transient proteinuria
Introduction
Introduction Temporary or transient urine protein refers to normal kidney, but transient urine protein occurs during fever, heart failure or dehydration. After exercise, there may be an increase in temporary urinary protein excretion, especially after adolescent long-distance running, swimming, football, basketball and other sports, the protein in the urine is transiently increased.
Cause
Cause
When the patient has dehydration, fever, too cold weather, intense exercise, taking painkillers, or high fever, acute illness, pregnancy, high blood pressure, etc., transient proteinuria may occur.
It usually lasts for several hours and generally does not exceed 24 hours. After the urinary protein is removed from the original cause, the protein in the urine can be turned negative, and the protein rarely exceeds (++), but when the urine is concentrated and the specific gravity of the urine is 1.030, the protein quantification can be higher.
The normal adult daily urine protein quantification can be up to 150mg. If the drinking water is very small, the urine is too concentrated, and the urine volume is also reduced, the amount of protein contained in the unit volume is more, so normal people can also have urine protein. On the contrary, drinking too much water, the urine is diluted, even if the original urine protein is positive, it can be turned negative.

Urine routine urine protein quantification
Examination of the diagnosis of transient urine protein:
If the urine is collected once to check the urine protein, its clinical significance is not significant, even if the result is positive, it can not be diagnosed as kidney disease. However, it is much more accurate to check for morning urine and to exclude orthostatic proteinuria. As long as the amount of drinking water after dinner, the first morning urine urine protein positive suggest that there may be kidney disease, but the diagnosis still depends on 24-hour urine protein quantitative examination.
Diagnosis
Differential diagnosis
Differential diagnosis:
(1) Postural proteinuria: closely related to the change in the position of the patient's body. Postural proteinuria is often found in young people. In general, patients lack protein in the morning, but after a long period of activity, walking, strenuous exercise, standing, or flexion, proteinuria will appear. When the patient is lying down, the measurement will disappear. In general, patients younger than 30 years old, urine protein is less than 2 grams per day, and Ccr (creatinine clearance rate) is normal, as long as regular blood pressure is measured and tracked annually; if it is greater than 30 years old, regular blood pressure is required, every six Check urine and kidney function for months.
(2) Intermittent proteinuria: Repeated infection of cystitis, pyelonephritis, urine protein, once the infection is controlled, proteinuria will disappear; and high blood pressure, heart failure and other diseases will appear intermittently with the disease Sexual urine eggs.
(3) Persistent (pathological) proteinuria: Usually when the kidney spheroid or tubular irreversible damage occurs, there will be persistent proteinuria. Glomerular disease is the most common cause of pathological proteinuria.
(4) Obesity: If the patient is overweight, overweight will increase the kidney load and will cause proteinuria.
It usually lasts for several hours and generally does not exceed 24 hours. After the urinary protein is removed from the original cause, the protein in the urine can be turned negative, and the protein rarely exceeds (++), but when the urine is concentrated and the specific gravity of the urine is 1.030, the protein quantification can be higher.
