Podcast:


Introduction

  • Cause: familial disease in certain breeds.
  • Signs: usually asymptomatic, occasionally present with chronic renal failure Kidney: chronic kidney disease.
  • Diagnosis: radiography, ultrasonography.
  • Treatment: none.
  • Prognosis: guarded if chronic renal failure, animal may be normal.

Pathogenesis

Etiology

  • Congenital.
  • Familial.

Pathophysiology

Agenesis

  • Unilateral agenesis is usually asymptomatic (unless other kidney is damaged).
  • More commonly affects right kidney than left.
  • In female ipsilateral uterine horn is absent but ovary normal.
    If one uterine horn absent at time of spay check for presence of kidney.

Fusion

  • Isolated reports but very rare.

Ectopia

  • Isolated case reports of congenital ectopia, frequently bilateral.
  • Occasionally occurs as a result of trauma Kidney: trauma.

Congenital polycystic disease

Primary familial nephropathy

  • Abnormal development of renal parenchyma  →  immature glomeruli and other inappropriate structures  →  renal failure.
  • ?Not reported in cats.
  • Familial amyloidosis Amyloidosis in Abyssinian cats Abyssinian. Also described in Siamese Siamese and Oriental cats Oriental shorthair.
