Etiology of renal pyelonephritis in children

Common pathogens are Escherichia coli, Escherichia coli, Salmonella, followed by Staphylococcus, Streptococcus, Streptococcus pneumoniae, Proteus, Pseudomonas aeruginosa, Aerobacter aerogenes and Alcaligenes. For chronic pyelonephritis, sometimes mixed with a variety of mixed bacteria.

Route of infection:

(2) bloody infection: upper respiratory tract infection, skin impetigo, sepsis and other diseases, bacteria by the blood system infection, pathogens are mostly Streptococcus or Staphylococcus aureus.


(3) through the intestinal and kidney between the lymphatic spread.

How to diagnose children with pyelonephritis

Routine clinical testing means more difficult to distinguish between the two clear, foreign researchers collected 100 first suspected urinary tract infection and hospitalized children with blood samples, including serum pre-calcitonin (PCT) and CRP, erythrocyte The presence or absence of renal parenchymal injury was determined by 99mTc - DMSA scans.
