Pyelonephritis in children: causes, symptoms, treatment

Pyelonephritis in children is common. Children most susceptible to this disease are up to the age of five. At the same time, girls suffer from pyelonephritis several times more often than boys. This is due to the fact that the urethra, along which the infection progresses, is much wider and shorter than that of boys.

Pyelonephritis is an inflammatory disease in which the tubular system of the kidney, the renal pelvis, and the parenchyma are affected. Pyelonephritis can occur in three forms - acute, chronic, chronic with exacerbation.

Apparently, with pyelonephritis, the kidneys, that is, the vital organs, on whose shoulders the body cleanses from harmful substances by means of excretion and excretion of urine, suffer. In addition, the kidneys are responsible for the normalization of the water-salt balance, the development of substances necessary for the body to maintain life. If the kidneys are disturbed, other vital organs (lungs, heart, brain) can not function normally.

Why does pyelonephritis develop in children?



The fact that the child's urine does not contain antibacterial substances, in contrast to the urine of an adult. Moreover, in children, in connection with the physiological peculiarity of the organism, with urination, the bladder is not fully emptied.

Everyone knows that the children's body is not characterized by a high ability to resist infection.

One of the main causes of pyelonephritis is caries, tonsillitis. In some cases, pyelonephritis develops in children during intrauterine development. The statistics says that half of the newborns who were in the intensive care unit have kidney lesions. It is possible that hypoxia is one of the factors conducive to the development of the disease.

Infection in the intestines often provokes the development of the inflammatory process, which begins in the genital area, moves along the urethra, penetrating the bladder, and then into the renal pelvis and kidney.
