Authors draw attention to unusual forms of tubulointerstitial nephritis and infections of urinary tract because most of them need a particular approach as far as diagnosis and therapy is concerned. They emphasize a different approach to asymptomatic bacteriuria depending on the basic disease of the patient. They pay attention to clinical picture differences in small children up to the age of 5 years, particularly in small babies and newborns whose clinical picture looks like a CNS disease or a disease of GIT. A special approach is needed in infections of pregnant adolescents. Diagnosis of renal and perinephritic abscess is difficult, rarely xanthogranulomatic pyelonephritis or malacoplakia is considered.
