Is urine routine normal pyelonephritis possible?

summary

Urine is the normal excretion of human body, we slowly found that such symptoms are caused by more than some differences, adults daily excretion of urine 1000 ~ 3000ml, children 3 ~ 4ml / kg per hour. The normal urine should be yellow or light yellow, clear and transparent, and the pH of fresh urine is weak acid. So, in life, we should pay attention to it, the following talk about urine routine normal pyelonephritis possible?.

Is urine routine normal pyelonephritis possible?

First: first, look at the urine pH, normal urine, generally neutral or weak acid, now the checklist, each item generally has a normal reference value, morning urine pH 5.5 ~ 6.5, random urine pH 4.5 ~ 8.0. Generally speaking, the increase of urine pH is respiratory alkalosis, hyperkalemia, infectious cystitis, long-term vomiting, oxalate and phosphate calculus, renal tubular acidosis or the application of some basic drugs. The decrease of urine pH is generally respiratory acidosis, diabetic ketoacidosis, gout, urate and cystine stones, urinary tuberculosis, nephritis, anokalemic metabolic alkalosis, severe diarrhea and starvation. The application of some acidic drugs will also lead to the decrease of urine pH.

Second: we look at the specific gravity of urine. The normal reference value is 1.015-1.025 for adult morning urine, 1.003-1.030 for adult random urine, 1.002-1.004 for newborn. The increased specific gravity of urine may be acute glomerulonephritis, heart failure, diabetes, proteinuria, dehydration, hyperthermia, shock, ascites, peripheral circulation failure, urinary obstruction, pregnancy induced hypertension syndrome. The decrease of urine specific gravity may be chronic nephritis, chronic renal insufficiency, chronic pyelonephritis, glomerular damage disease, polyuria of acute renal failure, polyuria of uremia, connective tissue disease, diabetes insipidus, protein malnutrition, malignant hypertension, hypocalcemia, and renal or primary, congenital or acquired renal tubular dysfunction.

Third: we look at the normal urine protein, urine test sheet will show negative. If the test results show positive, it may be ① functional proteinuria (severe exercise, cold, mental stress, more common in adolescents or pregnant women). ② Pathological proteinuria (mainly seen in acute and chronic glomerulonephritis, pyelonephritis, nephrotic syndrome, renal tumor, diabetic glomerulosclerosis, lupus nephritis, Henoch Schonlein purpura nephritis, renal arteriosclerosis, deep vein thrombosis, cardiac insufficiency, active pyelonephritis, interstitial nephritis, renal tubular acidosis, renal tubular heavy metals (mercury, lead Acute hemolysis, muscle injury, multiple myeloma, primary macroglobulinemia, severe skeletal muscle injury and large area myocardial infarction, cystitis, etc. in addition, some antibiotics, antifungal drugs, antineoplastic drugs and antipsychotics can also cause nephrotoxic proteinuria.

matters needing attention

What should be noted is not to be frightened by the diseases listed above, not to draw a conclusion easily based on only one result, and to make a comprehensive judgment according to the cause of the disease itself or the patient, combined with various data. Check the words to get up early in the first urine in the urine is the most accurate.
