A urinary tract infection, or UTI, is infection anywhere within the urinary system. The urinary system includes two kidneys, two ureters, the bladder and the urethra. Generally, urinary tract infections involve the lower section of the urinary system, the urethra and the bladder, but if left untreated, infection of the kidneys occurs. Quick treatment of all urinary tract infections is essential to prevent the spread of the infection.
UTI Signs
Signs of a urinary tract include the results of a urine sample. Evidence of an active infection appears as an increased amount of white blood cells, bacteria, blood and pus in the urine. The urine sample may contain one or several of the indicators of an infection. The urine appears dark-colored, cloudy and smells strong. Individuals with a urinary tract infection make frequent trips to urinate but produce little urine each time. Fever and fatigue may accompany the infection, especially for kidney infections. Nausea and vomiting may also occur in kidney infections.
UTI Symptoms
Urinary tract infections cause pain. If the kidneys are infected, the pain is in the back and side. If the bladder or urethra contains the infection, the pain is in the pelvis. Painful burning pain increases when urinating. Pressure in the pelvic area accompanies the pain and burning feelings. Feelings of nausea, fatigue, shakiness and an overall feeling of weakness are common symptoms for urinary tract infections.
Signs and Symptoms in Children
Children will exhibit the same signs and symptoms as adults but are sometimes unable to verbalize the feelings. Increased irritability with inconsolable crying and a decreased appetite are signs of a urinary tract infection in infants and young children. Babies may stop gaining weight because of the decrease in eating. In addition to these symptoms, older children may experience urinary accidents, including bed-wetting. Some children may complain of a stomachache instead of pelvic pain. Because of a short urethra, girls get urinary tract infections more commonly than boys do. Infant girls are especially at risk because of wearing diapers. Older children who no longer need help in the bathroom may not mention symptoms until the infection spreads and worsens. Because of the location of the infection, children may feel embarrassed to talk about their pain. Fast treatment of a lower urinary tract infection is important to prevent the spread to the kidneys. Children are at risk for permanent kidney failure from infections.
