title: Encrusted Uretero-pyelitis: Case Report.
abstract: Encrusted uretero-pyelitis is a rare and serious disease, related to the presence of calcifications in the pelvicalyceal system and ureter, associated with chronic urinary tract infection. In most cases, the causal agent of this infection lithiasis is corynebacterium urealyticum. The specific aspect of calcifications on CT scan can help to suggest diagnosis. To avoid a delay in diagnosis (which is frequent), an accurate exploration by the bacteriologist is crucial. The combination of a glycopeptides antibiotherapy and urine acidification has proved its effectiveness, as described in the medical literature. We report the case of a 77-year-old male patient, successfully treated for a bilateral encrusted uretero-pyelitis by local acidification (Thomas's solution) followed by oral acidification (ammonium chloride).
