Module 1: Vascular and Genitourinary Conditions (BPH & Prostate Cancer) Flashcards
Benign Prostatic Hyperplasia (BPH)
Age-associated prostate gland enlargement that can cause urination difficulty
Epidemiology: Effects individuals equally across race
Diagnosis:
- Based on symptoms
- Confirmed with digital rectal examination (DRE) in men >40 yrs. old
- Prostate specific antigen (PSA) blood test — considered a tumor marker (may also be present with infection/inflammation)
Complications:
- Acute urinary retention
- Bladder stones
- Infection
- Hydronephrosis
- Postrenal AKI (obstruction in the urinary tract below the kidneys causing waste to build up in the kidneys)
- Pyelonephritis
BPH: Clinical Manifestations
Lower urinary tract CMs of BPH:
- Difficulty starting flow of urine, even while straining
- Weak stream of urine
- Multiple interruptions during urination
- Dribbling once urination is complete
Bladder changes (related to fluid retention):
- Urinary urgency or frequency
- Feeling of not emptying the bladder
- Incontinence
- Nocturia
BPH: Management & Treatments
Management of patients with BPH (“Watchful waiting” if symptoms do not interfere ADLs):
- Yearly DRE
- Avoid tranquilizers and OTC decongestants (worsen symptoms) — tighten muscles in the prostate and bladder neck
- Avoid excess fluids in the evening to decrease nocturia
Meds. (Improve symptoms 30-60% of the time):
- 5-alpha reductase inhibitor admin. (inhibits metabolism of testosterone into DHT; DHT stimulates growth factors and prostatic hyperplasia) — takes 3-6 mos. to see effectiveness; Does not work on circulating testosterone (patients do not need to worry about impotence)
- Alpha blockers admin. — promote smooth muscle relaxation; takes 2 weeks-4 mos. to see effectiveness
Alternative therapies:
- Intermittent catheterization
- Long-term indwelling catheterization (changed monthly)
- Saw palmetto
Surgical management: Transurethral resection of the (inner) prostate (TURP); most common BPH surgery
BPH: Nursing Assessment & Interventions
Nursing assessment of patients with BPH:
- Urinary symptoms (subjective data)
- Temp. — possible infection
- Focused abdominal examination
- Bladder scan — evaluate for urinary retention
- Urinalysis — diagnostic signs of stones or infection
Interventions for patients with BPH:
- Indwelling catheter care
- Med. admin. as ordered
BPH education:
- “Watchful waiting”
- Decrease fluid intake in the evening (prevent nocturia)
- Drug therapy education
- Follow-up adherence
- Surgical options
- Post-surgical care
Postate Cancer
Slow growing cancer, generally in the periphery of the prostate; possible metastasis to lymph nodes, lungs, and bone
Diagnosis:
- Yearly DRE beginning at age 45-50
- PSA blood test — false negative or false positive (due to infection/inflammation)
- Biopsy
Risk factors:
- FHX
- Age >55 yrs.
- Diet low in fruits and vegetables
Epidemiology:
- Most common CA in males
- 9% of CA deaths in males
- Risk/occurrence for transgender women depends on age hormone therapy commenced (hormone therapy after >50 yrs. old is NOT protective)
Prostate Cancer: Clinical Manifestations
CMs:
1. Many patients are asymptomatic
- Symptoms mimic BPH as CA progresses — i.e. Weak urinary stream, hesitancy, frequency, urgency, and incontinence
- “Hallmark” S/S: Hematuria and hemospermia
- Pain
- Rectal symptoms — i.e. Rectal pain/cramping, tenesmus (feeling of incomplete defecation)
Prostate Cancer: Management
Medical management of prostate CA:
- Hormonal ablation therapy (suppresses testosterone) — shrinks prostate prior to radiation
- Chemotherapy (PO or IV) — refractory to hormone ablation therapy in advanced prostate CA
Non-surgical management of prostate CA:
- External beam radiation
- Brachytherapy: radioactive capsule is implanted through the perineum into the prostate and is left permanently — Abstain from sex for 2 weeks and use condoms thereafter to prevent radiation exposure
- Cryotherapy: freezes prostatic cancerous tissue
Surgical management of prostate CA:
1. Radical prostatectomy: prostate and seminal vesicles are removed (open or laparoscopic); may remove lymph nodes — Almost always results in impotence (“nerve sparing” procedures are emerging)
Prostate Cancer: Nursing Assessment & Interventions
Nursing assessment of patients with prostate CA:
- Risk factors
- PSA blood test (>4 requires further assessment)
- DRE results
- Urinary symptoms — i.e. Weak stream, distended bladder, etc.
Interventions of patients with prostate CA:
- Med. admin. as ordered
- Post-surgical wound care
- Stool softener admin.
Education:
- Treatment options
- Signs of infection
- Prevention/screening
