If a 5mm kidney stone falls into the ureter, it takes almost 2-4 days for it to be completely expelled. The development of kidney stones is related to the patient’s daily life and eating habits, and is seen in people who drink little water, exercise little, and like to eat foods high in calcium oxalate. The urological ultrasound is able to analyze and diagnose kidney stone lesions, and for smaller kidney stones, they can be discharged by themselves. The current stone diameter is 5 mm, which is relatively small and can be expelled by itself. However, the premise of discharge requires the stone to detach from the kidney calyx and fall into the ureter before it can fall from the ureter into the bladder and finally be discharged through the urethra, and the time from the stone entering the ureter to complete discharge is almost 2-4 days. In the process of stone activity, patients may have symptoms such as abdominal pain and hematuria in the naked eye. At this time, patients need to drink more water and do some jumping movements to promote stone discharge. In addition, after the stone is discharged, patients need to adjust their daily living habits, regular work and rest, and healthy diet to reduce the chance of stone recurrence.
