[Parietal calcifications of the kidney pelvis in Corynebacterium urealyticum urinary infection].

Linear renal pelvis calcifications in a native kidney due to Corynebacterium urealyticum are described. These micro-organisms have an opportunistic behaviour and can be responsible for nosocomial urinary tract infection. Alkaline incrusted cystitis with linear vesical calcifications are considered as the most typical pattern. Renal pelvis may also be concerned, with parietal calcifications.
