Causes of urea increase and decrease in urine

Last reviewed: 23.04.2024
Reduction of urinary excretion in urine takes place during growth, during pregnancy, with a small number of proteins in the diet.
In clinical practice, the determination of urea in urine is used to monitor the state of the processes of anabolism and catabolism in the body. This is of great importance, especially for resuscitation patients in a serious condition receiving enteric (parenteral) and parenteral nutrition. Having determined which processes prevail in the patient (increased urea excretion in the urine indicates a negative nitrogen balance, a lower-positive one), one can calculate the amount of protein preparations necessary for the patient.
Positive nitrous balance occurs in liver diseases accompanied by a decrease in urea formation; with violations of kidney function (simultaneous increase in the concentration of urea in the blood); Admission of hormones with anabolic effects (growth hormone, testosterone, insulin, etc.).
Negative nitrogen balance is revealed in patients in the postoperative period, with hyperthyroidism.
