Benign prostatic hyperplasia (BPH) is a common urinary condition that develops in aging men due to non-cancerous enlargement of the prostate gland. As the prostate grows bigger, it constricts the urethral channel running through it, leading to bothersome lower urinary tract symptoms. While not life-threatening, symptoms can negatively impact one’s lifestyle.

This in-depth guide covers all key facets of BPH to help better understand and manage this prevalent condition.

What Exactly is Benign Prostatic Hyperplasia?

The prostate is a walnut-sized gland located underneath the bladder in males that contributes to semen and sperm production. The outer peripheral zone comprises 70% while the inner transition zone makes up 5% of overall prostate volume.

Benign prostatic hyperplasia specifically involves proliferation of cells in the inner transitional zone, causing this region to expand. As more tissue accumulates, the enlarged gland begins compressing the urethra traversing through the prostate’s center to exit urine.

Over time, this causes a partial blockage or stricture that inhibits normal urine flow and drainage. The bladder muscle also hypertrophies in response, further adding pressure.

Names and Terminology Associated With BPH

Several terms relate to the structural growth of prostate tissue leading to urinary dysfunction:

• Benign Prostatic Enlargement (BPE)
• Benign Prostatic Obstruction (BPO)

These names all denote the same progressive, benign overgrowth of the prostate compressing on and partially obstructing the urethra’s lumen.

Distinguishing BPH From Prostate Cancer

Prostate cancer denotes malignant, invasive tumor growth that can spread to other organs. Thus, it warrants more aggressive treatment. BPH represents localized overgrowth typically responsive to medications or minimally invasive procedures for symptom relief. However, some data suggests that long-term BPH may increase susceptability to developing prostate cancer later on as well.

Prevalence and Risk Factors for Developing BPH

Symptomatic BPH is uncommon in those under age 40 but manifests increasingly in older males. Global prevalence approximates:

• 50% of men in their 50s
• 70% of men in their 60s
• Over 80% beyond age 80

Regional differences exist as well, with more occurrences in Western/European descended populations compared to Asian groups.

Various factors also raise one’s risk:

Non-Modifiable Factors

• Age – cleavage of prostatic testosterone rises
• Family History – hereditary androgen sensitivity

Modifiable Factors

• High body mass index (BMI)
• Metabolic syndrome
• Smoking
• Sedentary lifestyle

Concentrating preventive efforts toward alterable risks holds promise for reducing symptomatic onset.

What Are Common BPH Symptoms and Signs?

As benign prostate enlargement imposes increasing mechanical compression on the urethra, a number of lower urinary tract symptoms emerge including:

• Weak, inconsistent urinary stream
• Straining to urinate
• Dribbling after finishing
• Sudden need to urinate urgently
• Frequently waking at night to urinate (nocturia)

With continual obstruction over months to years, secondary issues like recurrent UTIs, blood in the urine, bladder stones, bladder wall thickening, and even kidney impairment may manifest as well.

Tracking symptom severity with questionnaires like the International Prostate Symptom Score (IPSS) index helps gauge therapeutic timing and efficacy.

Why BPH Symptoms Fluctuate

BPH related urinary symptoms often wax and wane over periods of time. Reasons include:

• Periods of prostate inflammatory swelling
• Bladder spasms
• Fluid status hydration changes

Understanding this known variability aids long term disease management.

Evaluating and Diagnosing Benign Prostatic Hyperplasia

Confirming a BPH diagnosis relies upon assessing history, physical examination findings, urinalysis studies, and prostate imaging.

Initial Screening Evaluation

Preliminary evaluation begins with:

• Detailed voiding history
• Digital rectal exam of the prostate

Signs concerning for BPH include weak/intermittent stream, straining, nocturia, and an enlarged, swollen feeling gland on rectal examination.

Urinalysis and PSA Blood Testing

Laboratory urinalysis checks for signs of infection including white blood cells and bacteria. This helps rule out other causes of urinary irritation.

Checking serum prostate-specific antigen (PSA) levels may provide adjunct correlation to prostate volume. However, many other factors also influence PSA.

Visualization With Medical Imaging

• Transrectal ultrasound visually characterizes prostate anatomy.
• Bladder/urethral cystoscopy thoroughly examines changes.
• Post-void residual bladder volume measurement via ultrasound assesses urinary retention.

Comparison against prior imaging demonstrates structural changes and progression over time. Follow-up monitoring further helps gauge treatment efficacy by assessing anatomy modifications.

Who Is on the BPH Care Team?

Managing benign prostatic hyperplasia requires an interprofessional team approach, typically including:

• Primary care physician
• Urologist specialists
• Nurses
• Physical therapists

Primary doctors coordinate initial testing and examinations. Urology specialists conduct cystoscopy procedures and prostate surgeries while managing complex medication regimens. Nurses assist with post-surgical catheter care. Physical therapists provide pelvic floor muscle strengthening guidance.

Smooth referrals across this multi-faceted care team ensures prompt diagnosis and appropriate therapy.

Overview of Management Approaches for BPH

Multiple treatment options exist spanning from watchful waiting to medications to various minimally invasive procedures to surgeries depending on symptom severity and prostate size.

Conservative Monitoring Approaches

Mild or intermittent symptoms may warrant conservative monitoring including:

• Routine tracking of voiding patterns
• Recording symptom severity scores
• Periodic prostate exams and PSA testing

Adopting healthy lifestyle changes like dietary adjustments, weight control, and kegel pelvic exercises may also help stabilize or slow progression. If symptoms remain tolerable, this noninvasive approach avoids medication side effects.

Oral Medications for BPH Symptom Relief

If bothersome symptoms persist, daily medications to shrink prostate tissue or relax muscles can provide relief. Types include:

Alpha blockers to relax smooth muscle tension around the urethra. These rapidly improve urine flow rate. Examples include tamsulosin and alfuzosin.

5-alpha reductase inhibitors to induce prostate cell death and slow continued growth. These gradually shrink prostate size over 6-12 months. The oral drug dutasteride inhibits both types 1 and 2 reductase enzymes for additive effects.

Combining both classes offers superior improvements in urinary flow rates and symptom scores based on clinical studies.

Interventional Procedures for BPH

If medications prove intolerable or inadequate, several office-based therapeutic procedures offer direct prostate tissue reduction. Options include:

Transurethral microwave thermotherapy – using heat generated by a microwave antenna placed within the prostate to destroy outer tissue.

Transurethral needle ablation (TUNA) – utilizing radiofrequency energy applied through twin needles directly into the prostate.

Prostatic urethral lift – opens the collapsed urethra using permanent implants to retract prostate lobes.

These technologies provide rapid localized tissue necrosis with several weeks’ recovery, but less morbidity than traditional surgeries.

Surgical Interventions for BPH

Most invasive transurethral and open surgeries resection larger prostate volumes and shorter procedure times yet require prolonged catheterizations.

Transurethral Resection of Prostate (TURP) – endoscopic electrocautery loop cuts away inner prostate overgrowth pressing on urethra. This longtime “gold standard” option remains the surgery with greatest experience.

Photoselective Laser Vaporization of Prostate utilizes laser destruction which elicits less bleeding given the cauterization effects. Often employed for very large glands.

Ultimately for advanced disease, open prostatectomy surgeries offer complete enucleation but with extensive convalescence. Newer laser modalities continue to emerge as well.

Comparing Management Options for BPH

Emerging and Experimental Therapies

With increasing research, new modalities aim to balance invasiveness, efficacy, and recovery even further. These include prostatic stents to physically hold the urethra open and novel laser techniques like Diode and Holmium variants.

Gene and cellular therapies even look to reverse hyperplastic prostate growth altogether.

Follow Up Care for BPH

Long term surveillance helps gauge treatment efficacy and early detection of recurrent urinary obstruction. Follow-up after interventions includes:

1. Reviewing symptom score trends – is voiding easier, urgency resolved?

2. Interval medical imaging – shrinking prostate size?

3. Uroflowmetry – increased peak urine flow?

4. Post-void residual volume measurement – less urinary retention?

Follow up spans anywhere from monthly, biannually, to annually based on baseline severity and type of procedure performed. Continued care aims to optimize health and avoid BPH progression.

Impacts and Complications of BPH

If left completely untreated, benign prostatic hyperplasia can lead to several complications over 5-10 years:

• Acute complete urinary retention requiring emergent catheterization
• Recurrent urinary tract infections, urosepsis
• Bladder distension, thickening and poor compliance
• Eventual renal insufficiency

This further emphasizes the importance of active surveillance and timely intervention aligned with symptom severity before permanent bladder or kidney sequelae develop. Therapies to reduce prostate obstruction safeguards overall health.
