| 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) |
| solid renal mass | <radiology> MALIGNANT until proven otherwise!, renal cell carcinoma (85%), other malignancy (10%), renal sarcoma, lymphoma, transitional cell carcinoma, metastases, benign mass (5%), oncocytoma, angiomyolipoma (fat present), fibroma (12 Dec 1998) |
| osteopetrosis with renal tubular acidosis | <syndrome> An inherited deficiency of carbonic anhydrase II that results in osteopetrosis and metabolic acidosis. Synonym: osteopetrosis with renal tubular acidosis. (05 Mar 2000) |
| effective renal blood flow | The amount of blood flowing to the parts of the kidney that are involved with production of constituents of urine. (05 Mar 2000) |
| effective renal plasma flow | <physiology> The amount of plasma flowing to the parts of the kidney that have a function in the production of constituents of urine; the clearance of substances such as iodopyracet and p-aminohippuric acid, assuming that the extraction ratio in the peritubular capillaries is 100%. It is the amount of plasma perfusing the kidney tubules per unit time, generally measured by p-aminohippurate clearance. It should be differentiated from renal plasma flow which is approximately 10% greater than the effective renal plasma flow. (07 Mar 2000) |
| end-stage renal disease | <nephrology> A patient with inadequate renal function to support life. Individuals with end-stage disease must rely in kidney dialysis or peritoneal dialysis to survive. End-stage renal disease may be caused by a number of problems including diabetes, sickle cell disease, hypertension and congenital renal disease (polycystic kidney disease). (27 Sep 1997) |
| tuberculosis, renal | Infection of the kidney with species of mycobacterium. (12 Dec 1998) |
| fatty renal capsule | The perirenal fat. Synonym: capsula adiposa renis, adipose capsule. (05 Mar 2000) |
| ureteric branches of the renal artery | <anatomy, artery> Supplies ureteric (renal) pelvis and superior portion of ureter. Synonym: rami ureterici arteriae renalis. (05 Mar 2000) |
| filling defect in renal collecting system | <radiology> Common causes: transitional cell carcinoma, blood clot, lucent calculus (urate) less common causes: fungus ball, sloughed papilla, fibroepithelial polyp, invasion by hypernephroma, malakoplakia, vessel impression, metastases (12 Dec 1998) |
