| 영문 | renal transplantation | 한글 | 콩팥이식 |
|---|---|---|---|
| 설명 | 콩팥병을 가지고 있으나 치료가 불가능한 만성콩팥기능상실 등의 질병을 가진 환자의 신장을 떼어내고 환자와 항원성이 유사한 사람의 콩팥을 이식해주는 것. 이 때 서로간의 항원성의 유사점이 많아야 거부반응이 일어나지 않는다. 그리고 일단 콩팥이식을 받은 사람은 오랜기간 동안 면역억제제를 투여하여 거부반응을 줄여야 한다. 대개 이식된 콩팥은 엉덩뼈오목에 위치하게 된다. |

| osmolal clearance | The volume of urine that would be excreted per minute if the urinary solutes were accompanied by just enough water to make the urine isosmotic with plasma, i.e., so that the solute excretion did not change the osmolality of body fluids. To calculate it, the volume of urine excreted per minute is multiplied by the urinary osmolality (usually measured by freezing point depression) and divided by the plasma osmolality. Osmolal clearance is less than actual urine flow when urine is hyposmotic and exceeds it when urine is hyperosmotic. (05 Mar 2000) |

| endogenous creatinine clearance | A term distinguishing measurements based on the creatinine normally present in plasma; since no infusion is necessary, an average value may be obtained by collecting urine for a long period, e.g., 24 hours. (05 Mar 2000) |
| exogenous creatinine clearance | A term distinguishing measurements based on infusing creatinine intravenously to raise its plasma concentration and facilitate its accurate chemical determination. (05 Mar 2000) |
| urea clearance | The volume of plasma (or blood) that would be completely cleared of urea by one minute's excretion of urine; originally calculated as urine flow multiplied by urine urea concentration divided by concentration of urea in whole blood rather than plasma, representing blood urea clearance rather than plasma urea clearance. (05 Mar 2000) |
| urea clearance test | A test of renal function based on urea clearance. (05 Mar 2000) |
| free water clearance | The amount of water excreted in the urine beyond that which would accompany the excreted solutes if the urine were isosmotic with plasma; it represents the loss of body water in excess of solute tending to raise body osmolality and making urine hyposmotic. Unlike other clearance's, it is calculated by subtracting the osmolal clearance from the actual volume of urine excreted per minute. A negative value for free water clearance represents the amount of water that the body has reclaimed from isosmotic tubule fluid to make the urine hyperosmotic and to lower body osmolality.

| 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) |
