Is there such thing as an ultrasound for kidney? I have microscopic hematuria. Urine 500++

Is there such thing as an ultrasound for kidney? I have microscopic hematuria. Urine 500++

Yes: Ultrasound of the kidney is relatively quick, painless, and uses no ionizing radiation, so it is often the first imaging study performed to evaluate the kidneys. It may identify a potential cause of the hematuria. If it doesn't, further tests may need to be done. ...Read more

Urine (Definition)

Urine is the product of the kidneys, which is produced to eliminate the waste products of metabolism, manage body fluid balance, &maintain acid-base balance. The blood is first filtered by the kidneys, and the composition of the resulting fluid is then altered depending on the body's needs. It is composed of mostly water, and breakdown products from blood cells impart ...Read more

It can be benign: Some people are prone to have a few RBCs in their urine. As long as your Bladder and Kidney are checked out to be healthy and free from any tumor or growth, then you can ignore it. I would suggest that you get your kidneys checked out with a CT scan of the abdomen to be sure that there is no tumor there. ...Read more

Causes of hematuria: Hematuria can be caused by any bleeding in the urinary tract. It could be caused by a tumor of the kidney, kidney stones in the ureters or by a bladder tumor, among other things. Have your urine cultured and if you have hematuria with no uti, see a urologist for evaluation. If you do have an uti, have your urine analyzed after the infection to make sure it resolves. If not, see a urologist. ...Read more

Asymptomatic Microscopic hematuria in urine at least 2yrs. No protein Urologist did cystoscopy. Nothing. Said idiopathic. Causes? Please be specific.

Microscopic hematuria: It could be a benign condition, Ig A nephropathy or thin basement membrane disease.
Make sure bp is normal and kidney function is stable.

Other reasons could be other glomerulonephritides, but they usually give rise to protein in the urine. Some people have kidney cysts or small kidney stones but they also give rise to frank blood in urine. ...Read more

If normal morphology for red cells can a renal cause be eliminated for a microscopic hematuria in urine?ct scan normal no infection.

If normal morphology for red cells can a renal cause be eliminated for a microscopic hematuria in urine?ct scan normal no infection.

See a Urologist: CT with contrast is good to find small renal masses. Really tiny ones not on CTs can still cause hematuria, but are often not clinically significant, at least not yet. A follow up CT sometime may be considered.
Blood may be from the ureter or bladder, requiring CT/U/S or poss. MRI.
Blood can come from diffuse renal disease, esp. if there is also protein in the urine. CT may not see this. ...Read more

26 f, microscopic hematuria detected inconsistently in urine tests. Blood tests show kidney function is fine. Should i be worried/see a urologist?

Constant hematuria: If you have no urinary tract infection, you need go to a urologist to assess your urinary tract. You will need a renal ultrasound and probably an intravenous pyelogram to see if there are any problems with your kidneys. If these studies show no problem, you will need to have the urologist do a cystoscopy so your urinary bladder's wall can be visualized to see if you have any abnormalities there. ...Read more

I have both microscopic hematuria and mucus present in my urine. I am a 30 year-old female and terrified I have urachal cancer. How likely is this?

Urachal cancer: I've only seen a handful of urachal cancers in the last 20 years. It would be very unlikely. Speak with your urologist. You may need to have an examination of your bladder with a cystoscope. Best of luck. ...Read more

Microscopic hematuria and cysto, bloodwork and ultrasound were fine. Malb/cre ratio was 156. I know that is high. Next steps are?

Microscopic hematuria and cysto, bloodwork and ultrasound were fine. Malb/cre ratio was 156.  I know that is high.  Next steps are?

Microalbumin High: Blood in the urine most commonly arises in the setting of bleeding within the urinary system. However, sometimes blood can be in the urine because the kidney isn't filtering as it should, allowing the blood cells into the urine.
Since your microalb/creat ratio is elevated, that could be a sign that the kidneys are leaking protein (not filtering well). You should see a nephrologist for evaluation. ...Read more
