Flashcards in Pharmacology: UTI Deck (130)
How many cases of symptomatic UTI are seen each year?
What is the lifetime risk of having at least 1 UTI among women?
Higher than 50%
In very young children, do boys or girls get more UTIs?
Very young boys--> They have a higher frequency of urethral malformations
In older kids, who gets more UTIs?
In adults, who gets more UTIs?
Why do women get more UTIs?
They have a short urethra, so bacteria has easier access to the urinary tract
What category of women get UTIs most commonly?
In people over 50, who gets more UTIs?
It is equal between elderly men and elderly women
What are the 3 types of UTI with associated % of occurrence?
1. Cystitis (90%)
2. Pyelonephritis (10%)
Which types of UTI are symptomatic?
Cystitis and pyelonephritis
What is the description of asymptomatic UTI?
Bacteria in urine, no symptoms
Where does cystitis affect?
Bladder and lower UT
Where does pyelonephritis affect?
Kidney and upper UT
What categorizes sporadic recurrence and what is the % of affect?
Under or equal to 1 UTI in 6 months and under or equal to 2 UTI in a year
What categorizes recurrent UTI and what is the % of affect?
Over or equal to 2 UTI in 6 months and over or equal to 3 UTI in a year
What are the 2 subcategories under recurrent UTI and describe
1. Relapse: No time between infection and usually with same strain of bacteria
2. Reinfection: Patient is cured from bacteria in urine and there is a period of time with no bacteria...if it comes back, it is usually a different strain
What % of UTI are considered complicated?
What 4 features are associated with complicated UTI?
1. Structural abnormalities, like a urinary tract obstruction (calculi, catheters, prostatic hypertrophy)
2. Metabolic/hormonal abnormalities (diabetes and pregnancy)
3. Impaired host responses (renal transplants) and AIDS
4. Unusual pathogens (yeast or hospital-acquired infection)
What is the consequence of complicating factors?
Longer therapy and a more detailed workup (no guidelines just recommendations.... make sure to treat complication 1st before bacterial infections)
What are symptoms of cystitis?
Frequent voiding, burning during and after voiding, suprapubic pain, hematuria and/or cloudy urine
What are symptoms of pyelonephritis?
FEVER, flank pain, chills, with or without cystitis symptoms
What can cystitis symptoms mimic?
Urethritis from STDs
What can be done to differentiate between cystitis and urethritis?
Urinalysis and urine culture
What is seen in urinalysis and culture for cystitis?
Pyuria, most have bacteriuria, half have hematuria
-See organisms on culture
What is is seen in urinalysis and culture for urethritis?
Pyuria, no bacteruria, no hematuria
-No bacteria on culture
What can pyelonephritis be mixed up with?
How do you differentiate from pyelonephritis and renal stones?
Similar pain location for both... but pyelonephritis has FEVER
What is seen on urine analysis for diagnosis of UTI?
Pyuria with bacteruria
What blood tests need to be done with pyelonephritis?
