Background: The kidneys are a pair of organs that maintain homeostasis, and perform hormonal and excretory functions; the functional unit of the kidney is the nephron. Approximately 2% of cats are born with some structural or functional anomaly, which occurs during fetal development. Unilateral renal agenesis is a rare congenital anomaly in felines, where the cat has only one kidney. This can lead to a series of dysfunctions, with clinical signs, especially when the contralateral organ does not adequately compensate, since there is more than one concomitant congenital disease like kidney dysplasia, which is the abnormal formation of the kidney structures. This study aimed to report the case of a kitten diagnosed with unilateral renal agenesis; the clinical signs, diagnosis, and treatment. Case: A 2-month-old mixed breed female kitten, weighing 0.5 kg, was attended in a veterinary clinic with emesis, hyporexia, hypodipsia, normuria, and diarrhea. Upon physical examination, dehydration, hyperthermia, and renomegaly by abdominal palpation were observed. Complementary examinations such as serum urea and creatinine estimation, abdominal ultrasound, and excretory urography, were requested, and the results include hemoglobin (9 g/dL), mean corpuscular volume (26%), normocytic normochromic anemia, urea (312 mg/dL), and creatinine (3.5 mg/dL). The abdominal ultrasound showed renomegaly on the left kidney and the absence of the right kidney. The above results and excretory urography help to confirm the diagnosis of unilateral renal agenesis and suggested renal dysplasia. The patient was hospitalized to stabilize her condition. The treatment is symptomatic and supportive and aims to increase the patients quality of life. Treatment with metoclopramide, erythropoietin, fluid therapy with ringers lactate solution, and renal therapeutic feed was prescribed. After 4 days of hospitalization and treatment, the serum creatinine was within normal...(AU)
