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 ...
Cystic kidney disease refers to a wide range of hereditary, developmental, and acquired conditions [1] and with the inclusion of neoplasms with cystic changes, over 40 classifications and subtypes have been identified. Depending on the disease classification, the presentation may be at birth, or much later into adult life.
Histopathologic types of kidney tumor, with relative incidences and prognoses. Cystic nephroma is seen at bottom right in pie chart. cystic partially differentiated nephroblastoma; cystic standard nephroblastoma (cystic Wilm's tumor) cystic mesoblastic nephroma; cystic renal cell carcinoma; other renal cysts
Ultrasonographic examination can be useful in evaluating questionable asymptomatic kidney tumours and cystic renal lesions if computed tomography imaging is inconclusive. This safe and non-invasive radiologic procedure uses high frequency sound waves to generate an interior image of the body on a computer monitor.
In both male and female children, renal tumors represent 2% to 6% of kidney cancer, with Wilms' tumor [14] being the most common. Sex. The incidence of kidney cancer is two times greater in men than in women, and this is thought to be due to biological differences. Mortality rates typically decrease more rapidly in women compared to men. [12]
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).
In modern English, tumor (non-US spelling: tumour) is used as a synonym for a neoplasm (a solid or fluid-filled cystic lesion that may or may not be formed by an abnormal growth of neoplastic cells) that appears enlarged in size. [12] [13] Some neoplasms do not form a tumor; these include leukemia and most forms of carcinoma in situ.
It is most commonly seen in people with end-stage kidney disease who have a much higher risk of developing acquired cystic kidney disease (ACKD). Affected individuals have small kidneys with several cysts and their risk of renal cell carcinoma is 30 times higher than people without ACKD.
