Answer

Fever, chills, nausea, and vomiting are the most common signs and symptoms. Patients with pyelonephritis often attempt to avoid movement, while those with renal colic often move persistently in an attempt to find a comfortable position. 

Flank and costovertebral angle tenderness are present and can be confirmed with percussion. Other signs of urinary tract infection, such as suprapubic pain, dysuria, frequency, and urgency, are often present. Fever, leukocytosis, and pyuria are typical findings.
