What Is Involved Exactly In A Pediatric Renal Tract Ultrasound
Very easy exam: Just as when you were pregnant, they put the gel on the abdomen and ultrasound the kidneys, the ureters, the bladder and the urethra. It is not painful and is tolerated very easily. There is a preparation for the exam. They usually want you to drink quite a bit and not urinate until after the exam. Then they ultrasound the bladder once it is emptied as well. ...Read moreSee 1 more doctor answer
The sonogram is a test that looks at body organs with no radiation. It uses sound waves and can give us a 2 dimensional view of organs such as the kidney, liver, heart, and lungs. It can define spaces that are either solid or full of fluid. I can also guide large needles into an organ or near the spine, and can help define the area being cut open. Its a ...Read more
Not pyelonephritis: Renal ultrasound can not detect pyelonephritis unless there is appreciable swelling of part or all of the kidney. It is excellent for demonstrating kidney cysts, hydronephrosis or kidney obstruction. Will demonstrate large and obstructing kidney stones but can and will miss small kidney stones smaller especially smaller than 3mm. ...Read moreSee 1 more doctor answer
Renal ultrasound: Renal artery ultrasound is called "renal duplex" which originally combined B-mode ultrasound to image the renal arteries with a pulsed Doppler to sample the velocity of blood flow in the artery. Now color Doppler and other extras are available. If renal velocity>200cm/sec artery likely abnormal. If RAR (ratio of renal velocity over aortic velocity) >3.5 likely 60% stenosis present. Accuracy good. ...Read moreSee 2 more doctor answers
Using sound waves : Renal us uses sound waves to pass through the tissues to make black and white images of the kidney tissue and urinary bladder. It is painless and uses no dye. It takes about 20 minutes to perform and is interpretted by a licsenced doctor called a radiologist. ...Read moreSee 1 more doctor answer
See below: Renal artery ultrasound is using a special probe with the ultrasound machine to detect blood flow, and blockage if any in the artery. Ultrasound employ high frequency sound waves which bounce of structures within the abdomen in this case and are converted into a picture for analysis.It is my opinion that this is not a very sensitive test for native kidneys and I do not use it. ...Read moreSee 1 more doctor answer
At 20 week ultrasound, the baby's kidney showed renal pelvis dilation with calyceal dilation at 6 mm for both kidneys. There was no blockage in ureter. Opinions?
No question here: If you are asking "is there blockage in the ureter?" then the answer is possibly. Significant dilation in early gestation increases this risk. It is important to know that dilation (hydronephrosis) can occur without obstruction as well. If the amniotic fluid is low, see a pediatric urologist for prenatal consultation, particularly if you are having a boy (risk of urethral obstruction is high). ...Read moreSee 2 more doctor answers
Kidney health: Usually a kidney sonogram will show if there is an obstruction to the kidney flow, will tell if kidney disease is a chronic one and will show cysts, masses and kidney stones if present. Sometimes it may show congenital anomalies of the urinary tract. ...Read moreSee 1 more doctor answer
Renal ultrasound.: Renal ultrasound can find blockages of the urine in the urinary tract or bladder, blockages of the arteries the feed the kidneys blood, kidney size, kidney cysts (and polycystic kidney disease), sometimes but not always kidney stones, and kidney tumors.Since it uses sound waves to create images of the kidney, it is safe, but operator dependent and the images are subject to erroneous interpretation. ...Read moreSee 1 more doctor answer
