Study Notes

Types of Urinary Tract Infections (UTIs)

Lower UTIs include cystitis, prostatitis, and urethritis.
Upper UTIs consist of acute pyelonephritis, chronic pyelonephritis, renal abscess, interstitial nephritis, and perirenal abscess.
Uncomplicated UTIs are generally community-acquired, common among young women, and rarely recurrent.
Complicated UTIs are often nosocomial, associated with catheterization, and occur in individuals with urologic abnormalities, pregnancy, immunosuppression, diabetes, and obstructions.

Risk Factors for UTIs

Incomplete bladder emptying can lead to infections.
Obstruction can be caused by congenital abnormalities, strictures, bladder neck contracture, tumors, calculi, or ureter compression.
Immunosuppression or underlying conditions (e.g., diabetes, pregnancy) increase vulnerability.
Instrumentation of the urinary tract presents a risk, alongside inflammation or irritation of the urethra.

Prevention Mechanisms Against UTIs

Urination flushes bacteria from the urethra.
In females, mucus in the urethra traps bacteria; in males, the length of the urethra and prostate secretions offer protection.
High osmolality and low pH of urine, alongside uromodulin and urinary tract epithelial cells, contribute to bactericidal activity.
The ureterovesical junction acts as a one-way valve, preventing ascent of urine into upper urinary tract.
The urethral sphincter blocks upward movement of bacteria.

Immune Response

Toll-like receptors (TLR4) detect pathogens, recruiting neutrophils and macrophages for phagocytosis.
Infection potential depends on both the pathogen's virulence and the individual's immune response.

Medications for UTIs and Pyelonephritis

Cephalexin (Keflex) - Genitourinary infections.
Ampicillin (Principen) - UTI and pyelonephritis, not commonly used alone due to E. coli resistance.
Amoxicillin (Amoxil) - UTI and pyelonephritis, similar resistance issues as ampicillin.
Trimethoprim-sulfamethoxazole (Bactrim Septra) - UTI and pyelonephritis.
Nitrofurantoin (Macrodantin) - UTI.
Ciprofloxacin (Cipro) - UTI and pyelonephritis.
Levofloxacin (Levaquin) - Uncomplicated UTI.
Phenazopyridine (Pyridium) - Alleviates burning and pain associated with UTI.

Nursing Process for Lower UTIs

Assessment: Look for symptoms such as pain, urgency, frequency, and urine characteristics.
Diagnosis: Identify acute pain and deficient knowledge about preventive measures.
Planning: Set goals for pain relief and knowledge enhancement on UTIs.
Intervention: Provide pain relief, monitor complications, and educate on care and prevention.

Patient Education: Urodynamic Testing

In-depth discussions about urologic symptoms to prepare the patient.
Patients may experience discomfort from catheters and position changes.
Encouraged to avoid caffeine and irritants post-procedure and stay alert for UTI symptoms.

Preventing Recurrent UTIs

Maintain proper hygiene by showering and wiping front to back after bowel movements.
Increase fluid intake to flush out pathogens; avoid irritants like caffeine and alcohol.
Practice regular voiding habits, emptying the bladder entirely.
Follow prescribed medications strictly and consider urinary acidification with vitamin C or cranberry juice to prevent recurrence.

Upper Urinary Tract Infection: Acute vs. Chronic Pyelonephritis

Acute Pyelonephritis: Severe bacterial infection with symptoms like chills, fever, flank pain, nausea, and vomiting; can lead to renal scarring.
Chronic Pyelonephritis: May show no symptoms unless exacerbated; potential symptoms include fatigue, poor appetite, and polyuria.

Causes of Incontinence: DIAPPERS

Delirium
Infection of the urinary tract
Atrophic vaginitis and urethritis
Pharmacologic agents affecting bladder control
Psychological factors
Excessive urine production
Restricted activity
Stool impaction

Urinary Retention

Defined as inability to completely empty the bladder, potentially leading to overflow incontinence.
Residual urine can increase with age; in older adults, 50-100 mL may remain post-voiding.
Causes include diabetes, prostatic enlargement, trauma, or neurologic disorders.

Strategies for Promoting Urinary Continence

Monitor fluid intake and avoid diuretics late in the day.
Stay aware of bladder irritants and maintain regular bowel habits to prevent constipation.
