How painful are urinary stones?

How painful is urinary calculi? How many grades can they reach? Urinary calculi cause pain symptoms, the most serious of which is ureteral calculi. Because ureteral calculi cause acute obstruction of the ureter, the pressure in the renal pelvis increases significantly in a short period of time, thus stimulating pain nerves and causing severe pain. This pain is like colic, so it is called renal colic. The degree of renal colic is usually very severe. It can be said that if the highest score of pain is 100, he can reach 90 or even 95. Therefore, if this kind of renal colic is displayed, we need emergency pain relief treatment. After the pain is relieved, we will treat the stones.
