Symptoms such as fever or chills or nausea suggest the presence of a more serious infection, such as a kidney infection, and should receive immediate medical attention. Pregnant women may not have any symptoms of infection, so their urine should be checked during their regular prenatal doctor visits.
Urethritis is inflammation of the urethra. That's the tube that carries urine from the bladder to outside the body.
