A rare case of concurrent renal agenesis and Ectopia in a feline system
Abstract
Background: This report describes the first documented case of renal agenesis associated with ectopia of the contralateral kidney in a feline in veterinary medicine. Unilateral renal agenesis is a rare congenital anomaly characterized by the complete absence of one kidney. Renal ectopia, in turn, refers to the anomalous location of the kidney and is a rare condition. The simultaneous occurrence of these anomalies is extremely uncommon.
Case description: A 2-year-old spayed female mixed-breed cat presented with apathy, hyporexia, and vomiting. Laboratory tests revealed azotemia, and imaging tests confirmed the absence of the right kidney and the ectopic position of the left kidney, as well as alterations compatible with chronic kidney disease. Abdominal ultrasonography and excretory urography confirmed the diagnosis.
Conclusion: Coexisting renal agenesis and ectopia are rare conditions in humans, and there are no reports of them in felines. Despite its rarity, the condition is compatible with life, as long as it is diagnosed early and continuously monitored.
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
