Kidney check, check what is the clinical significance of urine shape?

In the inspection of kidney, urine check is the renal pathology of the disease and to examine the effects of treatment of the most commonly used method, in the urine sample in the shape of a check is necessary, so the shape of the urine examination in clinical has what effect?Shandong weifang can double kidney disease hospital kidney disease experts explain in detail for you.
(1) the proportion of reflect the quality of the solute in unit volume of urine.The eduction in normal daily urine soluble solids volume is constant, the proportion is between 1.010 ~ 1.030.Proportion reflect the renal tubule and collecting duct of urine concentration and dilution function.In the early morning urine specific gravity is usually acuity 1.018 for the first time.Men and women over the age of 40, urine concentration function gradually reduce, increase 10 urine specific gravity by 0.00015 on average.Pathologic urine specific gravity lower in chronic renal damage, renal tubular concentration decreasing ability, diabetes insipidus, drinking lots of water and rehydration.CRF as the proportion of low and fixed.Diabetes, water shortage, such as vomiting, diarrhea and high fever sweating a lot of urine specific gravity dehydration state, normal renal enrichment function.
(2) normal urine bubble without bubbles.If the content of protein in the urine, the change due to surface tension, discharge of urine floating on the surface of a layer of tiny bubbles, these small bubble is not easy to disappear.To put proteinuria in vitro gently shake surface appear small bubble urine may also be seen.
(3) with ammonia smell urine smell, usually because of bacteria to produce ammonia and urea decomposition scent.E. coli infection in urine smell of corruption, ketonuria fruit aroma, a variety of metabolic disease can produce special smell.
(4) color normal urine from colorless to deep amber color change is bigger, depends on the urine of pigment concentration and urine ph value.Cause abnormal urine color many, in addition to food and drug can affect the color of urine, some disease often can make the urine color change, therefore, urine color can often provide clues for clinical diagnosis, such as chyluria, porphyrin urine, blackwater, etc.But clinically important be hematuria, hemoglobinuria or myoglobinuria between the identification, and to distinguish with other cause of red urine, benzidine test, test, was the commonly used o-toluidine test and microscopic examination of the urine red blood cells to differentiate hematuria, hemoglobinuria or myoglobinuria.

(5) the turbidity when urine is more clear, more cloudy after placement.Cold can make the urine mineral salt crystallization precipitation, alkaline urine easily appear phosphate precipitation, acid urinary uric acid salt precipitation is seen.Turbid urine can be caused by bacterial growth.Can itself can also be used by bacteria by bacteria urease turn urea phosphate precipitation caused by turbid urine, but less common.In addition, the mild hematuria, chyluria, nephrotic syndrome when fat urine, epithelial cells (white pollution) can also cause urinary cloudy.
