If a female patient’s kidney stone is discharged, the most common feeling is that the severe renal colic suddenly does not hurt, because after the stone falls into the ureter, it will cause ureteral spasm, which will cause more serious renal colic. As the stone goes down, the symptoms of renal colic are changing, from the initial pain in the upper part of the kidney to pain in the lower abdomen, accompanied by pain in the perineum, if it suddenly disappears, it suggests that the stone may be discharged. There is a special case that the stone is stuck to the end of the ureter and cannot be discharged, in this case the stone is no longer in motion and there is no more obvious renal colic, which is easy for patients to ignore, leading to gradual aggravation of hydronephrosis and even damage to kidney function. So even if the renal colic disappears, you should go to the hospital for an examination to determine whether the stone is really discharged.
