Can you explain if it's possible for my kidney stone to be stuck ?

Here is...: Urinary stones are usually formed at the papilla of calyx where urine sipping out of the kidneys into its hollow part, called pyelocalyceal system. Such a stone may stay or detach from papilla over time while growing. If staying there, patient has no discomfort or pain; it detached, it may move out of calyx into renal pelvis, and then into ureter, where it may be stuck...
