Medullary Sponge Kidney (MSK) is a rare kidney disorder characterized by cystic dilation of the collecting tubules in one or both kidneys. This leads to a sponge-like appearance of the kidney tissue, which can cause various complications.
Pathophysiology
Structure:
- The kidneys are made up of different parts, including the cortex (outer layer) and medulla (inner layer).
- In MSK, the collecting tubules in the medulla become dilated, creating small cysts. This can affect kidney function.
Blood Supply:
- The kidneys receive blood from the renal arteries, which branch off from the aorta.
- In MSK, the blood supply remains normal, but the structure of the kidney is altered.
Nerve Supply:
- The kidneys are innervated by the autonomic nervous system, which controls involuntary functions.
- The nerve supply does not change in MSK but may be involved in pain sensations related to the condition.
Types of Medullary Sponge Kidney
- Unilateral MSK: Affects one kidney.
- Bilateral MSK: Affects both kidneys.
- Syndromic MSK: Associated with other genetic conditions like von Hippel-Lindau disease or cystic kidney disease.
Causes of Medullary Sponge Kidney
