They arise because substances in the urine are no longer sufficiently dissolved and are therefore too small Put conglomerates together. Depending on their size, they can no longer pass through the urinary drainage system from the kidneys via the ureters and the bladder to the urethra and get stuck. The kidneys or ureters try to transport the stone further and this sometimes causes very severe pain.
