Difference in urinary tract, kidney, and bladder infections? or symptoms? how long does it take to get urine test results? treatment for 2 year old?

Not a simple answer: Typically with a bladder infection you get more local symptoms like dysuria, hematuria, sensation of needing to go the bathroom often. With an upper urinary tract infection (kidneys, tract) you may get more systemic symptoms like fever, abd pain, vomiting. Urinalysis is a quick test (seconds), a urine culture takes 1-2 days. Abx choice is the same, may need IV if really sick and vomiting.

UTi: There is usually no difference between bladder and kidney infection other than fever. Kidney infection tend to have fevers. Other symptoms of kidney infection is vomiting, back pain, more sick-looking. Bladder infections tend to have frequency, pain on voiding and urgency. Results of urinalysis is usually available immediately at the pediatrician's office.
