Kidney stones need to be treated without pain. Kidney stone is a foreign body to kidney, it will make the urine flow from kidney to ureter not excreted properly, on the one hand, it will cause urinary tract infection, patients may have fever, frequent urination, urgency of urination and other symptoms, serious patients will have perinephric abscess or even sepsis, and the above symptoms will recur. On the other hand, kidney stones will get stuck on the ureter in the process of moving down and lead to hydronephrosis, after hydronephrosis, the renal cortex will be compressed, the renal cortex will become thinner and thinner, the function will be reduced, and the serious cases will lead to the complete loss of renal function of the hydronephrosis kidney, that is to say, kidney stones are not painful, which does not mean that the damage to the kidney is small, and invisible damages will all cause more serious consequences. Therefore, it is recommended to deal with kidney stones as early as possible, either by applying medication or by using surgical methods, so as to eliminate or minimize the invisible damage.
