Plain-English summary
A 3-month-old kitten weighing about 5.8 pounds was taken to the vet because it was vomiting, having diarrhea, not eating, and seemed very tired. Tests showed that the kitten had high levels of waste products in its blood, indicating kidney problems, and imaging revealed that both kidneys were swollen and there were blockages in the ureters, which are tubes that carry urine from the kidneys to the bladder. The kitten had surgery to bypass the blocked ureter on the left side, remove the right kidney, and take out the affected parts of both ureters. After the surgery, the swelling in the left kidney improved, and the kidney function was almost back to normal. This case is notable because it successfully treated a rare condition in a kitten using advanced imaging techniques.
Abstract
A 3-month-old cat weighing 2.62 kg was brought to the VIP Animal Medical Center with vomiting, diarrhea, anorexia, and depression. Laboratory findings confirmed azotemia with elevated blood urea nitrogen (BUN) (168.9 mg/dl) and creatinine (5.9 mg/dl) and symmetric dimethylarginine (SDMA) (86 μg/dl). Abdominal radiography revealed bilateral renomegaly. Ultrasonography revealed bilateral hydronephrosis and left partial and right complete ureteral obstructions with bilateral focal irregular and circumferential thickenings at ureters. Reduction of bilateral renal function was confirmed through excretory urography on computed tomography. The cat underwent subcutaneous ureteral bypass surgery on the left kidney, right nephrectomy, and bilateral ureterectomy. Histopathology of bilateral ureteral irregular and circumferential thickening revealed bilateral atypical papillary transitional mucosal hyperplasia. Three days after surgery, the left hydronephrosis resolved, and azotemia was almost resolved. This is the first report of successful management of ureteral stenosis with congenital papillary transitional mucosal hyperplasia in a kitten using multimodality imaging.
