UTI Stratification: Distinguishes between simple and complicated UTIs to guide antibiotic selection and duration (typically 3-5 vs 7-14 days).

Uncomplicated UTI
Standard therapy likely sufficient. No high-risk host or structural factors detected.

Section 1
When to Use
When to Use
Use when evaluating a patient with symptoms of a urinary tract infection to determine if host factors necessitate an escalated workup, imaging, or longer antibiotic duration.
Core Definitions
["Uncomplicated UTI: Infection in a healthy, non-pregnant woman with a normal urinary tract.","Complicated UTI: Infection in a patient with factors that increase the risk of treatment failure or serious complications."]
Section 2
Risk Factors
Complicating Host Factors
["Male gender (historically considered complicated, though some simple cystitis in men exists)","Pregnancy","Elderly patients","Diabetes mellitus (especially if poorly controlled)","Immunosuppression","Kidney transplant"]
Complicated UTIs typically require a urine culture and sensitivity. Imaging (CT/US) should be considered if structural abnormalities or stones are suspected.
Regimen Principles
Uncomplicated: Short-term therapy (3–5 days). Complicated: Extended therapy (7–14 days) and broader empiric coverage if pyelonephritis or multi-drug resistance is suspected.
Section 4
Evidence
Guidelines
Aligned with IDSA and EAU (European Association of Urology) guidelines on the management of urological infections.
