| calices | Plural of calix. (05 Mar 2000) |
|---|---|
| calices renales majores | The primary subdivisions of the renal pelvis, usually two or three in number. Synonym: calices renales majores. (05 Mar 2000) |
| calices renales minores | The subdivisions of the major calices, varying in number from 7 to 13, which receive the renal papillae. Synonym: calices renales minores. (05 Mar 2000) |
| major calices | The primary subdivisions of the renal pelvis, usually two or three in number. Synonym: calices renales majores. (05 Mar 2000) |
| minor calices | The subdivisions of the major calices, varying in number from 7 to 13, which receive the renal papillae. Synonym: calices renales minores. (05 Mar 2000) |
| 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) |
| acute renal failure | <nephrology> 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). 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. Both forms of renal failure result in a life-threatening metabolic derangement. (27 Sep 1997) |
| aminoaciduria, renal | Impairment of renal tubular transport of amino acids. (12 Dec 1998) |
| back-pressure renal atrophy | <radiology> Caliectasis without obstruction, due to repeated episodes of obstruction, gradual loss of renal pyramids (12 Dec 1998) |
| base of renal pyramid | The outer broad part of a renal pyramid that lies next to the cortex. Synonym: basis pyramidis renis. (05 Mar 2000) |
| branchio-oto-renal syndrome | <syndrome> An autosomal dominant disorder manifested by various combinations of preauricular pits, branchial fistulae or cysts, lacrimal duct stenosis, hearing loss, structural defects of the outer, middle, or inner ear, and renal dysplasia. Associated defects include asthenic habitus, long narrow facies, constricted palate, deep overbite, and myopia. Hearing loss may be due to mondini type cochlear defect and stapes fixation. (12 Dec 1998) |
| capsular branches of renal artery | <anatomy, artery> Branches arising from the renal artery outside of the kidney that are distributed to the renal capsule. Synonym: rami capsulares arteriae renalis. (05 Mar 2000) |
| captopril renal scan | <radiology> In a kidney with a lesion in the afferent arteriole (e.g. Atherosclerotic plaque), reflex constriction of the efferent arteriole occurs through angiotensin system thus maintaining renal perfusion. ACE inhibition prevents constriction of efferent arteriole. Therefore, perfusion is decreased to a kidney with afferent lesions and the renal scan to looks WORSE. Bottom line: renal scans appear WORSE with captopril administration if there is a lesion in the afferent arteriole. See: renal artery stenosis (12 Dec 1998) |
| carcinoma, renal cell | Carcinoma of the renal parenchyma usually occurring in middle age or later and composed of tubular cells in varying arrangements. It was first described in 1826. Possible causal factors are environmental, hormonal, cellular, and genetic. Smoking is a definite risk factor and obesity is associated with increased risk. Renal cell carcinoma accounts for approximately 3% of adult cancer; the male-female ratio is 2:1. It is more common among urban residents than rural. (12 Dec 1998) |
| renal | <anatomy> Pertaining to the kidney, nephric. (18 Nov 1997) |
