| 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) |

| 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) |

| split renal function test | A study performed to determine various functional parameters of one kidney compared to the contralateral kidney; ureteral catheters are inserted at cystoscopy into the ureter or renal pelvis bilaterally, and simultaneous measurements are made of urine flow rate, insulin, or PAH (if infused), endogenous creatinine, or various urinary solutes. Synonym: differential renal function test, split renal function test. (05 Mar 2000) |
