Crossed renal ectopia with fusion in a female feline: case report

ABSTRACT A 3 year old female feline of mixed breed was sent to the diagnostic imaging sector under suspicion of bleeding due to ovariohysterectomy. An abdominal ultrasonography was performed to confirm the initial suspicion. However, no signs of bleeding were found, instead it was observed that the left renal silhouette had two pelvises and was elongated and larger than normal. The right kidney was not found. Excretory urography was requested to evaluate the condition of the ureters. The final diagnosis was crossed renal ectopia with fusion in an asymptomatic cat with no changes in renal function.

【摘要】一只3岁雌性混血家猫，因疑似卵巢子宫摘除术（ovariohysterectomy）后出血被转诊至诊断影像学科室。为验证初始怀疑，临床对其实施腹部超声检查（abdominal ultrasonography）。检查未发现出血相关征象，但观察到左侧肾脏轮廓存在双肾盂，且形态拉长、体积超出正常范围；未探及右侧肾脏。为评估输尿管状况，后续安排了排泄性尿路造影（excretory urography）检查。最终诊断为：该无症状猫咪罹患交叉性肾异位（crossed renal ectopia）并融合，且肾功能无异常改变。
