Clinical Question
How accurate is urinalysis for detecting ureteral stones?
Conclusion
The presence or absence of blood on urinalysis cannot be used to reliably determine which patients have ureteral stones.
Major Points
Urinalysis compared to noncontrast CT (gold standard):
Sensitivity 84%
Specificity 48%
Study Design
Retrospective chart review of 950 patients who had a formal microscopic urinalysis within 24 hours of undergoing a non-contrast helical CT.
