| 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) |
| renal adenocarcinoma | <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) |
| renal adenocarcinoma: staging | <radiology> Typical presentation: Haematuria . . . . . 70% Fever . . . . . . . 16% Pain . . . . . . . . 50% Polycythemia . . . . 3% Palpable mass . . . 20% Anatomic staging (TNM): T1 Small tumour, kidney not enlarged T2 Large tumour, contained within renal capsule T3 Extension into perinephric fat or renal vein T4 Invasion of adjacent organs (12 Dec 1998) |
| renal adenocarcinoma: vascularity | <radiology> 85% hypervascular (require pre-op embolization), 10% hypovascular (usually the papillary type), 5% avascular also: 10% are bilateral (12 Dec 1998) |
| renal agenesis | <radiology> Associated with, duplicated vagina and/or uterus (mullerian duct anomaly), seminal vesicle cysts (12 Dec 1998) |
| renal agents | Drugs used for their effects on the kidneys' regulation of body fluid composition and volume. The most commonly used are the diuretics. Also included are drugs used for their antidiuretic and uricosuric actions, for their effects on the kidneys' clearance of other drugs, and for diagnosis of renal function. (12 Dec 1998) |
| renal amyloidosis | Renal deposits of amyloid, especially in glomerular capillary walls, which may cause albuminuria and the nephrotic syndrome. Synonym: amyloid nephrosis. (05 Mar 2000) |
| renal artery | <anatomy, artery> A branch of the abdominal aorta which supplies the kidneys, adrenal glands and ureters. (12 Dec 1998) |
| renal artery obstruction | Narrowing or occlusion of the renal arteries. It is due usually to atherosclerosis, fibromuscular dysplasia, thrombosis, embolism, or external pressure. It may result in renovascular hypertension. (12 Dec 1998) |
| renal artery stenosis | <cardiology, nephrology> A narrowing of the renal artery or one of its main branches accounts for 2 to 5% of cases of hypertension. (27 Sep 1997) |
| renal ballottement | A manoeuvre in which the kidney is moved by pressure from behind, allowing it to be felt between the hands and its size, shape, and mobility determined. (05 Mar 2000) |
| renal blood flow, effective | The amount of blood flowing to the parts of the kidney that are involved with the production of constituents of urine. It is that portion of the total renal blood flow that perfuses functional renal tissue (e.g., the glomeruli). It should be differentiated from renal plasma flow, effective which is based on the amount of plasma rather than on total renal blood. (12 Dec 1998) |
| renal branch of lesser splanchnic nerve | <anatomy, nerve> Branch of lesser splanchnic nerve to the aorticorenal plexus/ganglion. Synonym: ramus renalis nervi splanchnici minoris. (05 Mar 2000) |
