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)?

Uric acid stones: Yes, this is possible: Uric acid stones are not very radio-opaque - so plain XRAY miss them; so might CT, unless contrast is used. Ultrasound will not miss them, unless small - less than 5 mm

Sonogram (Definition)

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

Can a ultrasound show a kidney stone blockage thanks?

Can a ultrasound show a kidney stone blockage thanks?

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.

Please tell me, could a kidney stone not show on ultrasound?

Please tell me, could a kidney stone not show on ultrasound?

Some may not: Some kidney stones may not show on ultrasound. If the stones are less than 3mm the ultrasound exam may not be able to detect in some cases cat scan is the standard test used in us to diagnose kidney stones, but it does involve risk of radiation as compared to ultrasound.

Does a CT or ultrasound always show kidney stones?

Does a CT or ultrasound always show kidney stones?

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.

The same for other Q: The findings of UA fit well with kidney stones, which require no urgent care, but advisable to be counseled for expectation. To gain more ideas on how to handle hematuria, please peruse a brief article in http://www. Formefirst. Com/hematuria. Html. Best wishes to health, happiness, and success.

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?

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.

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?

Platelets: 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.

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.

Do ultrasounds ever miss kidney stones?

Do ultrasounds ever miss kidney stones?

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.

Can kidney stones be found with an ultrasound?

Can kidney stones be found with an ultrasound?

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.

Describe an ultrasound procedure for kidney stones?

Describe an ultrasound procedure for kidney stones?

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.

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.

I had an ultrasound done and it showed a 6-7mm kidney stone. The X-ray showed clear. What one is right?

I had an ultrasound done and it showed a 6-7mm kidney stone. The X-ray showed clear. What one is right?

Stones: A small kidney stones detected by ultrasound can sometimes be missed in plain x-rays. You should go with the ultrasound results. They are small and in your case asymptomatic in many cases they pass on their own hydrate yourself well and read about diet that decreases future stone formation.

What do you advise if I had a kidney stone and hydronephrosis last year, but when I do ultrasound this year?

What do you advise if I had a kidney stone and hydronephrosis last year, but when I do ultrasound this year?

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.

Kidney (Definition)

The kidneys are paired organs that lie on either side of the vertebral column. Part of their critical functions include the excretion of urine and removal of nitrogenous wastes products from the blood. They regulate acid-base, electrolyte, fluid balance and blood pressure. Through hormonal signals, the kidneys control the ...Read more


Kidney Stone (Definition)

Solutes precipitate and combine to form stones formed of calcium oxalate usually around a nidus of uric acid. Other solutes that form stones are ca and mg phosphates, cystine, and uric acid staghorn calculi form in the presence of chronic urinary tract infections. Stones can be painful, may require ...Read more
