SONOGRAPHIC RENAL FINDINGS IN 20 DOGS WITH LEPTOSPIROSIS

Abdominal ultrasound examinations of 20 dogs with confirmed leptospiro sis were reviewed retrospectively for renal abnormalities, Three dogs had a normal ultrasound examination. The remaining 17 dogs had sonogra phic abnormalities of the kidneys. These abnormalities, seen either al one or in combination, included renalmegaly (n = 10), pyelectasia (n = 9), increased cortical echogenicity (n = 15), perinephric effusion (n = 5), and a medullary band of increased echogenicity (n = 6), At our institution, the medullary band of increased echogenicity has only bee n seen in dogs with leptospirosis and may therefore be a specific sono graphic sign for this disease.
