Study Notes
Urinary Tract Infections (UTIs)
- UTIs are infections of the urinary tract, affecting the urethra, bladder, ureters, and/or kidneys
- Lower UTIs involve the urethra and bladder; upper UTIs involve ureters and kidneys
- UTIs are primarily caused by bacteria, most commonly Escherichia coli (E. coli)
- Women experience UTIs more often than men due to a shorter urethra
Types of UTIs (and Symptoms)
- Urethritis (urethra): Burning sensation (dysuria), pain, irritation during urination, possible discharge before or after
- Cystitis (bladder): Dysuria, frequency (urination urges), urgency, pelvic/abdominal pain, possibly blood/foul-smelling urine
- Pyelonephritis (kidneys): Same symptoms as cystitis plus flank pain (side and back pain), fever, chills, nausea, vomiting
Risk Factors for UTIs
- Short urethra (women): Easier bacterial entry
- Proximity to anus (women): Bacteria transfer
- Low fluid intake: Reduced flushing action
- Poor hygiene (women): Improper wiping technique
- Urinary catheters: Introduce bacteria during insertion & use
- Sexual activity: Introduce bacteria
- Age: Women (16-35) and men (over 50) increased risk
- Prostate enlargement (men): Blocking urine flow
- Pregnancy/Menopause: Hormonal changes, immune system changes
- Diabetes: High glucose, altered circulation, suppression immune system
- Bedridden/hospitalization: Reduced mobility, indwelling catheters
Bacteria Causing UTIs
- Escherichia coli (E. coli): Most common cause of UTIs, particularly acute cystitis; part of normal GI flora; uropathogenic E. coli (UPEC) has special virulence factors. (fimbrae, motility)
- Staphylococcus saprophyticus: Second most common cause in sexually active young women; part of the skin/GI/vaginal flora; Coagulase negative and it's resistant to Novobiocin
- Proteus mirabilis: Can form kidney stones due to urease production (increases ammonia, and urine pH thus increasing kidney stone formation); part of normal flora and is motile & has fimbrae
- Leptospira interrogans: Causes leptospirosis; zoonotic (animal-borne); water contaminant, can infect kidneys, liver, brain, and eyes.
UTI Treatment & Prevention
- Antibiotics: Primary treatment
- Frequent urination: Prevents bacterial build-up
- Wiping technique (women): Front-to-back to prevent bacteria from entering urethra
- Hydration: Flushes bacteria from urinary tract
- Cranberry juice: May discourage bacterial attachment
Medical Terminology
- Dysuria: Difficulty/painful urination
- Frequency: Urge to urinate often
- Urgency: Strong urge to urinate immediately
- Hematuria: Blood in the urine
- Cystitis: Bladder infection
- Pyelonephritis: Kidney infection
- Urethritis: Urethra infection
