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
Main article: Kidney 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
Main article: Medical kidney diseases
This is almost a specialty for itself. Lots of interaction with nephrologists. Cystic renal disease is dealt with in a separate article called cystic kidney diseases.
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
- Abbreviated MRD.
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.

Renal medullary dysplasia
General
- Associated with:
- Beckwith-Wiedemann syndrome.[4]
- Placental insufficiency.[5]
Microscopic
Features:[4]
- Widely spaced tubules in the medulla of the kidney.
