| middle kidney | <anatomy> The middle one of the three pairs of embryonic renal organs developed in most vertebrates; the Wolffian body. Origin: NL, fr. Gr. Middle + kidney. Source: Websters Dictionary (01 Mar 1998) |
|---|---|
| clear cell carcinoma of kidney | <radiology> Hypernephroma, renal cell carcinoma, arises from proximal collecting tubule, 10% bilateral adenocarcinoma types: papillary, alveolar, onchocytoma vascularity, 85% hypervascular (require pre-op embolization), 10% hypovascular (usually papillary type), 5% avascular associated with: tuberous sclerosis, von Hippel-Lindau syndrome see also: staging (12 Dec 1998) |
| wandering kidney | The abnormally mobile kidney in nephroptosia. Synonym: movable kidney, wandering kidney. (05 Mar 2000) |
| waxy kidney | A kidney in which amyloidosis has occurred, usually in association with some chronic illness such as multiple myeloma, tuberculosis, osteomyelitis, or other chronic suppurative inflammation; such kidney's are moderately enlarged and grossly manifest a waxy appearance, with amyloid deposited beneath the endothelium in the glomerular loops and in the arterioles, apparently beginning as foci of thickening of the basement membranes. Synonym: waxy kidney. (05 Mar 2000) |
| mortar kidney | A kidney containing caseous material trapped by stricture of the ureter due to tuberculous granulations in renal tuberculosis. Synonym: mortar kidney. (05 Mar 2000) |
| movable kidney | The abnormally mobile kidney in nephroptosia. Synonym: movable kidney, wandering kidney. (05 Mar 2000) |
| multicystic dysplastic kidney disease | <radiology> most severe form of renal dysplasia, most common cause of palpaple abdominal mass in infants, unilateral (almost always; if bilateral, death occurs in utero), ureter absent or atretic, not associated with other cysts or with periportal fibrosis, Potter type II (12 Dec 1998) |
| congenital kidney abnormalities | Kidney abnormalities that are present from birth (for example polycystic kidneys). (27 Sep 1997) |
| contracted kidney | A diffusely scarred kidney in which the relatively large amount of abnormal fibrous tissue and ischemic atrophy leads to a moderate or great reduction in the size of the organ, as in arteriolar nephrosclerosis and chronic glomerulonephritis. (05 Mar 2000) |
| convoluted part of kidney lobule | Proximal and distal convoluted tubules and the associated renal corpuscles supplied by branches of the interlobular arteries. Synonym: labyrinthus, pars convoluta lobuli corticalis renis, labyrinth, Ludwig's labyrinth, renal labyrinth. (05 Mar 2000) |
| convoluted tubule of kidney | The highly convoluted segments of the nephron in the renal labyrinth comprising the proximal convoluted tubule, which leads from Bowman's capsule to the descending limb of Henle's loop, and the distal convoluted tubule, which leads from the ascending limb of Henle's loop to the collecting tube. Synonym: tubulus renalis contortus, Ferrein's tube, tubulus contortus. (05 Mar 2000) |
| polycystic kidney | A progressive disease characterised by formation of multiple cysts of varying size scattered diffusely throughout both kidney's, resulting in compression and destruction of kidney parenchyma, usually with hypertension, gross haematuria, and uraemia; there are two major types: 1) with onset in infancy or early childhood, usually with autosomal recessive inheritance; 2) with onset in adulthood, with autosomal dominant inheritance. Synonym: polycystic disease of kidneys. (05 Mar 2000) |
| polycystic kidney disease | <disease> A rare inherited condition in which the kidney are composed of multiple cysts. Kidney cysts are associated with an increased incidence of cerebral aneurysm. Symptoms usually appear later (if they do at all) and include blood in the urine, flank pain, excessive urination at night and abdominal pain. Individuals may also have elevated blood pressure. Chronic (end-stage renal disease) renal failure is the most common result in the 5th to 6th decades of life. Incidence: 1 in 5,000. (02 Jan 1998) |
| cortical arches of kidney | The portions of renal substance (cortex) intervening between the bases of the pyramids and the capsule of the kidney. (05 Mar 2000) |
| cortical lobules of kidney | One of the subdivisions of the kidney, consisting of a medullary ray and that portion of the convoluted port (renal corpuscles and convoluted tubules) associated with its collecting duct. Synonym: lobulus corticalis renalis, renal cortical lobule, renculus, reniculus, renunculus. (05 Mar 2000) |
