Mid-term Flashcards
1
Q
What classifies an uncomplicated UTI?
A
An infection which occurs in healthy, immunocompetent, non-pregnant women (can occur in men too) with no significant UTI history or any urological structural abnormalities
Symptoms are mild-moderate
2
Q
What classifies a complicated UTI

18
Q
What follow up is required with UTIs
A
- Acute simple cystitis and symptoms resolve on antimicrobials: no F/U urine cultures
- Hematuria on initial presentation: urinalysis several weeks s/p antimicrobial therapy to evaluate for persistent hematuria.
-
Continued symptoms after 48 to 72 hours of empiric antimicrobial therapy OR recurrent symptoms within a few weeks of treatment: additional evaluation for other potential conditions that may be causing those symptoms and for factors that might be compromising clinical response.
- Urine culture and empiric treatment with another abx
- Tailor abx to the susceptibility profile of causative organism
- Persistent symptoms with appropriate antimicrobial therapy: urologic assessment and radiographic imaging (CT) evaluate for anatomic abnormalities that would interfere with response to antimicrobial treatment.
