Chronic renal failure leading to uremia can be little urine, can also be normal, or even increase. Whether or not the urine contains protein depends mainly on primary disease. Urine osmolality was low, urinary sodium concentration is 40 to 90 mEq / L, urinary urea concentration is usually 10 times the serum urea concentration below. Chronic renal failure enters the terminal stage with very little urine protein, little urine, or even no urine.

Changes of urine volume in uremic patients

Oliguria acute renal failure 24 hours urine volume less than 400m1, there may be a small amount of urine protein, urine osmolality is generally 280 to 300 mOsm / kg. Urine sodium content is often greater than 40 ml equivalent /l, the normal urine urea concentration is about 12~15 times of serum urea concentration, while uremia is only 2~3 times. In acute renal failure, the urine volume can reach 35L / day.
