Glomerulocystic Kidney Disease (GCKD) is a rare condition where cysts form in the kidneys’ filtering units (glomeruli). This can lead to kidney damage and affect how well the kidneys work.
Pathophysiology
- Structure: The kidneys contain tiny filtering units called nephrons, which consist of glomeruli (where blood is filtered) and tubules (where urine is formed). In GCKD, the glomeruli develop cysts, which disrupt this filtering process.
- Blood Supply: The kidneys receive blood from the renal arteries, which supply oxygen and nutrients. The blood then flows back to the heart through the renal veins.
- Nerve Supply: The kidneys have a nerve supply that helps regulate their functions, including blood flow and urine production.
