What does UTI stand for?
Urinary Tract Infection
Upper Tract Inflammation
Urethral Tract Issue
Urinary Transient Infection
UTI stands for urinary tract infection, which is an infection of any part of the urinary system including kidneys, ureters, bladder, or urethra. It's the standard medical abbreviation used globally. Prompt recognition of UTI is important for appropriate treatment. .
Which organism is the most common cause of community-acquired UTIs?
Pseudomonas aeruginosa
Enterococcus faecalis
Staphylococcus aureus
Escherichia coli
Escherichia coli is responsible for approximately 80 - 90% of community-acquired UTIs due to its ability to colonize the periurethral area and ascend the urinary tract. Other bacteria are less common in uncomplicated infections. Identifying the causative organism guides appropriate antibiotic therapy. .
Dysuria refers to which symptom?
Painful urination
Frequent urination
Blood in urine
Urine retention
Dysuria is defined as pain or burning during urination and is a hallmark symptom of lower urinary tract infections. While frequency and hematuria can accompany dysuria, the term specifically refers to discomfort on voiding. Proper symptom assessment helps clinicians differentiate between types of urinary conditions. .
Which organ is not part of the urinary tract?
Kidney
Urethra
Spleen
Bladder
The urinary tract consists of the kidneys, ureters, bladder, and urethra. The spleen is part of the lymphatic and immune systems and has no role in urine production or storage. Understanding anatomy is crucial for localizing infections. .
Which population is at highest risk for developing UTIs?
Children under one year
Competitive athletes
Elderly men
Women
Women are more prone to UTIs due to a shorter urethra and closer proximity of the urethral opening to the anus, which facilitates bacterial ascent. While infants and elderly men can also develop UTIs, the female anatomy and hormonal factors increase risk significantly. .
Which test is commonly used as an initial screening for a suspected UTI?
Blood culture
MRI of the kidneys
CT scan of the abdomen
Urinalysis with dipstick
A urinalysis with dipstick testing for leukocyte esterase and nitrites is the primary screening tool for UTIs because it is rapid and noninvasive. Positive dipstick results are followed by microscopic analysis and culture for confirmation. Imaging studies are reserved for complicated cases. .
Pyuria indicates the presence of what in urine?
Glucose
Red blood cells
White blood cells
Bacteria
Pyuria is defined as the presence of white blood cells (WBCs) in the urine, reflecting inflammation of the urinary tract. It often accompanies urinary tract infections but can occur in other inflammatory conditions. Microscopic analysis of urine confirms pyuria. .
Which of the following is classified as an upper urinary tract infection?
Cystitis
Urethritis
Prostatitis
Pyelonephritis
Pyelonephritis is an infection of the kidney and upper urinary tract, often presenting with fever, flank pain, and systemic symptoms. Cystitis and urethritis affect lower urinary structures, while prostatitis affects the prostate gland. Accurate classification guides treatment intensity. .
In women, a urine culture showing more than what threshold of colony-forming units per milliliter is considered significant bacteriuria?
10? CFU/mL
10? CFU/mL
10? CFU/mL
10? CFU/mL
Significant bacteriuria is traditionally defined as ?10? CFU/mL on a clean-catch urine sample in women. Lower thresholds may apply when patients are symptomatic or catheterized. This cutoff helps distinguish contamination from true infection. .
Which dietary supplement has been shown to help prevent recurrent UTIs by inhibiting bacterial adhesion?
Cranberry extract
Probiotics
Green tea extract
Vitamin C
Cranberry products contain proanthocyanidins that inhibit the adhesion of E. coli to the bladder wall, reducing the risk of recurrent UTIs. While other supplements have been studied, cranberry extract has the most consistent evidence. .
What is the first-line antibiotic for uncomplicated cystitis in nonpregnant women?
Cephalexin
Amoxicillin
Nitrofurantoin
Ciprofloxacin
Nitrofurantoin is preferred for uncomplicated cystitis in nonpregnant women due to its efficacy, low resistance rates, and minimal collateral damage to flora. Fluoroquinolones and broad-spectrum cephalosporins are reserved for resistant or complicated cases. .
Asymptomatic bacteriuria typically requires antibiotic treatment in which group?
Elderly nursing home residents
Postmenopausal women
Young adult males
Pregnant women
Treatment of asymptomatic bacteriuria is indicated in pregnant women to prevent pyelonephritis and adverse pregnancy outcomes. In other populations, routine treatment is not recommended due to lack of benefit and potential harm from antibiotics. .
What defines a recurrent urinary tract infection?
Two or more infections within six months
One infection per year
Two infections in one year
Three infections in two years
Recurrent UTI is defined as two or more symptomatic infections within six months or three or more within a year. Recognizing this pattern prompts evaluation for underlying abnormalities and prophylactic strategies. .
Indwelling urinary catheters increase UTI risk primarily by facilitating bacterial:
Biofilm formation
Toxin production
Immune complex deposition
Antibody degradation
Catheters provide a surface for bacteria to adhere and form biofilms, which protect microbes from host defenses and antibiotics. Biofilms are a major cause of catheter-associated UTIs. Preventing biofilm formation is key to reducing infection. .
In men, a urinary tract infection is often associated with infection of the:
Epididymis
Prostate gland
Renal pelvis
Seminal vesicles
In men, UTIs often involve the prostate (prostatitis), due to reflux of infected urine into prostatic ducts and zonal anatomy. Isolated bladder infections are less common in males, and prostatitis can be acute or chronic. .
Trimethoprim-sulfamethoxazole works by inhibiting sequential enzymes in which bacterial pathway?
Protein synthesis
Folate synthesis
Cell wall synthesis
DNA replication
The combination of trimethoprim and sulfamethoxazole blocks two sequential steps in the folate synthesis pathway, preventing bacterial DNA synthesis. Sulfamethoxazole inhibits dihydropteroate synthase, while trimethoprim inhibits dihydrofolate reductase. This synergy enhances efficacy. .
Why are fluoroquinolones generally avoided as first-line UTI treatment in children?
Risk of tendon damage
Hemolytic anemia risk
Retinal toxicity
Potential hearing loss
Fluoroquinolones carry a risk of musculoskeletal toxicity, including tendonitis and tendon rupture, particularly in pediatric patients. Due to these safety concerns, they are reserved for cases without alternatives. .
Uropathogenic E. coli adhere to urothelial cells using which virulence factor?
Lipoteichoic acid
FimH adhesin
Protein A
M protein
FimH is an adhesin located at the tip of type 1 pili on E. coli, mediating binding to mannose residues on urothelial cells. This adhesion is critical for colonization and biofilm formation. .
Which clinical sign is more indicative of acute pyelonephritis rather than cystitis?
Urinary frequency
Dysuria
Flank pain and fever
Gross hematuria
Acute pyelonephritis involves renal parenchyma and typically presents with fever and flank pain, unlike cystitis which is confined to the bladder and presents primarily with lower urinary symptoms. Systemic features help distinguish severity. .
A long-term complication of recurrent pyelonephritis can be:
Prostatic hypertrophy
Urethral stricture
Bladder carcinoma
Renal scarring
Repeated kidney infections can lead to permanent renal scarring, which may result in hypertension and chronic kidney disease. Early diagnosis and appropriate treatment of pyelonephritis help prevent scarring. .
Interstitial cystitis differs from bacterial UTI because it typically:
Responds rapidly to antibiotics
Presents with high fever
Has negative urine cultures despite symptoms
Occurs only in males
Interstitial cystitis (painful bladder syndrome) presents with urinary urgency and frequency like a UTI but urine cultures remain negative because no bacterial infection is present. Antibiotics are ineffective in this condition. .
D-mannose is thought to prevent UTIs by:
Acidifying the urine
Stimulating systemic immunity
Binding to bacterial pili and inhibiting adhesion
Increasing urinary output
D-mannose molecules bind to FimH adhesins on E. coli pili, preventing the bacteria from attaching to urothelial cells and facilitating their removal during voiding. This mechanism reduces recurrence rates. .
Fosfomycin, used as a single-dose treatment for uncomplicated UTI, inhibits peptidoglycan synthesis by targeting which enzyme?
Enolpyruvyl transferase (MurA)
DNA gyrase
30S ribosomal subunit
RNA polymerase
Fosfomycin irreversibly inhibits MurA (enolpyruvyl transferase), an enzyme crucial for the first step of peptidoglycan synthesis. This unique mechanism makes it effective against resistant uropathogens. .
Which systemic condition significantly increases the risk of complicated UTIs due to impaired host defenses and bladder dysfunction?
Diabetes mellitus
Osteoarthritis
Rheumatoid arthritis
Hyperthyroidism
Diabetes mellitus impairs immune function and can cause neurogenic bladder dysfunction, both of which increase susceptibility to complicated UTIs and more severe infections. Good glycemic control reduces these risks. .
Vaccine development against UTIs often targets which bacterial structure to prevent colonization?
Lipopolysaccharide O-antigen
Capsular polysaccharide
Type 1 fimbriae (pili)
Flagellar proteins
Type 1 fimbriae (pili) mediate adhesion of uropathogenic E. coli to bladder epithelial cells. Vaccines targeting the FimH adhesin aim to block this critical step in colonization. .

Cheat Sheet

  1. Urinary Tract Anatomy -

    Review the structure of the upper (kidneys, ureters) versus lower (bladder, urethra) urinary tract to understand infection sites. Remember that most infections start in the bladder (cystitis) and can ascend to the kidneys (pyelonephritis) if untreated (source: CDC). Use the mnemonic "KUB-H" (Kidney, Ureter, Bladder - Health check) to recall these segments.

  2. Key UTI Symptoms -

    Memorize the classic signs: dysuria, urinary frequency, urgency, suprapubic discomfort, and possible hematuria (source: Mayo Clinic). A handy mnemonic is the "4 Fs": Frequency, Flank pain/fever, Foul odor, and Full bladder sensation. Recognizing these helps distinguish UTIs from other causes of pelvic pain.

  3. Major Risk Factors -

    Common predisposing factors include female anatomy, sexual activity, condom/spermicidal use, catheterization, menopause, and diabetes (source: NEJM). Recall the "5 Cs" to spot risks: Catheters, Contraceptives, Comorbidities (e.g., diabetes), Cleanliness lapses, and Changes in estrogen. Identifying these aids both prevention and targeted patient education.

  4. Diagnostic Testing -

    Understand dipstick urinalysis for nitrites and leukocyte esterase as rapid screening tools, followed by microscopy and urine culture for confirmation (source: UpToDate). The mnemonic "NITRO" helps: Nitrites, Infection markers, Test rapid, Read culture, Organism ID. Accurate testing distinguishes asymptomatic bacteriuria from true infection.

  5. First-Line Treatments & Prevention -

    Learn first-line antibiotics for uncomplicated UTIs: Nitrofurantoin, Fosfomycin, or TMP-SMX for 3 - 5 days (source: IDSA guidelines). Use the "NFT" mnemonic: Nitrofurantoin, Fosfomycin, TMP-SMX to memorize options. Emphasize hydration, proper voiding habits, and post-coital voiding to reduce recurrence.
