red meat and dairy
• Adequate selenium and lycopene (antioxidants)

When to Refer to a Urologist

Your parent's primary doctor may recommend urology referral if:

• BPH symptoms are severe or refractory to medication
• PSA is elevated
• Difficulty urinating or urinary retention develops
• Complications (infections, stones, retained urine) occur

Urologists manage BPH surgery and prostate cancer diagnosis and treatment.
