An 11-year-old female mixed-breed dog admitted due to anorexia and vomiting. Radiography showed 7.6-mm uroliths in the right proximal ureter and an enlarged kidney. Type 1 emphysematous pyelonephritis (EPN) was diagnosed using computed tomography (CT) in the awake dog. Right ureteronephrectomy was performed, and Escherichia coli was isolated. The stone was consisted of 80% calcium oxalate. At the 6-month follow-up, no complications were observed. This is the first report of EPN caused by calcium oxalate in a dog. In addition, we suggest performing CT in weak animals to diagnose EPN without anesthesia.

편측 수뇨관증과 수신증으로 내원한 개에서 편측성 신요관절제술을 시행하였다. 개복 시 유착조직이 신장의 안쪽 면에서부터 복대동맥 위까지 형성되어 있었으며, 등쪽안쪽면과 복대동맥 사이에 유착조직이 형성되어 있었다. 또한 좌측 난소가 신장의 꼬리쪽 극에 유착되어 있었다. 유착조직의 형성으로 인해 신장 동맥과 정맥을 구별하여 결찰하는 것이 불가능 하였기 때문에 신장의 안쪽면 두 곳에서 집단결찰을 시행한 후 유착조직을 신장의 안쪽면에서 분리하였다. 신장의 등쪽안쪽면과 복대동맥사이에 형성된 유착조직으로부터 신장을 분리하기 위해 유착조직을 절개해 나갈때 신장동맥의 절제로 인한 출혈이 발생하였다. 출혈의 원인은 복대동맥에서 분지되어 나온 신장동맥부위가 신장의 등쪽안쪽면과 유착이 되어있었기 때문에 신장의 안쪽면에 적용한 집단결찰에 신장동맥이 포함되지 못하였던 것으로 생각된다. 발생된 출혈은 절제된 신장동맥의 이중결찰과 전기소락기를 이용하여 멈추게 하였다. 본 증례를 통해, 신장이 주변복강 장기와 심하게 유착되어 신장 동, 정맥을 구별하여 결찰하기 힘든 경우 집단 결찰법을 선택할 수 있으며, 집단결찰법은 해부학적으로 신장 동, 정맥이 신장으로 들어가는 안쪽면 뿐만 아니라 유착이 형성된 신장의 모든 면에 선택적으로 적용되어야 한다고 생각한다.

An 11-year-old, 4.3 kg, mixed breed, intact female dog exhibiting vomiting and a reduced appetite was presented. On physical examination, palpation of the right kidney elicited discomfort. Blood analysis revealed leukocytosis with neutrophilia, and elevation of alkaline phosphatase and blood urea nitrogen. Escherichia coli was detected in urine culture, whereas urine analysis showed absence of glucose. Radiography and ultrasonography suggested that there was gas in the right renal parenchyma, and computed tomography was performed while the dog was awake to investigate the suspected gas in the right kidney. After unilateral ureteronephrectomy, a histological diagnosis of right emphysematous pyelonephritis (EPN) was made. EPN refers to a severe necrotizing infection of the renal parenchyma with gas accumulation in the tissue. It is rare in both human and veterinary medicine, and almost all EPN patients have uncontrolled diabetes mellitus. This case report describes the imaging-based diagnosis of a rare occurrence of unilateral EPN in a non-diabetic dog.

Three dogs that had a history of abdominal distension were referred to the hospital. All were female with unilateral involvement. History and clinical signs were nonspecific. Abdominal radiographs demonstrated that the abdomen of all cases was filled with large masses. At laparotomy, all masses were kidney tumors with invasion around tissue. The tumors were soft, irregular, creamish and confined within the capsule. One case had liver metastasis. Another case was found to have adrenal gland metastasis. One case had caudal vena cava invasion. A ureteronephrectomy was performed unilaterally in all cases. In the microscopic appearances, all the tumors had malignant features with nuclear pleomorphism and amount of necrosis. Three cases were diagnosed as renal carcinomas.
