Blockage: Kidney ultrasounds evaluate blood flow into the kidney and urine flow out of the kidney. Often, kidney function can be preserved long after blood flow or urine output begins to deteriorate. Also ultrasounds can pick up cysts and tumors that blood tests don't. ...Read more

Sonogram (Definition)

The sonogram is a test that looks at body organs with no radiation. It uses sound waves and can give us a 2 dimensional view of organs such as the kidney, liver, heart, and lungs. It can define spaces that are either solid or full of fluid. I can also guide large needles into an organ or near the spine, and can help define the area being cut open. Its a ...Read more

I had 3 blood test for serum cheatinine last one was 2.1.  Had ultrasound. Dr. Sent me letter 6 months ago kidneys look good. Should I be concerned?

Yes: Serum creatinine correlates with msucle mass and above 1.6 mg/dl is abnormal for even a muscular man, unless he's elderly at which time some loss of kidney functions is expected. I'm glad you are being followed; we can be confident you have some mild kidney damage, but this happens to all of us as we age. ...Read more

30 yr old female. Had renal ultrasound for micro hematuria. Left ureter jet wasn't firing. Kidney blood test normal. Could this be cancer?

30 yr old female. Had renal ultrasound for micro hematuria. Left ureter jet wasn't firing. Kidney blood test normal. Could this be cancer?

Blood in urine: It is not likely that you have a cancer. I see you are taking anticoagulant meds. This can predispose to hematuria. Given the ultrasound finging of what could be slowed urine passage thru one ureter, coupled to microhematuria, I recommend further dialogue with your docs. An IVP or better, a CT-IVP is a valuable next test. ...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?

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. ...Read more

More work-up needed: Any medical test needs interpretation together with a patient's history, examination and imaging. Abnormal blood tests for kidney function suggest a need for further explanation of why. Reasons may include problems before blood flow gets to the kidneys (like narrowed arteries), problems with the kidneys (kidney disease) or after the kidneys (like prostate enlargement). Don't panic, get evaluated. ...Read more
