Renal insufficiency is categorized into acute renal insufficiency and chronic renal insufficiency according to disease progression. The diagnostic criteria of renal insufficiency are mainly based on the renal function and urine output etc.
1. Acute renal insufficiency: it is a rapid decline in renal function due to various reasons, manifested by a decrease in glomerular filtration rate and accompanied by an increase in blood urea nitrogen and blood creatinine. The glomerular filtration rate decreases in a short period of time, and the patient may have the symptom of decreased urine output or anuria.
2. Chronic renal insufficiency: chronic renal insufficiency often has a history of kidney disease, and the main clinical manifestations are hematuria, proteinuria, edema, hypertension and so on. Laboratory examination of urine sediment with red blood cells and tubular pattern, blood creatinine and urea nitrogen rise, glomerular filtration rate decline.
Patients with renal insufficiency should go to the hospital in time and be treated under the guidance of professional physicians.
