title: [Atypical forms of primary acute pyelonephritis].
abstract: In acute "primary" pyelonephritis (APP), kidney infection occurs despite normal urinary tract morphology. Typical features of APP are spiking fever and chills, loin pain, pyuria, bacteriuria, isolation of uropathogenic strains of E. coli, and specific renal CT scan images. APP may be atypical when lacking pain, or fever, or when urine cultures are negative, or when urinary bacteria do not exhibit characters of uropathogenicity, or when CT scan examination is negative. Such atypical features entail loss of time in diagnosis, and thereby delayed treatment and increased risk of cortical scar formation. However, they are virtually never observed simultaneously in a given patient.
