Acute renal failure without cure, a short period of time there is no death can also be a direct transition to chronic renal failure. The common reasons are described below: 1. Chronic glomerulonephritis progression to the late stage is the most common cause of chronic renal failure. 2. Interstitial nephritis (Interstitial Nephritis) is a group of mainly involving the renal interstitial and renal tubular disease, also known as tubulointerstitial nephropathy (Tubulo-Interstitia Nephropa-thy). Its complex causes, is a common clinical disease, accounting for Urinary system diseases of 25% to 33%, living in the second place of chronic renal failure.

Children with IgA nephropathy common examination: Common examination: urinary occult blood (BLD), urinary protein, circulating immune complex (CIC) First, urine test (1) hematuria: clinically about 40% to 45% of the patients showed gross or microscopic hematuria, 35% to 40% of patients with simple microscopic hematuria, or microscopic hematuria with a small amount of proteinuria. Naked eye hematuria can be sustained for several hours to several days, after the conversion to persistent microscopic hematuria, some patients can disappear, but often attack, the recurrence of nausea hematuria. (2) proteinuria: mild proteinuria, the general urine protein quantitative <1g / 24h, a small number of patients may be a large number of proteinuria and even nephrotic syndrome. 2, immunological examination (1) IgA increased: about 1/4 ~ l / 2 patients with elevated blood IgA, mainly increased the number of polymer IgA. (2) circulating immune complex: about 1/5 ~ 2/3 children with blo
