Differential diagnosis should be made with the following symptoms:
The pathological state of partial or total loss of renal function in renal failure (1). Divided into acute and chronic two kinds according to their acute onset.
Acute renal failure due to a variety of diseases resulting in two kidneys in a short period of time, loss of excretory function. Acute renal failure. For less urine (urine or urine (<400mL/d) urine volume <50mL/d), electrolyte and acid-base imbalance and sudden uremia, also has a non oliguria type (urine volume >1000mL/d). Timely and appropriate treatment, renal function can be restored. Complex, critically ill patients, or not treated at the time can be converted to chronic renal insufficiency or death. Acute renal failure consists of the following 3 conditions: pre renal interstitial nephropathy. Due to the lack of blood volume or heart failure caused by insufficient blood perfusion, glomerular filtration rate decreased. Post renal interstitial nephropathy. Urinary tract and blood urea nitrogen (Bun) increased due to acute obstruction of urinary tract due to calculus, tumor or prostatic hypertrophy. Acute renal failure, arf. Due to renal parenchymal disease, in severe acute glomerular disease, acute interstitial diseases, acute tubular necrosis and acute renal vascular disease and chronic kidney disease, in some incentives under the action of the two acute deterioration of renal function, with the most common acute renal tubular necrosis.
2 renal failure renal failure can be pided into acute and chronic, acute renal failure disease progress rapidly, usually due to insufficient supply of renal blood flow (such as trauma or burn), renal obstruction caused by dysfunction due to certain factors or by poison damage caused by acute renal failure. Chronic renal failure is the main cause of long-term renal disease, with the time and the disease, the gradual decline in renal function, resulting in the occurrence of renal failure.
A history of chronic kidney, the kidney outside each organ system dysfunction, laboratory examination showed metabolites in blood accumulation, a series of electrolyte disorder, acid-base balance disorders, endocrine disorders, can establish the diagnosis. To establish the diagnosis of uremia, we should further clarify the cause of uremia. Are there any factors that may affect the deterioration of renal function, such as urinary tract obstruction, infection, dehydration, heart failure, the use of kidney injury drugs, surgery, anesthesia, shock, and the recent re - activation of the primary disease. B ultrasound and CT examination should show double kidney atrophy.
