what the risks are kidney anatomy, kidney, blood, urine flow, renogram, kidney scan, a renal scan, nuclear medicine examination that uses small amounts of radioactive materials, radioisotopes, to measure the function, the kidneys, a renal scan is similar to, in fact, a continuation of, a renal perfusion scintiscan, lie on the scanner table, pressure, a tourniquet, blood pressure cuff, applied, upper arm, distends the veins, the arm, inner elbow is scrubbed, antiseptic, a small amount, radioisotope is injected into a vein, radioisotope used, vary depending on the portion of kidney function that is of particular interest, in the study, pressure on the upper arm is then released, allows the isotope to travel, the bloodstream, a small, concentrated "package", a short time later, kidneys, scanned, several images, each lasting 1, 2 seconds, the total scan time, 30 minutes to 1 hour, images, analyzed by a computer, scan is completed, give detailed information, particular kidney functions, glomerular filtration rate, reflects how much blood the kidney filters over time, scan, no recovery time, drink plenty of fluids, urinate frequently to help excrete the radioactive material, there, no need, fasting, special diets, preliminary medications, discuss, health care professional any nonsteroidal anti-inflammatory drugs, nsaids, blood pressure medications, currently taking, interfere, the exam, drink additional fluids, the scan, must sign a consent form, wear a hospital gown, remove jewelry, dentures, metallic objects, the scan, infants, children, test depends on child's age, prepare child, infant test, procedure preparation, birth to 1 year, toddler test, procedure preparation, 1 to 3 years, preschooler test, procedure preparation, 3 to 6 years, schoolage test, procedure preparation, 6 to 12 years, adolescent test, procedure preparation, 12 to 18 years, sharp prick, the isotope is injected, vein, not feel the isotope, not feel the scan, the table hard, cold, lie still, scan, test evaluates the size, position, function, the kidneys, a renal scan is particularly useful, known sensitivity, contrast media used in an ivp, x-rays, underlying kidney insufficiency, reduced kidney function, renal scan is commonly used after a kidney transplant to evaluate kidney function, to look, signs of transplant rejection, a renal scan, evaluate kidney function, hypertension abnormal results indicate reduced kidney functions, acute, chronic renal failure, complications of a kidney transplant, surgical complications, transplant rejection, glomerulonephritis, kidney disorders, additional conditions under which the test performed, acute arterial occlusion, the kidney, acute bilateral obstructive uropathy, bilateral hydronephrosis, carcinoma, the renal pelvis, ureter, chronic bilateral obstructive uropathy, complicated uti, pyelonephritis, injury, the kidney, ureter, pyelonephritis, acute, renovascular hypertension risks, essentially the same, x-rays, radiation, needle pricks, slight amount, radiation, radioisotope, most of this radiation exposure occurs, kidneys, bladder, the isotope is excreted, virtually all radiation is gone, body in 24 hours, the slight exposure to radiation, caution is advised, pregnant, breastfeeding, time the body is penetrated, by a needle prick, risk, infection, injection into a vein also carries a slight risk, bleeding, risk is no greater, renal perfusion scan than, intravenous injection of any sort, extremely rarely, exhibit an allergic reaction, radioisotope, severe anaphylaxis a scan that shows reduced kidney function help identify the cause, the problem, congenital, present from birth, abnormalities of kidney shape, contribute to an error in interpreting results of thel scan, glomerular filtration rate, functions, calculated, normal kidney size, tests of some functions, require delayed images, 1 to 4 hours later, advantages, the scan, the ability, kidney function, exposure to contrast agents, ability, obtain quantitative information, not be obtainable by other procedures.
