| arteries of kidney | The branches of the renal artery that supply the anatomical segments of kidney. Usually five in number, they are end arteries and give off interlobar, arcuate and interlobular arteries in sequence. The latter send afferent arterioles to the glomeruli as well as branches to the kidney capsule. The segmental arteries of the kidney are identified as: anterior inferior (arteriae segmenti anterioris inferioris renis ); anterior superior (arteriae segmenti anterioris superioris renis ); inferior (arteriae segmenti inferioris renis ); posterior (arteriae segmenti posterioris renis ); and superior (arteriae segmenti superioris renis ). Synonym: arteriae renis, arteries of kidney. (05 Mar 2000) |

| arteriolosclerotic kidney | A kidney in which there is sclerosis of the arterioles, i.e., arteriolar nephrosclerosis resulting from long-standing benign hypertension. Such kidney's tend to be pale red-brown or relatively gray, moderately reduced in size, and firmer than normal organs; the capsular surfaces are uniformly finely granular. Most of the arterioles are thickened and hyalinised, thereby resulting in varying degrees of narrowing of the lumens, ischemia, and fibrosis in the interstitial tissue, leading to uniform contraction of the cortex. (05 Mar 2000) |
| arteriosclerotic kidney | A kidney in which there is sclerosis of arterial vessels larger than arterioles. Such kidney's are usually not significantly reduced in size, but are likely to be paler than usual; the capsular surface may be marked by a few, possibly several, conical, relatively deep V-shaped scars that result from fibrosis and ischemic atrophy of the region supplied by the affected vessel.

| artery of anterior inferior segment of kidney | Origin, anterior branch of renal. See: segmental arteries of kidney. Synonym: arteria segmenti anterioris inferioris renis, artery of anterior {inferior segment of kidney}. (05 Mar 2000) |
| artery of anterior superior segment of kidney | Origin, anterior branch of renal. See: segmental arteries of kidney. Synonym: arteria segmenti anterioris superioris renis, artery of anterior {superior segment of kidney}. (05 Mar 2000) |
| artery of inferior segment of kidney | Origin, anterior branch of renal. See: segmental arteries of kidney. Synonym: arteria segmenti inferioris renis, artery of inferior segment of kidney. (05 Mar 2000) |
| artery of posterior segment of kidney | Origin, continuation of the posterior branch of renal. See: segmental arteries of kidney. Synonym: arteria segmenti posterioris renis, artery of posterior segment of kidney. (05 Mar 2000) |
| artery of superior segment of kidney | Origin, anterior branch of renal. See: segmental arteries of kidney. Synonym: arteria segmenti superioris renis, artery of superior segment of kidney. (05 Mar 2000) |
| artificial kidney | A machine for haemodialysis in acute or chronic renal failure; toxic substances in the blood are removed by exposure to dialyzing fluid across a semipermeable membrane. Synonym: artificial kidney. Ultrafiltration haemodialyzer, a haemodialyzer that uses fluid pressure differentials to bring about loss (usually) of protein-free fluid from the blood to the bath, as in certain edematous conditions.

| ask-upmark kidney | <radiology> Segmental renal hypoplasia, gross findings: same as unifocal reflux nephropathy, (?) due to STERILE intrarenal reflux (12 Dec 1998) |
| atrophic kidney | A kidney that is diminished in size because of inadequate circulation and/or loss of nephrons. (05 Mar 2000) |
| cake kidney | A solid, irregularly lobed organ of bizarre shape, usually situated in the pelvis toward the midline, produced by fusion of the renal anlagen. (05 Mar 2000) |
| cancer, kidney | Cancer of the major organ responsible for the removal from the blood of the toxins of body metabolism the kidney. Childhood kidney cancer is different from the adult kidney cancer. The most common symptom of kidney cancer is blood in the urine. The diagnosis of kidney cancer is supported by findings of the medical history and examination, blood, urine, and X-ray tests, and confirmed with a biopsy. Kidney cancer is treated with surgery, embolization, radiation therapy, hormone therapy, biological therapy, or chemotherapy. (12 Dec 1998) |
| page kidney | <radiology> Renal compression most likely to be hypertension, mediated by renin-angiotensin system, aetiology: haematoma (posttraumatic) -- most common, cyst, tumour, on angio: stretching and splaying of intrarenal vessels (12 Dec 1998) |
| pancake kidney | A disk-shaped organ produced by fusion of both poles of the contralateral kidney anlagen. Synonym: disk kidney. (05 Mar 2000) |
