| renal cancer | <radiology> About 8300 adults die each year from kidney cancer. An estimated 18100 new cases are diagnosed each year, comprising 2% of all cancers. The average age at diagnosis is 55-60 years., adenocarcinoma (hypernephroma), 80% of renal carcinoma, 66% male, associated with smoking, transitional cell or squamous carcinoma, 15% of renal carcinoma, 50% male, associated with calculous disease Excretory urography may reveal the primary lesion, the degree of local extension and evidence of compression or deviation of the ureter.

| renal capsule | The fibrous connective tissue that surrounds each kidney. (12 Dec 1998) |
| renal carcinosarcoma | <tumour> Obsolete term for Wilms' tumour. (05 Mar 2000) |
| renal cast | Any type of cast formed in a renal tubule, and found in the urine consisting of various materials, e.g., albumin, cells, blood. Synonym: tube cast. (05 Mar 2000) |
| renal cell cancer | Cancer that develops in the lining of the renal tubules, which filter the blood and produce urine. Also called renal cell carcinoma. (12 Dec 1998) |
| renal cell carcinoma | <oncology, tumour> The most common form of kidney cancer which occurs when the cells lining the renal tubule undergo cancerous changes. There are approximately 18,000 new cases of renal cell carcinoma (hypernephroma) per year in the U.S. With about 8,000 deaths annually. Smoking is considered a major risk factor. Kidney dialysis patients are at increased risk for the development of hypernephroma. Family history for renal cell carcinoma is also considered a risk factor. Symptoms include haematuria, flank pain, abdominal pain, back pain, weight loss and abdominal swelling. (27 Sep 1997) |
| renal circulation | The circulation of the blood through the vessels of the kidney. (12 Dec 1998) |
| renal colic | Severe colicky pain caused by the impaction or passage of a calculus in the ureter or renal pelvis. (05 Mar 2000) |
| renal collar | In the embryo, a ring of veins around the aorta below the origin of the superior mesenteric artery. (05 Mar 2000) |
| renal columns | The prolongations of cortical substance separating the pyramids of the kidney. Synonym: columnae renales, Bertin's columns. (05 Mar 2000) |
| renal corpuscle | The tuft of glomerular capillaries and the capsula glomeruli that encloses it. Synonym: corpusculum renis, malpighian corpuscles. (05 Mar 2000) |
| renal cortex | The part of the kidney consisting of renal lobules in the outer zone beneath the capsule and also the lobules of the renal columns that are extensions inward between the pyramids; contains the renal corpuscles and the proximal and distal convoluted tubules. Synonym: cortex renis. (05 Mar 2000) |
| renal diabetes | The recurring or persistent excretion of glucose in the urine, in association with blood glucose levels that are in the normal range; results from the failure of proximal renal tubules to reabsorb glucose at a normal rate from the glomerular filtrate (low renal threshold); defect in the glucose carrier in the nephron. Synonym: diabetes innocens, normoglycaemic glycosuria, renal diabetes. (05 Mar 2000) |
| renal epistaxis | Haematuria occurring without a detectable lesion. (05 Mar 2000) |
| renal failure | Chronic renal failure represents a slow decline in kidney function over time. Chronic renal failure may be caused by a number of disorders which include long-standing hypertension, diabetes, congestive heart failure, lupus or sickle cell anaemia. If renal function declines to a low enough level (end-stage renal disease) kidney dialysis may be necessary. A sudden decline in renal function may be triggered by a number of acute disease processes. Examples include sepsis (infection), shock, trauma, kidney stones, kidney infection, drug toxicity (aspirin or lithium), poisons or toxins (drug abuse) or after injection with an iodinated contrast dye (adverse effect). Both forms of renal failure result in a life-threatening metabolic derangement. (27 Sep 1997) |
