Epidemiology and Management of UTIs

Study Notes

Epidemiology

Approximately 10 million doctor visits and 100,000 hospital admissions occur annually due to UTIs.
Females are more susceptible to UTIs than males.

Risk Factors

Sexual activity
Diabetes
Poor hygiene
Estrogen deficiency
Recent catheterizations
Foreign objects

Pathophysiology

Bacteria enter the sterile bladder, causing inflammation.

Clinical Manifestations

Bladder irritability
Dysuria (painful urination)
Urinary frequency
Urgency
Urinating small volumes
Gross hematuria (visible blood in urine)
Microhematuria (microscopic blood in urine)
Suprapubic pain

Medical Management - Diagnosis

Diagnosis is based on a combination of clinical manifestations and urine culture results.

Medical Management - Medications

Antimicrobial therapy is used to treat the bacterial infection.
Phenazopyridine (Pyridium) provides symptomatic relief of bladder pain and burning.

Surgical Management

Surgical management may be necessary for patients with known risk factors such as kidney stones, or anatomical defects causing incomplete bladder emptying (e.g., pelvic organ prolapse or enlarged prostate).

Complications

Drug resistance
Pyelonephritis (kidney infection)
Renal abscess (pus-filled cavity in the kidney)

Nursing Management - Assessment and Analysis

Nursing assessments focus on identifying and monitoring clinical manifestations related to the inflammatory process.

Nursing Management - Nursing Diagnoses

Altered urinary elimination
Knowledge deficit regarding UTIs
Acute pain

Nursing Interventions - Assessments

Vital signs
Urinary symptoms
Abdominal examination
Urinalysis
Urine culture

Nursing Interventions - Actions

Administer antibiotics as ordered
Administer bladder analgesics (e.g., phenazopyridine)

Nursing Interventions - Teaching

Instruct patients to report elevated temperature, flank pain, nausea, and vomiting.
Encourage increased fluid intake to help flush out bacteria.
Educate patients on the signs and symptoms of UTIs and preventative measures.
Provide medication education as needed.

Nursing Management - Evaluating Care Outcomes

Ensure the health of the kidneys is protected.
Monitor for resolution of symptoms, indicating successful treatment.

Urinary Tract Infections (UTIs)

Epidemiology: UTI is a common issue with 10 million doctor visits and 100,000 hospital admissions annually
Risk Factors:
- Women are more susceptible to UTIs than men.
- Sexual activity: Increased risk due to introducting bacteria.
- Diabetes: Weakened immune system
- Poor hygiene: Allows bacteria to enter the urethra.
- Estrogen deficiency: Changes in vaginal flora.
- Recent catheterizations: Introduces bacteria.
- Foreign objects: In the urinary tract.
Pathophysiology:
- Bacteria enter the bladder, leading to inflammation.
Clinical Manifestations:
- Bladder irritability: Frequent urination, urgency and dysuria.
- Dysuria: Painful urination.
- Urinary frequency: Frequent urination.
- Urgency: Strong urge to urinate.
- Urinating small volumes: Small amounts of urine are passed.
- Gross hematuria: Visible blood in the urine.
- Microhematuria: Blood in the urine visible only under a microscope.
- Suprapubic pain: Pain in the lower abdomen.
Medical Management:
- Diagnosis: Clinical symptoms and urine culture.
- Medications:
  - Antimicrobial therapy: To treat the bacterial infection.
  - Phenazopyridine: To relieve pain during urination.
Surgical Management:
- Considered for patients with:
  - Kidney stones: Obstructing urine flow.
  - Anatomical defects: Leading to incomplete bladder emptying (pelvic organ prolapse or enlarged prostate).
Complications:
- Drug resistance: To antibiotics.
- Pyelonephritis: Kidney infection.
- Renal abscess: Pus collection in a kidney.
Nursing Management:
- Assessment & Analysis:
  - Monitor patients for signs of inflammation,
- Nursing Diagnoses:
  - Altered urinary elimination: Due to infection.
  - Knowledge deficit: About UTI.
  - Acute pain: Associated with UTI.
- Nursing Interventions:
  - Assessments:
    - Vital signs: Temperature, heart rate, blood pressure.
    - Urinary symptoms: frequency, urgency, dysuria.
    - Abdominal examination: Palpate for tenderness.
    - Urinalysis: To detect infection.
    - Urine culture: To identify the infecting bacteria.
  - Actions:
    - Administer antibiotics: As prescribed.
    - Administer bladder analgesics: To relieve pain.
  - Teaching:
    - Report elevated temperature, flank pain, nausea and vomiting: Possible signs of pyelonephritis.
    - Increase fluid intake: To flush out bacteria.
    - Signs and symptoms of UTI: To identify the infection early.
    - UTI prevention: To reduce risk of future infections.
    - Medication education: Dosage, side effects, and how to take medications.
- Evaluation of Care Outcomes:
  - Health of kidney is protected: Infection is resolved.
  - Resolution of symptoms: Relief from pain and improved urinary function.
