4ferrets

Synonym(s): Kidney cysts, Polycystic disease


Introduction

  • Cause: congenital or secondary to other kidney diseases.
  • Signs: usually asymptomatic.
  • Diagnosis: radiography, ultrasonography, palpation, urinalysis.
  • Treatment: surgical drainage of cysts, resection of renal caspule.
  • Cysts may develop in the kidney parenchyma.
Clinical tip
Question: Can ultrasound help diagnose renal cysts in ferrets?
Answer: Yes; renal cysts are commonly found incidentally, either in necropsies or during physical examinations, but cysts can easily be identified on renal ultrasonography.

Pathogenesis

Etiology

  • Some are present at birth indicating congenital in formation.
  • Cysts may be an incidental finding on ultrasound, some may become extremely large but generally expand rather than compress kidney tissue.
  • Rarely is there any kidney disease indicated by BUN and creatinine (normal values).
  • They may be classified as either perinephric pseudocysts or polycystic kidneys.
  • Kidney cysts may be secondary to other kindney diseases, particularly chronic end-stage kidney disease.
  • Cysts may be single or multiple, and can be present on one or both kidneys.

Predisposing factors

General

  • Other kidney diseases.

Epidemiology

  • Approximately 10-15% ferrets have renal cysts, but some reports have noted up to 69% prevalence when using histology.
