Other tests may be ordered if your doctor thinks that there is some other problem causing the urinary tract infection, such as a kidney stone or a condition called reflux, in which the urine backs up from the bladder toward the kidneys, or if there is a history of recurrent infections.
Most urinary tract infections (UTIs) involve only the bladder and urethra (the lower urinary system). Pyelonephritis results when a UTI progresses to involve the upper urinary system (the kidneys and ureters).
The kidneys filter the blood to produce urine. Two tubes called the ureters carry urine from the kidneys down to the bladder. Urine travels from the bladder out of the body through the urethra.

What Are the Treatments for a Urinary Tract Infection?
Most cases of simple acute cystitis -- a single episode of a bladder infection -- in young women can be treated with a three- to seven-day course of an antibiotic. If symptoms come back, additional tests might be done to rule out other problems.
Pregnant women, patients with diabetes, patients with kidney stones or other obstructions to the flow of urine, and people who have had symptoms for longer than a week, should all be given a 5- to 14-day course of antibiotics. When infection has spread to the kidneys, then treatment should continue to 10-14 days. In men with prostatitis, the antibiotics should be given for several weeks.
You should also drink lots of water to help wash out the bacteria from the urinary system.
To confirm that the treatment was successful, your doctor may repeat urine cultures one to two weeks after you finish the antibiotic. Pregnant women who have been treated for an infection should have monthly urine tests performed until their baby is delivered.
