Abdominal ultrasound examinations of 20 dogs with confirmed leptospirosis were reviewed retrospectively for renal abnormalities. Three dogs had a normal ultrasound examination. The remaining 17 dogs had sonographic abnormalities of the kidneys. These abnormalities, seen either alone 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 been seen in dogs with leptospirosis and may therefore be a specific sonographic sign for this disease.
对20只确诊钩端螺旋体病的犬进行腹部超声检查，回顾性分析肾脏异常情况。3只犬超声检查正常。其余17只犬肾脏有超声异常。这些异常单独或合并出现，包括肾肿大（n = 10）、肾盂扩张（n = 9）、皮质回声增强（n = 15）、肾周积液（n = 5）和髓质回声增强带（n = 6）。在我们机构，髓质回声增强带仅在钩端螺旋体病犬中见到，因此可能是该病的一个特异性超声征象。
