| 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) |
| 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) |

| 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) |
