The pain of kidney stones in pregnant women needs to be relieved by drug treatment and stent placement. Pain caused by kidney stones after pregnancy is mostly due to stones falling into the ureter. First of all, we need to use pain relieving drugs, and at the same time, we need to use stone removing drugs, such as Lysimachia christinae granules. If necessary, a stent tube is inserted into the ureter under anesthesia to play the role of drainage, improve renal colic and avoid ureteral obstruction. If the stent tube is successfully pushed in, laser lithotripsy can be performed after delivery, so that the stones can be broken, which is conducive to stone drainage. Drinking more warm water at ordinary times can reduce the concentration of crystalline substances in urine, so as to avoid aggravating the condition of stones.
