| embryoma of the kidney | <oncology, tumour> Wilm's tumour or nephroblastoma, is a cancerous tumour of the kidney in children. Wilm's is the most common tumour of the kidney and the most common intra-abdominal tumour in children. The exact cause is unknown, but probably develops in foetal tissue due to an underlying genetic factor. Like retinoblastoma, both sporadic and inherited forms occur. Believed to be caused by development of homozygosity for a deletion of the tip of the short arm of chromosome 11, which is presumed to contain a tumour suppressor gene.

| kidney | <anatomy> Two glands situated in the upper posterior abdominal cavity, one on either side of the vertebral column. The kidneys are shaped like two large beans, and act as a filter. The kidney function is to filter the blood and control the level of some chemicals in the blood such as hydrogen, sodium, potassium, and phosphate and they eliminate waste in the form of urine.

| kidney calculi | Calculi occurring in the kidney. Calculi too large to pass spontaneously range in size from 1 cm to the staghorn stones that occupy the renal pelvis and calyces. Bilateral renal calculi cause additional problems, with infection a common occurrence. (12 Dec 1998) |
| kidney calices | Recesses of the kidney pelvis which divides into two wide, cup-shaped major renal calices, with each major calix subdivided into 7 to 14 minor calices. Urine empties into a minor calix from collecting tubules, then passes through the major calix, renal pelvis, and ureter to enter the urinary bladder. (12 Dec 1998) |
