| chronic renal failure | <nephrology> 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. If renal function declines to a low enough level (end-stage renal disease) kidney dialysis may be necessary. 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). Both forms of renal failure result in a life-threatening metabolic derangement. (27 Sep 1997) |

| multiple renal cysts | <radiology> Adult (autosomal-dominant) polycystic kidney disease, multiple simple cysts, tuberous sclerosis, von Hippel-Lindau syndrome, Meckel-Gruber syndrome (12 Dec 1998) |
| cribriform area of the renal papilla | The apex of a renal papilla pierced by 10 to 22 openings of the papillary ducts, the foramina papillaria. Synonym: area cribrosa papillae renalis. (05 Mar 2000) |
| posterior branch of renal artery | <anatomy, artery> Terminal branch of renal artery (with anterior branch) becoming the posterior segmental artery of kidney. Synonym: ramus posterior arteriae renalis. (05 Mar 2000) |
| crossed renal ectopia | <radiology> M more than F, right (67%), may fuse: crossed-fused renal ectopia (12 Dec 1998) |
| haematologic, gastrointestinal, and renal agents | A collective grouping for agents that act on the haematopoietic, gastrointestinal, and renal systems. (12 Dec 1998) |
| haemorrhagic fever with renal syndrome | <syndrome> An acute febrile disease occurring predominately in asia. It is characterised by fever, prostration, vomiting, haemorrhagic phenonema, shock, and renal failure. It is caused by any one of several closely related species of the genus hantavirus. The most severe form is caused by hantaan virus whose natural host is the rodent apodemus agrarius. A milder form is caused by seoul virus and related species and transmitted by the rodents rattus rattus and r. Norvegicus. (12 Dec 1998) |
| cystic disease of renal medulla | Presence of small cysts in the renal medulla associated with anaemia, sodium depletion, and chronic renal failure. It is of two types: 1) fatal autosomal recessive or juvenile type (also called familial juvenile nephrophthisis), beginning at about age 10 with an average duration of 6 to 8 years; 2) autosomal dominant or adult type, beginning at about age 30 but with a more fulminant course. Synonym: microcystic disease of renal medulla. (05 Mar 2000) |
| primary renal calculus | A calculus formed in an apparently healthy urinary tract, usually composed of oxalates, urates, or cystine. (05 Mar 2000) |
| primary renal tubular acidosis | A metabolic defect in the mechanism of urinary acidification that may be either the transient type, with onset in infancy, or the persistent type, with onset in childhood or adult years; both types are familial. (05 Mar 2000) |
| secondary renal calculus | A calculus associated with infection and/or obstruction, usually composed of struvite (magnesium ammonium phosphate). Synonym: infection calculus. (05 Mar 2000) |
| secondary renal tubular acidosis | Renal tubular acidosis that may occur as a complication of hypercalcaemic states, hyperglobulinaemic disorders, and in some other chronic renal conditions; a regular component of De Toni-Fanconi syndrome. (05 Mar 2000) |
| hypertension, renal | Hypertension due to renal diseases, especially chronic parenchymal disease. Hypertension as a result of compression or obstruction of the renal artery or its branches is hypertension, renovascular. (12 Dec 1998) |
