Kidney Stone Not Showing Up On Ct Scan
Ct uses xrays taken an 360 degrees combined with a computer to see"inside" the body. The table moves as the xray tube and detectors spin around the patient 10 times a second or more! the image shows excellent soft tissue detail, enhanced with injection of intravenous contrast or oral contrast. This way the body is shown in slices, in any plane, usually axially, but ...Read more
Could bladder cancer show up on CT scan done for kidney stones? Came back clear.Also had l-spine xray that was clear for any abnormalities.
Yes: In fact, ct scanning without contrast is becoming the gold standard evaluation for kidney stones. Contrast material frequently obscures stones and makes their identification difficult. Stones as small as 1 mm can be detected with unenhanced ct technique. Radiolucent stones which cannot be seen well with plain x-ray technique do show up well with unenhanced ct scan. ...Read more
Had CT scan w/o contrast of kidneys to check for kidney stones and it came back normal. Would tumors and cysts also have shown up on the CT scan i had?
Yes but: Kidney tumors and cysts will show on a non-contast CT scan.However if there is a hyperdense cyst(due to hemorrhagic proteinaceous material in it) it cannot be distinguished from tumor without contrast. When contrast is given,a tumor will enhance(it will appear white)but a cyst will not enhance.I don't think you need to worry about tumor at age 33.Extremely rare.I'm glad you had no stones. ...Read moreSee 2 more doctor answers
Would a CT scan on the abdomen without contrast show kidney stones or gallbladder inflammation better than ultrasound?
CT for stones: Ct without contrast is much better than us for kidney and ureter stones. Ct detects calcium better. Most gallbladder disease involves inflammation. Us is better for right upper quadrant pain and suspected gallbladder disease. It is also cheaper and involves no radiation, so it is arguably safer over a person's lifetime. ...Read moreSee 1 more doctor answer
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.
CT scans are: more accurate than ultrasound for diagnosis of kidney stones and other anatomical abnormalities of kidneys such as tumors. If you are having painless hematuria, this condition raises suspicion of possible tumor in urinary tract. ...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 moreSee 1 more doctor answer
Would a CT scan show gallstones because my CT scan came back clear. Also, would a CT scan combined with urine tests and blood tests detect gallstones?
22days post ureteroscopic kidney stone removal&stent placement still passing stones not on CT ? Scans show nonobstructing stones how can this be?
Possible: It is good to pass the stones- obstructing or non- obstructing is only a matter of size of the stone and diameter of the ureter ( which is the tube from kidney to the bladder) small size stones may not be seen on ct. Check with your doctor- if kidney stones is a recurrent issue, may benefit if you see a nephrologist who can do some special tests and advise preventive measures. ...Read moreSee 2 more doctor answers
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

3mm stone show up on ultrasound , then I had a CT scan and it show no stones , so was the ultrasound wrong ? Or other blood in urine and pain sti
Stone: Ct scan is much more sensitive than an ultrasound study for identifying smaller kidney stone. However due to recent concerns raised in the media about the radiation exposure from ct, many practitioners have gone toward using ultrasound as a first line study.
