| TMPAH | maximum tubular excretory capacity for para-aminohippuric acid |
|---|---|
| TRF | T-cell replacing factor; thyrotropin-releasing factor; tubular rejection fraction |

| ARF | Acute Renal Failure |

| renal segments | Regions of the kidney supplied by end arteries branching from the renal arteries; they are named anterior inferior segmentum, anterius superior segmentum, inferior segmentum, posterior segmentum, and superior segmentum. Synonym: segmenta renalia, arterial segments of kidney. (05 Mar 2000) |
|---|---|
| renal sinus | The cavity of the kidney, containing the calyces and pelvis of the ureter and the segmental vesels embedded within a fatty matrix. The renal sinuses cause the kidneys to appear hollow or C-shaped on cross section or medical imaging. Synonym: sinus renalis. (05 Mar 2000) |
| renal-splanchnic steal | Diversion of blood from the right renal artery via the inferior adrenal branch into splanchnic collaterals distal to a stenosis of the coeliac axis. (05 Mar 2000) |
| renal-splenic venous shunt | Anastomosis of the splenic vein to the left renal vein, usually end-to-side, for control of portal hypertension. Synonym: renal-splenic venous shunt. (05 Mar 2000) |
| renal surface of spleen | The surface of the spleen in contact with the left kidney. Synonym: facies renalis lienis, facies renalis splenis. (05 Mar 2000) |
| renal surface of suprarenal gland | Surface of suprarenal gland in contact with the kidney. (05 Mar 2000) |
| renal surface of the suprarenal gland | The surface of the suprarenal gland in contact with the kidney. Synonym: renal surface of the suprarenal gland. (05 Mar 2000) |
| renal tb | <radiology> Putty kidney: caseous necrosis with calcium deposition, Cf: medullary nephrocalcinosis, renal calcification, haematogenous origin, clinically unilateral in 75%, findings: papillary necrosis, infundibular stenosis, autonephrectomy, CXR abnormal in 50% (12 Dec 1998) |
| renal threshold | Concentration of plasma substance above which the substance appears in the urine. (05 Mar 2000) |
| renal transplantation | Transplantation of a kidney from a compatible donor to restore kidney function in a recipient suffering from renal failure. (05 Mar 2000) |
| renal tubule | <anatomy> Small structures in the kidney that filter the blood and produce the urine. (12 Dec 1998) |
| renal vein | <anatomy, vein> The short thick veins which return blood from the kidneys to the vena cava. (25 Jun 1999) |
| renal veins | Large veins formed at the renal hilus by the merger of the segmental veins anterior to the corresponding arteries; they open at right angles into the inferior vena cava at the level of the second lumbar vertebra. The left renal vein receives the left suprarenal vein and the left gonadal vein, and passes through the angle between the abdominal aorta and superior mesenteric artery where it may be compressed. Synonym: venae renales. (05 Mar 2000) |
| glycosuria, renal | Glycosuria occurring when there is only the normal amount of sugar in the blood, due to inherited inability of the renal tubules to reabsorb glucose completely. (12 Dec 1998) |
| microcystic 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) |
