What is pyelonephritis in children? How common is it?
Pyelonephritis in children (Pyelonephritis) or kidney infection is a condition cause by a bacterial infection of the kidney or renal pelvis. Most commonly, it is the bacteria E. coli (Escherichia coli) found in the rectum and large intestine. The bacteria enter the urinary tract through the urethra and travel up the ureters to the kidneys, causing pyelonephritis. This condition occurs in about 3% of infants, and usually occurs in children under 2 years of age because their urinary tract systems are not yet fully developed and are at risk of vesicoureteral reflux (VUR), which is a major factor in infection. It can also occur in children with congenital abnormalities of the kidneys or ureters.
During infancy, boys are at higher risk of developing pyelonephritis from a urinary tract infection (UTI).
Than girls because boys are more likely to have congenital urinary tract abnormalities, such as vesicoureteral reflux or เล่นบาคาร่า UFABET เว็บตรง ค่าคอมสูง urethral atresia. However, as children grow older, girls are at higher risk than boys because their urethra is closer to the anus, making them more susceptible to bacterial contamination.
Pyelonephritis can cause permanent kidney damage, especially in cases of severe or recurrent infections, which can affect growth and lead to kidney fibrosis, chronic kidney disease, or other complications such as high blood pressure.
Factors and causes of pyelonephritis in children
The occurrence of pyelonephritis in children. Can caused by the following factors and causes
- Urinary tract infections (UTIs) that spread from the bladder to the kidneys.
- Vesicoureteral Reflux (VUR) is cause by urine flowing backward from the bladder into the ureter and up into the renal pelvis. This condition often causes repeated infections. Because it is cause by abnormalities of the ureter. The distal end of the ureter where it connects to the bladder is often abnormally short or in the wrong position. In some cases. It can caused by obstruction of the ureter, such as kidney stones or congenital abnormalities. Including abnormal bladder function that causes high pressure, causing urine to flow back up into the renal pelvis. Vesicoureteral Reflux can also cause by phimosis in boys and labial adhesion in girls.
In addition, poor hygiene , such as improper cleaning that allows bacteria to build up around the genitals or the use of a urinary catheter, can also allow bacteria to spread into the urinary tract, as can dehydration, which causes concentrated urine. Which is an environment conducive to bacterial growth.
