Three Part Question

In a [ patient presenting with symptoms suggestive of renal colic] is the [absence of hematuria] [sensitive to role out this diagnosis]?

Clinical Scenario

You are called to the emergency department to see a 35 years old man who presented with severe left loin to groin pain and vomitting. On examination you find him rolling in the bed, tachycardic and has a left renal angle tenderness. You control his pain and decide to run a urine test to confirm the diagnosis of renal colic. The urine dipstick comes back as normal, and leaves you with this question: How sensitive is the lack of hematuria in rule out the diagnosis of acute renal colic?
