Staging of diabetic renal failure? How to find what symptoms?By kidney specialists on this issue to explain, the diagnosis of diabetic nephropathy, the exclusion of other causes of intermittent or persistent clinical proteinuria (urinary protein), this is the key to the diagnosis of clinical DN ... Increased kidney size, glomerular filtration rate, expansion of the glomerular afferent arteriole, glomerular pressure ... staging of diabetic renal failure? How to find what symptoms? This problem can refer to the following:
Diabetic renal failure stage renal volume increases, the increase in glomerular filtration rate, glomerular afferent expansion, increased pressure within the glomerulus.
Two: thickening of the glomerular basement membrane, urinary albumin excretion rate in the normal range.
Three phases: early diabetic nephropathy, microalbuminuria.
(4) four: clinical nephropathy, urinary protein gradually increased glomerular filtration rate, may be associated with edema and hypertension, renal function gradually diminishes.
(5) five: uremia, the majority of renal units atresia, urinary albumin excretion rate decreased, serum creatinine, blood urea nitrogen, increased blood pressure.
The kidney has a strong reserve capacity, 25% to 50% of renal function only with normal renal function, usually the patient may still renal failure symptoms. But at this time, such as marketing to increase its damage, the patient can quickly renal failure symptoms.
Early diabetic chronic renal failure, in addition to serum creatinine increased, often without clinical symptoms, but only the basis of the symptoms of the disease to the progression of the disease to the residual renal unit can not be adjusted to adapt to the minimum requirements of the body, renal failure symptoms will gradually manifested. Uremia, the function of every organ system disorders and a variety of symptoms of uremia. Dialysis can improve most of the symptoms of uremia, but some symptoms, even heavier.
