    Study Notes

    Urinary Tract Infection (UTI)

    • UTI is defined as the presence of microorganisms in the urine, not due to contamination.
    • Lower UTI includes cystitis (bladder), urethritis (urethra), prostatitis (prostate gland), and epididymitis.
    • Upper UTI involves the kidneys and is referred to as pyelonephritis.
    • Uncomplicated UTI occurs in patients with normal urinary tracts, such as cystitis and pyelonephritis.
    • Complicated UTI occurs in patients with a risk of infection in the urinary tract, like those with stones, congenital abnormalities, obstruction, prostate hypertrophy, or neurological deficits.
    • Recurrent UTIs are three or more UTIs within one year, and are due to reinfection or relapse.
    • Relapse is repeated infections by the same initial organism.
    • Symptomatic abacteriuria (acute urethral syndrome) has UTI symptoms but few bacteria in the urine.
    • Asymptomatic bacteriuria finds significant bacteria in the urine without symptoms.

    UTI Pathogenesis

    • UTI can enter the urinary tract through hematogenous (blood) or ascending pathways.
    • In most UTIs, the bacteria ascend from the urethra to the bladder.
    • The female urethra is shorter, making females more susceptible to UTI.
    • Sexual activity can increase the risk of UTI in females.
    • Anything hindering urine flow (e.g., structural issues, prostate enlargement) raises the risk.

    UTI Risk Factors

    • Age (risk increases after 50, men more likely due to prostate problems.)
    • Underlying conditions
    • Diabetes
    • Pregnancy (decreased ureteral peristalsis during pregnancy.)
    • Immunosuppression
    • Urinary tract obstruction

    UTI Diagnosis

    • Urine analysis (detects pyuria, hematuria, bacteria)
    • Urine culture (gold standard, checks organism and its susceptibility to treatment)

    UTI Treatment

    • Antimicrobial therapy is the cornerstone.
    • Analgesics (like phenazopyridine) manage pain.
    • Treat uncomplicated cystitis (frequent UTI in women) with short-course antibiotics.
    • Complicated UTIs (severe) often need intravenous antibiotics and longer durations (14 days).
    • Referrals to doctors for more complex issues.

    Asymptomatic Bacteriuria

    • Management depends upon patient age, pregnancy status, and if female.
    • Treatment with antibiotics may not significantly affect the disease course.
