What are the risk factors and management options for Benign Prostatic Hyperplasia (BPH)?

From the Guidelines

Benign Prostatic Hyperplasia (BPH) is primarily managed through lifestyle modifications, medications, and surgical interventions depending on symptom severity, with risk factors including advancing age, family history, obesity, diabetes, heart disease, and lack of physical activity. The management of BPH is multifaceted, involving lifestyle changes, medication, and potentially surgical interventions. Key risk factors for BPH include:

• Advancing age, with the condition being most common in men over 50
• Family history of prostate disease
• Obesity
• Diabetes
• Heart disease
• Lack of physical activity

Management begins with lifestyle changes such as:

• Limiting evening fluid intake
• Reducing alcohol and caffeine consumption
• Avoiding medications that worsen symptoms (like decongestants)
• Implementing scheduled voiding

For medication management, options include:

• Alpha-blockers (tamsulosin 0.4mg daily, alfuzosin 10mg daily, or silodosin 8mg daily) which provide rapid symptom relief by relaxing prostate smooth muscle 1
• 5-alpha reductase inhibitors (finasteride 5mg daily or dutasteride 0.5mg daily) which reduce prostate size over 3-6 months by blocking testosterone conversion to dihydrotestosterone 1
• Combination therapy with both medication classes may be more effective for men with larger prostates, as suggested by the AUA guideline on management of BPH 1
• Phosphodiesterase-5 inhibitors like tadalafil 5mg daily can also improve urinary symptoms, particularly in men with concurrent erectile dysfunction

For patients with persistent symptoms despite medical therapy, minimally invasive procedures (transurethral resection of the prostate, laser therapies, prostatic urethral lift) or open prostatectomy for very large prostates may be necessary. Regular follow-up is essential to monitor symptom progression and medication effectiveness, typically using standardized questionnaires like the International Prostate Symptom Score (IPSS) 1.

Given the most recent and highest quality evidence, the primary approach to managing BPH should focus on a combination of lifestyle modifications and medication, tailored to the individual patient's symptom severity and risk factors, with surgical interventions considered for those with severe symptoms or significant prostate enlargement.

From the Research

Risk Factors for BPH

• Age is a significant risk factor for BPH, as it is a common condition affecting ageing men 2, 3
• Family history, hormonal imbalance, and growth factors are also considered etiological factors in the development of BPH 2, 4
• Dietary and metabolic risk factors, including:
  • Diabetes mellitus 2, 5
  • Hypertension 2, 5
  • Obesity 2
  • Hyperinsulinemia 2
  • Dyslipidemia 2
• Sedentary lifestyle increases the risk of symptoms 5
• Sexual function is also associated with BPH, although the relationship is not fully understood 4

Management Options for BPH

• Medical management, including:
  • Alpha-blockers 6, 5
  • 5-alpha-reductase inhibitors 6, 5
  • Phosphodiesterase-5 inhibitors 5
• Combination therapy with alpha-blockers and 5-alpha-reductase inhibitors may be beneficial for some patients 6, 5
• Self-management methods, such as:
  • Limiting evening fluid intake 5
  • Reducing caffeine and alcohol intake 5
  • Toilet and bladder training 5
  • Pelvic floor exercises 5
  • Mindfulness techniques 5
• Surgical interventions, including transurethral resection of the prostate, may be necessary for some patients 6, 5, 3
