A diagram showing the blood flow to the kidney. A theory for these effects is that the decrease in blood flow to the kidney results in hypoxia of the renal medulla, which then stimulates hypoxia-inducible factor, which in turn stimulates angiogenesis in the medulla. Erythropoietin is a stimulating factor for angiogenesis. Cited by 3 X-ray projections in the left anterior oblique view with the patient standing on the left, in the erect position. The reader should draw the renal vessels (black arrows). A direct line should be drawn between the most cephalad (uppermost) and caudad (lowest) portions of the renal arteries. The following files are available for download as PDF. Cited by 4 Renal function is controlled by the GFR and the RBF, which are only two of many factors that govern the filtration of the plasma. Cite from the following book. Each of these hormones has its own unique pattern of secretion and metabolic action. Each hormone also has a unique set of receptors. Thus, multiple kinds of chemical messengers can control renal function. From a certain volume of blood to a certain amount of urine is generally referred to as renal plasma flow. By altering the volume of blood that passes through the kidneys, which is known as renal blood flow, the body can alter its filtration rate and, therefore, its excretion of waste products. by Renal plasma flow (RFP) = GFR × Urine creatinine ratio. Cited by 2 Cite from the following book. Renal Blood Flow (RBF) is a comprehensive term that encompasses many specific aspects of renal function. All of the following statements (facts, concepts, or calculations) are true when the function of the kidney is considered as a whole: Renal blood flow (RBF) equals the rate of filtration and is not altered by antidiuretic hormone (ADH). In the presence of ADH, it equals the rate of excretion. Cited by 5 Renal blood flow (RBF) is diminished in acute tubular necrosis. The decreased RBF is secondary to decreased glomerular filtration. Cited by 1 If a person has normal renal blood flow, an elevation in the glomerular filtration rate should be accompanied by an elevation in the

28. To find your estimated GFR, the following formula can be used: eGFR = 175- (age in years) x 0. 007 (if female) x (SCr in mg/dl) x 1. Although all four hormones can stimulate renal growth, it is only IGF-I that plays a major role in kidney development and growth. Study of IGF-I, IGF binding proteins, and the renal IGF system provides a basis for understanding the role of IGF in regulating kidney growth. Cited by 13 The magnitude of the increase in RBF is less marked in the presence of a T-cell-mediated or an immunologic response. ○ Oxidative stress decreases the activity of the Na/H exchanger in tubules. by MN Inouye Cited by 21 Kidney function assessed by measurement of urea and creatinine clearance by W Shulman Cited by 11 Cited by 98 In this experiment, blood pressure is controlled by having a femoral artery and vein catheterized to give a steady arterial blood pressure of 100 mmHg. Cited by 2 The single most important determinant of RBF in normal children is the activity of the sodium pump. After a decrease in sodium pump activity, there is a compensatory increase in RBF. by A Brion Cited by 44 To measure glomerular filtration rate (GFR), the amount of filtrate is directly measured as urine flow. by JL James Cited by 29 To measure GFR in a chronic situation, isotopes are given intravenously and urine and serum are collected periodically. by RA Kitchell Cited by 30 2. GFR measurement in renal insufficiency To determine GFR in renal insufficiency, the following steps are taken: 1. by PJ Hanna Cited by 66 to be able to be used in a variety of situations, it is important to choose a test with a high sensitivity and a low specificity. 2. by W Braunwald Cited by 33 When this test is used to assess plasma clearance, the following formula can be used: clearance = U / P (A-B). 3. by W Braunwald Cited by 33 Glomerular filtration rate GFR is a reflection of both glomerular and tubular functions
