In the treatment process of renal failure, the diagnosis of renal failure is very important. Through diagnosis, the development process of the patient's condition can be understood, and the corresponding treatment methods can be determined. So, what are the diagnostic tests for renal failure now? Let's give a detailed introduction below.
1. Urine examination allows patients to differentiate between pre renal ARF and renal parenchymal ARF through urine examination, thereby determining the patient's condition.
2. Blood biochemical examination, patients should pay attention to monitoring changes in electrolyte concentration, as well as blood creatinine and urea nitrogen.
3. Renal imaging examination can help patients with renal failure understand the size, morphology, blood vessels, ureters, and bladder obstruction of the kidney through abdominal plain films, ultrasound, CT, magnetic resonance imaging, etc. It can also understand renal blood flow, glomerular inflammatory response, and renal tubular function. The use of contrast media may worsen renal damage and should be used with caution.
Diagnosis and differentiation of renal failure
Generally speaking, when the patient's urine volume decreases sharply and renal function deteriorates sharply, the possibility of ARF should be considered. Once the diagnosis of ARF is confirmed, further differentiation should be made between pre renal, renal, or post renal ARF.
1. Diagnostic basis
1. Does the patient have a history of nocturia? The amount of nocturia exceeds the average during the day, indicating dysfunction of distal renal tubular concentration. Patients with a history of this disease are mostly CRF.
2. Does the patient experience anemia? Almost all CRF patients have anemia, and glomerular and renal vascular ARF patients also have anemia, while renal tubular and renal interstitial ARF patients mostly have no anemia or only mild anemia. Therefore, renal failure without anemia often indicates renal tubular or renal interstitial ARF.
The above introduces the diagnostic tests for renal failure. After confirming their condition, it is best for patients to regularly go to relevant hospitals for renal failure tests, which can help patients understand their condition,
