Renal dysplasia is a type of familial kidney disease characterized by abnormal cellular differentiation of kidney tissue. Dogs and cats with kidney disease caused by these diseases have the typical symptoms of kidney failure, including weight loss, loss of appetite, depression, and increased water consumption and urination.

The tumor parenchyma, of a solid tumour, is one of the two distinct compartments in a solid tumour. The parenchyma is made up of neoplastic cells. The other compartment is the stroma induced by the neoplastic cells, needed for nutritional support and waste removal. In many types of tumour, clusters of parenchymal cells are separated by a basal ...
The RENAL Nephrometry Scoring System is used to measure the complexity of kidney tumors for determining whether a renal mass is appropriate for partial or radical nephrectomy, and is estimated by CT scan as follows: [7] The nephrometery score takes into account the size of the tumor (Radius), how much of the tumor is inside or outside of the ...
It may cause acute kidney injury. It is now more commonly used to describe diffuse, fine, renal parenchymal calcification in radiology. [2] It is caused by multiple different conditions and is determined by progressive kidney dysfunction. These outlines eventually come together to form a dense mass. [3]
[2] [3] The high number of affected dogs at the Greenetrack Racing Park, Alabama, led to the initial pseudonyms of Greenetrack Disease and Alabama Rot. [4] The initial symptoms are skin lesions on the legs, chest and abdomen followed by renal involvement. [2] [3] In November 2012 the first cases were suspected in the UK. [5]
For small exophytic lesions that do not extensively involve the major vessels or urinary collecting system, a partial nephrectomy (also referred to as "nephron sparing surgery") can be performed. This may involve temporarily stopping blood flow to the kidney while the mass is removed as well as renal cooling with an ice slush.
Gross appearance of a renal oncocytoma (left of image) and a slice of a normal kidney (right of image). Note the rounded contour, the mahogany colour and the central scar. In gross appearance, the tumors are tan or mahogany brown, well circumscribed and contain a central scar. They may achieve a large size (up to 12 cm in diameter).
Papillary renal cell carcinoma (PRCC) is a malignant, heterogeneous tumor originating from renal tubular epithelial cells of the kidney, which comprises approximately 10-15% of all kidney neoplasms. [1] Based on its morphological features, PRCC can be classified into two main subtypes, which are type 1 and type 2 (eosinophilic). [2]
