How Is a Urinary Tract Infection Diagnosed?

How is a urinary tract infection diagnosed?

In addition to a complete medical history and physical examination, diagnostic tests and procedures may include the following:

• Urinalysis-laboratory examination of urine for various cells and chemicals, such as red blood cells, white blood cells, infection, or excessive protein
• Intravenous pyelogram (IVP)-a series of x-rays of the kidney, ureter, and bladder — aided by the injection of a contrast dye into the vein — to detect tumors, abnormalities, kidney stones, or any obstructions; it is also used to assess renal blood flow
• Cystoscopy(also called cystourethroscopy)-an examination in which a scope, a flexible tube, and a viewing device are inserted through the urethra to examine the bladder and urinary tract for structural abnormalities or obstructions, such as tumors or stones
• Renal ultrasound-a noninvasive test in which a transducer is passed over the kidney; the transducer produces sound waves, which bounce off of the kidney, transmitting a picture of the organ to a video screen; the test is used to determine the size and shape of the kidney, and to detect a mass, kidney stone, cyst, or other obstruction or abnormalities
