Shadow On Kidney Ultrasound
Here are some. ..: A shadow on US indicates something blocking sound wave, usually stone (s), which will be further demonstrated with an abdomen film (KUB) since most of renal stones are radiopaque. More? Ask Doc timely for details. Best wishes. .. ...Read more
An ultraound, also known as a sonogram, is a painless and relatively inexpensive imaging test that utilizes sound waves instead of ionizing radiation. There are no side effects. Ultrasound can give us two-dimensional, and in some applications three-dimensional, images of structures and organs in virtually any part of the body. In addition to diagnostic uses, such as evaluating abnormalities in the abdomen, pelvis, and breast, ultrasounds are commonly used to guide needle and catheter placement in a variety of surgical ...Read more

The vast: Majority of these types of findings are of little or no concern. However, the ultrasound appearance is not specific, and you may need an additional test such as CT to confirm it. Tal to your doctor about th results. ...Read more
Had a renal sonogram and these were the findings "there are 2 hyperechoic foci, one in the mid/lower pole of the rt kidney of 4mm and one in the interpolar caliceal system on the lft of 5mm. These could represent nonobstructive calculi but no shadow?
Urologist suggests CT scan after xray and sonogram suggest kidney stones, but he saw only "shadow." Is CT scan necessary to confirm stones? No pain.
Aging of kidney: When a kidney ages, it acquires a condition called chronic kidney disease and appears bright on ultrasound. This usually appears in both kidneys, however, sometimes, a kidney appears bright before the other for different reasons e.g. If it has less good blood flow due to extra cholesterol plaques in blood vessels. Usually that kidney is a little smaller. Check your blood and urinalysis, though. ...Read more
Tough Question: Boy that's a tough question. Usually things that are bright on ultrasound are calculi (stones), air, or fat. If it were air the pt would likely be very sick. Fat is almost always benign, and stones can cause symptoms ranging from mild pain to sepsis. ...Read more

Kidney ultrasound measurements were 89mm x 42mm x34mm on left and 89mm x 33mm x 45mm on right. I'm 34, female. Should I be worried?
Depends on the size: It depends on how large the stones are. Very small stones should be able to pass without difficulty. Medium or large stones should probably be treated. If the stones are visible on a plain film xray, then eswl is a good option. Very large stones may require a more invasive procedure. Either way, it is important to increase your daily water intake to 2.5 to 3 l. ...Read more
Blood flow: Colors are genertaed during an ultrasound exam by software that detects motion occuring within the ultrasound beam. Standard colors are red and blue designated movement either towards the bam or away from the beam. Asdditional color gradients can indicate velocity and turbulence in the flow. Color in a kidney ultrasound indicates blood flow. ...Read more

I had an ultrasound of my kidneys. The dr stated there was "fluid on my kidney". I had just used the restroom. What does that mean?

Ultrasound showed Asymmetric thickening on the anterior aspect of left kidney. Should I be worried. No definite focal lesions were identified.
Here are some...: Need more info on general/specific history which was associated with why you got US of kidneys so to deduce the clinical significance of the asymmetric thickening on the anterior aspect of left kidney, although in reality it could be just a normal variation. If you need further evaluation with repeating US in 6-12 mons or a CT to further delineate what it may be, that should be decided by you & Dr ...Read more
My kidney function was not so good 5 months ago, but still in normal range, now on ultrasound, one kidney is 100mm and other 90mm, is this normal?
Normal size: The renal length varies with height and weight and decreases slowly with age. Right kidney is usually slightly smaller than the Left. Normal size ranges from 9-12 cm (90-120 mm) and the difference in size should not exceed 2 cm. **So the size of the kidneys is normal. Besides size the texture of the kidney (Its "Ecogenicity") is often increased in chronic renal disease. ...Read more

It is most: Likely OK and related to technical variations between the scans, but talk to your doc to make sure. ...Read more
Bright spots: Kidney stones show up on ultrasound as bright echogenic foci (white spots) within the substance of the kidney. If the stones are larger than 3 or 4 mm there will be a darker area behind the stone representing an acoustical shadow. Obstruction of the kidney by a stone will cause dilatation of the kidney's collecting system which will appear as black fluid spaces within the kidney. ...Read more
Yes: Ultrasound is a very good initial screening test for the kidneys. It can help identify kidney stones, obstruction of the kidneys, and tumors. If the ultrasound is questionable or clearly abnormal, a more specific imaging study is required such as a ct scan or MRI of the kidneys for further evaluation. Lesions seen ultrasound do not necessarily indicate cancer but further testing is warranted. ...Read more
Yes: If over 5 - 10 mm, it would show up. ...Read more
Easy peasy: Usually you will be asked to come with a full bladder. Gel will be placed on your skin and a tech will place a small device over the gel to take pictures, typically of your bladder first. It is painless. Then, you will likely be asked to empty bladder, then kidneys will be imaged same way. If you have ever seen a pregnant woman get an ultrasound it is the same thing, just in a different area. ...Read more
