Revision as of 03:26, 6 May 2012

The kidney is an important organ in the abdomen that does the following:

  • Water balance & blood pressure regulation,
  • Acid-base balance,
  • Removes toxins/cleans the blood, and
  • Produces hormones (e.g. erythropoietin).

Tumours

This is mostly the domain of urology.

This article cover the common renal tumours:

  • [[Renal cell carcinoma].
  • Oncocytoma.
  • Most other tumours... except urothelial tumours are dealt with in the urothelium article.

Pediatric tumours are covered in pediatric kidney tumours.

Medical kidney diseases

This is almost a specialty for itself. Lots of interaction with nephrologists.

Developmental

Horseshoe kidney

General

  • Anatomical variant.
  • Prevalence ~1 in 500.[1]

Gross

  • The inferior poles of the kidneys are joined with one another - have the shape of a horseshoe.

Multicystic renal dysplasia

General

  • Most common cause of abdominal mass in newborns.[2]
  • Subtype of renal dysplasia.[2]
  • May be unilateral or involve only part of a kidney.[3]

Gross

  • Kidney has multiple large cysts.

Microscopic

Features:[3]

  • Cystic spaces.
  • Fibrous stroma.
  • Islands of cartilage.
