EBQ:Hematuria in Renal Colic
How accurate is urinalysis for detecting ureteral stones?
The presence or absence of blood on urinalysis cannot be used to reliably determine which patients have ureteral stones.
Urinalysis compared to noncontrast CT (gold standard):
Retrospective chart review of 950 patients who had a formal microscopic urinalysis within 24 hours of undergoing a non-contrast helical CT.
Workup and treatment according to treating physician (retrospective review).
