Children with acute renal failure check

Image Diagnosis:
    1.B Ultrasonic inspection : kidney size can be observed , while the presence or absence of kidney stones and tips hydronephrosis . If examination showed normal kidney size , there are obvious hydronephrosis, strongly suggestive post-renal causes.
    2 Abdominal x -ray : kidney size for observation , while positive stones can be found .
    Blood: Common hemoglobin and red blood cells decreased slightly , there is a secondary infection often have leukocytosis and left shift , the individual may have thrombocytopenia .
    Blood biochemical measurements : oliguria most significant change . Common blood urea nitrogen , creatinine significantly increased, decreased bicarbonate . There may be a variety of electrolyte imbalance in potassium and low in sodium is the most common , but also can occur in low calcium and high phosphorus. Early polyuria also many significant metabolic acidosis and azotemia , often have abnormal blood electrolytes , especially potassium -prone or high sodium.
    Urine: common and specific gravity to reduce proteinuria . Sediment examination shows red blood cells, white blood cells and casts. If due to prerenal factors , early often high specific gravity , urine sediment examination and urine protein found no abnormality ; renal factors can affect even those who often have significant proteinuria and microscopic sediment anomaly .
    Renal biopsy : indications of renal causes of acute renal failure, can understand the pathological type and extent of kidney disease , contribute to the development of treatment programs and prognosis .
