Summary
A young alpaca (cria) experienced kidney failure due to congenital defects. Necropsy confirmed right renal agenesis, leading to acute renal failure in the remaining left kidney.
Area of Science:
- Veterinary Medicine
- Comparative Pathology
- Alpaca Health
Background:
- Congenital anomalies in livestock can lead to significant health issues.
- Renal agenesis, the absence of a kidney, is a rare but serious condition.
- Early diagnosis and treatment are crucial for affected animals.
Observation:
- A 4-day-old alpaca cria presented with inappetence, initially responding to treatment.
- The cria relapsed with severe inappetence and azotaemia (elevated nitrogenous waste products in blood).
- Ultrasound revealed no right kidney and perirenal edema around the left kidney.
Findings:
- Diagnosis of right renal agenesis and acute renal failure of the left kidney.
- Necropsy confirmed agenesis of the right kidney, ureter, and renal artery.
- Histopathology of the left kidney showed severe acute tubular degeneration and nephrosis, with the cause undetermined.
Implications:
- This case highlights the challenges in diagnosing and managing congenital renal defects in young alpacas.
- Understanding renal agenesis is vital for veterinary practitioners dealing with similar presentations.
- Further research may be needed to identify potential causes or genetic factors contributing to renal agenesis in camelids.
