Will Kidney Stones Show Up On Ultrasound
It it possible for kidney stones to show up on ultrasound and not of CT scan if so what kind of stones would they be (uric acid)?
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

Yes, depends on seve: If the blockage is complete & urine backs up into the kidneys, you can get a condition called hydronephrosis. This can be detected on ultrasound due to the dilation of the ducts in the kidneys (like stepping on a garden hose- water backs up & bulges). Ultrasound can miss a kidney stone due to its location or size; however, it can detect the *effects* of a kidney stone, by which diagnosis is made. ...Read more

No: Ct and ultrasound does not "always" show kidney stones. The resolution may not be sensitive enough to see very small stones less than 2 to 3 mm. Depending on the thickness of the images on the ct scan, a stone may be potentially missed between the images taken by the ct scanner. Ultrasound may also over-read or miss very small stones as well. Overall though, the detection rate is still very hi. ...Read more

Urologist ordered CAT bc blood in urine and an earlier ultrasound that showed 4 kidney stones. What body parts will show up in the CAT scan?
Abdomen and pelvis: The CT scan ordered when a patient has blood in the urine is of the abdomen and pelvis. It will show the kidneys, ureters, bladder and will also incidentally show the liver, lower lobes of lungs and spleen. Normally contrast is given intravenously when checking on urinary bleeding. Best wishes. ...Read more
I was sent to get a blood test because of kidney stones that a sonogram revealed I have. My results show that my MPV is high at 12.7 Is that normal?
MPV=mean platelet volume
This is a little used value in thehemograom, with only weak correlation with disease states. Like red cells, younger platelets tend to be bigger, and stress reactions may prompt earlier release from the marrow. Many possible causes, but little utility in isolation. ...Read more
Blood in urine reoccuing UTI CT scan 3mm kidney stone bladder ultra sound scan shows bladder not emptying proper what could this be?
Cystitis.: Gross hematuria probably as a result of cystitis caused by the bladder outlet narrowing or stenosis and not because of the kidney stone. By drinking more water like 8 cups a day you can pass the kidney stone. For the cystitis you need urine culture . Until the culture result comes back you can be put on an antibiotic such as cipro (ciprofloxacin) to stop the gross hematuria. ...Read more
Yes frequently: Small stones can easily be missed, by any ultrasound machine especially by office ultrasound machines. Spiral ct scan is the most reliable imaging tool for small kidney stones. Flank pain & microscopic blood in urine are frequently good clues to presence of stones. Good news is that small kidney stones usually pass spontaneously & require no intervention. ...Read more
Yes: Ultrasound may not see the stone well but may see swelling in the tube (ureter) where a stone has clogged up the drain. A cat scan (ct) is usually the preferred test to better see the stones. But, unlike ultrasound exposes you to some radiation. ...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
What to do if I had a kidney stone and hydronephrosis last year, but when I do ultrasound this year?
Why not treated?: U hopefully consulted a urologist last year. Dr should have outlined a plan. U don't tell us whether the kidney stone was treated or not. We also do not know whether hydronephrosis was result of stone or not. Thus advise U contact urologist U saw before, or consult a urologist if U haven't done so before. ...Read more

Just...: For your clinical scenario, i would probably just review hx pertaining to stone clinical activity, get a kub if prior stone was radiopaque, and urinalysis, with US only for the first year after care for stone and its related hydronephrosis. That sounds reasonable. Detail? Ask urologist. ...Read more
35 year old husband has 7mm kidney stone found on ultrasound by accident. He keeps getting these tiny stones. He has no symptoms. Is this serious?
On ultrasound it says there are a few kidney stones and one is .9 cm x .6 cm. I have no pain though. It says interpolar area. Can it just be watched?
Get to urologist: who can give you specific advice. I think you should try medical management before you have a surgical procedure as long as you have no symptoms. But a lot depends on your age and general medical condition. ...Read more
Depends: For renal stones (in kidney), ultrasound is usually adequate. Can also see dilation of the kidney when stone is blocking the outflow tube (ureter). For better clear picture and to see ureteral stones which are closer to bladder, ct scan is better. However, all ctscans must be considered carefully given the radiation exposure to the patient which ultrasound does not have. ...Read more
Is it possible to have kidney stones, but not have any evidence of them in urine samples or ultrasounds?
Yes: These stones may be too small see on ultrasound and a routine urinalysis may easily miss stones as well. The best test for diagnosing the majority of stones in the urinary tract is a ct scan without contrast. This will detect the majority of kidney stones but a few may be missed occasionally. ...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
My fiancee got a kidney stone of 6mm in size according to the ultrasound, is it possible to pass it without surgery?
Ureteral stone: The size of the stone does not correlate well to the intensity of the pain. The nearly unbearable pain of "ureteral colic" is from spasm of the muscular ureter. Although likely to pass on its own within a few days, a 3mm stone sometimes will get stuck and fail to progress. A 6mm stone, less likely usually after 5 days, i recommend having the stone extracted with a ureteroscope as an outpatient. ...Read more
I recently had an ultrasound of my right kidney where a kidney stone was found along with a 3mm bright echo was found. Should i be concerned?
Increased use of us or ct to evaluate body pain had led to finding small asymptomatic stone or mass in kidneys, lungs, liver, etc. Which is incidental and poses substantial dilemma on how to handle these subclinical findings. For kidney stone of 3 mm, i would leave it alone if you have no stone-related symptoms., but followed yearly with a x-ray film (kub).
More detailing, work with urologist. ...Read more
