Urine output varies: How much you eat and drink has more to do with your volume of urine than your size. It's true a big guy who is 6'8" will make more urine than a little old lady who is 5'5", but there is not a direct correlation to size. Stay well hydrated, drink at least 64 oz of water and non-sugary beverages a day and your kidneys will thank you! ...Read more

Age 70, CKD (Cr 2.6). Is sudden fall of BP from 160/80 to 130/70 for 3 days with decreased urine volume a warning sign for CKD? Or it may just happen?

Age 70, CKD (Cr 2.6). Is sudden fall of BP from 160/80 to 130/70 for 3 days with decreased urine volume a warning sign for CKD? Or it may just happen?

Probably okay: Try to stay decently hydrated as your physician permits. Everyone's blood pressure fluctuates as does the urine volume. The sudden onset of acute renal failure will leave you feeling very sick. Be careful not to take meds that may shut your kidneys down temporarily (ibuprofen is infamous) unless you have your physician's permission first; otherwise sudden kidney failure is unlikely. ...Read more

My urine volume for uric acid testing was 6300 ml. Would that increase make a ua result of 1216 mg normal ? Do you adjust for volume ? Ty

My urine volume for uric acid testing was 6300 ml.  Would that increase make a ua result of 1216 mg normal ? Do you adjust for volume ? Ty

Not really: Making 6 liters of urine means you drank a whole lot, likely too much. That said, it should effect your uric acid excretion too much. I would repeat the test with a more normal 2-3 liter oral intake of fluids. You should also have your blood uric acid level checked, and you urine ph with a dipstick. ...Read more
