What are renal calculi?

Kidney transplantation is the ultimate method in the correction of acute renal failures (kidney failure). A functioning kidney is used in transplantation from a donor, preferably a close relative, to minimise its chances of rejection by the immune system of the host. Modern clinical procedures have increased the success rate of such a complicated technique. Renal calculi: Stone or insoluble mass of crystallised salts (oxalates, etc.) formed within the kidney. Glomerulonephritis: Inflammation of glomeruli of kidney.
