Male Reproductive Disorders: Prostatitis and Benign Prostatic Hyperplasia (BPH)

Prostatitis: Overview and Pathophysiology

• Definition: Prostatitis is the inflammation of the prostate gland.
• Classification Types:     * Acute Bacterial: Sudden onset of prostate inflammation caused by bacteria.     * Chronic Bacterial: Recurrent bacterial infection and inflammation of the prostate.     * Chronic Prostatitis / Chronic Pelvic Pain Syndrome: Characterized by pelvic pain with or without inflammation, in the absence of a confirmed bacterial infection.     * Asymptomatic Inflammatory: Inflammation found in the absence of symptoms, often during evaluations for other conditions.
• Etiology and Microorganisms:     * Microorganisms are typically found in the prostatic fluid.     * Escherichia coli ($E.coli$): The most common causative organism for bacterial prostatitis.     * Other factors include nonbacterial urethral strictures and prostatic hyperplasia.

Clinical Manifestations and Diagnosis of Prostatitis

• Clinical Presentation: Patients may present with various signs and symptoms including pelvic pain, urinary frequency, and systemic signs if the infection is acute bacterial.
• Diagnostic Procedures:     * Patient History: Detailed account of symptoms and their duration.     * Culture of Prostatic Fluid: To identify specific pathogens.     * Histologic Tissue Exam: Microscopic examination of prostate tissue.     * Urinalysis ($UA$) and Culture and Sensitivity (C&S): Used to rule out or confirm concurrent urinary tract infections.     * Digital Rectal Exam ($DRE$): Physical examination of the gland's size, shape, and tenderness.     * Cystoscopy: Visual examination of the bladder and urethra.

Professional Management of Prostatitis

• Medical Management:     * Acute/Broad Spectrum Antibiotics: Administered intravenously ($IV$) or orally for typically $10-14$ days.     * $NSAIDs$: Used for pain and inflammation.     * Comfort Care: Bed rest and sitz baths to soothe the area.     * Chronic Management:         * Long-term use of $NSAIDs$.         * Alpha-blockers: Specifically Flomax ($Tamsulosin$) to relax smooth muscle.         * Supportive therapy: Prostatic massage or ejaculation to help clear secretions.
• Nursing Management and Patient Education:     * Medication Administration: Includes Flomax, $NSAIDs$, Antibiotics ($ATB$), and stool softeners.     * Symptom Education: Informing the patient that the condition is not contagious.     * Medication Precautions: Instruct patients to avoid medications that cause urinary retention, specifically:         * Decongestants.         * Antihistamines.     * Dietary Restrictions: Advise the patient to avoid spicy foods.

Benign Prostatic Hyperplasia (BPH): Pathophysiology and History

• Definition: BPH involves glandular units in the prostate undergoing nodular tissue hyperplasia, leading to the enlargement of the prostate gland.
• Result: This enlargement causes Bladder Outlet Obstruction ($BOO$).
• Pathophysiology:     * As the prostate tissue expands, the urethra is compressed and narrowed.     * The symptoms are a direct result of the narrowing of the prostatic portion of the urethra.
• Etiology:     * The exact cause is not fully understood.     * Rationale: The current understanding links BPH to increased levels of testosterone that occur normally with increasing age.
• International Prostate Symptom Score ($I-PSS$):     * This is a validated tool for physical and psychosocial assessment based on symptoms over the past month.     * Categories Assessed (Scored 0-5):         1. Incomplete Emptying: Sensation of the bladder not being empty.         2. Frequency: Urinating less than every $21$ hours.         3. Intermittency: Stopping and starting several times during urination.         4. Urgency: Difficulty postponing urination.         5. Weak Stream: Poor force of the urinary stream.         6. Straining: Struggling to begin urination.         7. Nocturia: Number of times waking up at night to urinate (Scored $0-5$ based on number of times).     * Scoring Thresholds:         * $1-7$: Mild symptoms.         * $8-19$: Moderate symptoms.         * $20-35$: Severe symptoms.     * Quality of Life Question: Asks how the patient would feel about spending the rest of their life with their current urinary condition (range: Delighted to Terrible).

Diagnostic Testing for BPH and Prostate Health

• Digital Rectal Exam ($DRE$).
• Urinalysis ($UA$) with Culture and Sensitivity (C&S).
• Serum Creatinine and Blood Urea Nitrogen ($BUN$): To assess renal function influenced by obstruction.
• Prostate Specific Antigen ($PSA$): To screen for prostate cancer.
• Complete Blood Count ($CBC$).
• C&S of Prostatic Fluid.
• Urodynamic Testing: Includes uroflowmetry, cystometry, and pressure-flow studies.
• Prostate Ultrasound: Either transabdominal or Transrectal Ultrasound ($TRUS$).
• Cystoscopy: Direct visualization (refer to Chapter 65 for detailed description).

Medical and Surgical Management of BPH

• Medication Therapy:     * Alpha-receptor Blockers: Examples include Hytrin ($Terazosin$), Doxazosin, and Flomax ($Tamsulosin$). These relax the smooth muscle in the bladder neck and prostate and constrict the prostate.     * 5-alpha-reductase Inhibitors: Examples include Finasteride ($Proscar$). These decrease hormonal activity (specifically dihydrotestosterone or $DHT$) to shrink the prostate gland.
• Minimally Invasive Surgical Techniques:     * Transurethral Microwave Thermotherapy ($TUMT$): Deliverance of microwave energy via an intraurethral catheter (ThermoCath). It incorporates a microwave generator/antenna, temperature measurement, and a cooling system to protect the urethra from heat damage.
• Transurethral Resection of the Prostate ($TURP$):     * A surgical procedure where a resectoscope is used to remove prostate tissue clogging the urethra.

Nursing Management for Prostate Surgery and Post-Operative Care

• Pre-operative Goals:     * Assess the patient's knowledge regarding the surgery.     * Provide education to the patient and family.
• Post-operative Nursing Priorities:     * Vital Signs ($VS$): Frequent assessment for the first $24$ hours.     * Intake and Output (I&O): Maintain accurate records.     * Continuous Bladder Irrigation ($CBI$): Use of a 3-way catheter with an inflated $30-45\,mL$ balloon. Use antibacterial/isotonic irrigation solution to prevent clots.     * Medication Administration:         * Antibiotics ($ATB$): Transition from $IV$ to $PO$.         * Pain medications: Narcotics for severe pain.         * Antispasmodics: Such as Ditropan ($Oxybutynin$) for bladder spasms.         * Oral Urinary Analgesic: Pyridium ($Phenazopyridine$).     * Warning: Avoid anticoagulants during the recovery phase to prevent bleeding.
• Common Post-Op Symptoms:     * Abdominal pain and cramps.     * Bladder Spasms: Characterized by a strong urge to void and urine leakage around the catheter.

Case Study: 74-Year-Old Male with Obstructive Symptoms

• Presentation: Difficulty starting urine stream, sensation of incomplete emptying, and post-void dribbling.
• Assessment Questions: The nurse should use the $I-PSS$ to quantify the severity of symptoms.
• Expected Diagnosis: Benign Prostatic Hyperplasia ($BPH$).
• Clinical Findings: The nurse anticipates finding a distended bladder due to urinary retention.
• Medication Teaching (Finasteride/Proscar):     * The nurse should explain that it will decrease the level of dihydrotestosterone ($DHT$) and shrink the prostate.     * It does not cause postural hypotension (this is an effect of alpha-blockers like Flomax).
• Post-TURP Priority Interventions:     * Assess for signs of infection.     * Check urine output every $2\,hours$.     * Remind the patient that urine will be blood-tinged (normal post-op finding).     * Administer pain and antispasmodic drugs as needed.     * Note: Extended bed rest for 2 days is generally not recommended as early ambulation is preferred.
