Diagnosis and differential diagnosis of renal failure

2017-06-14 15:52

In the course of treatment of renal failure in the diagnosis of renal failure is very important, the development process can be learned through the diagnosis of the patient's condition, so as to determine the appropriate treatment, so now a diagnosis check which renal failure? Let's introduce in detail.

1 、 urine test, patients can be checked by urine to identify pre renal ARF and renal parenchymal ARF, thereby determining the patient's condition.

2, blood biochemical tests, patients should pay attention to monitoring changes in electrolyte concentrations and serum creatinine and urea nitrogen.

Check 3, renal imaging for renal failure patients by using abdominal X-ray, ultrasound, CT, MRI examination is helpful to understand the renal size, morphology, blood vessels and ureter, bladder obstruction, renal blood flow, also can understand the effect of nephritis and renal tubular ball function, the use of contrast agent may aggravate renal damage, should be used.

Diagnosis and differential diagnosis of renal failure

Generally speaking, when the patient's urine volume drops sharply and the renal function deteriorates rapidly, the possibility of ARF should be considered, and the ARF diagnosis should be further identified whether it is anterior, renal or post renal ARF.

1 、 diagnosis basis

1, patients with nocturia disease? Night urine volume over the day, suggesting that distal renal tubule dysfunction, the disease history of more than CRF.

2, whether patients with anemia? CRF almost have anemia, glomerular and renal vascular ARF also anemia, renal tubular and interstitial renal ARF were anemia or only mild anemia, so without anemia of kidney failure, more suggestive of renal tubular or renal interstitial ARF.
