My family has kidney disease history. My brother and sister expired due to renal failure. I also had renal failure 5 years ago after delivery of my son then i got renal transplant but now it has also stopped functioning. Biopsy report show global glomerulosclrosis. But the actual reason of kidney failure is still unknown. my doctor said Perhaps it might be due to primary hyperoxaluria but the oxalate level in my blood is in its normal range according to oxalate test in blood. Kindly help me in this regard. I havr no family member which can donate his kidney. Then what will be final solution for me.
