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.
