Kidney stones: Nephrolithiasis, also known as kidney stones, is a disease affecting the urinary tract. Kidney stones are small, hard deposits made up of calcium, phosphate and other minerals/acid salts that stick together in concentrated urine. They are the common cause of blood in urine and can be painful when passing through the urinary tract. Symptoms include severe pain, usually in one side of the abdomen and nausea. 

Renal tubular acidosis: It is a condition that involves the accumulation of acid in the body due to the failure of the kidneys to acidify the urine appropriately. The kidneys fail to excrete acids into the urine, which causes the blood to remain too acidic. If not treated, it could lead to kidney stones, bone disease, kidney disease or failure.
