Ureteral stone expulsion time is related to the size of the stone, for stones smaller than 1mm it may take 1-2 days to expel from the body. Stones entering the ureter need to pass through three physiological strictures of the ureter. If the stone is less than 1mm, it is able to pass through the end of the ureter into the bladder and can usually be expelled through urination in 1-2 days. During stone removal, the patient may experience pain in the urethra, followed by the appearance of hematuria in the naked eye and the ability to find a grit-like substance in the urine. If the stone is large and embedded in the three physiological strictures of the ureter, it cannot be expelled. At this time, it may also induce the problems of ureteral effusion and hydronephrosis, which should be considered to be handled by surgery. The stone can be crushed and expelled through minimally invasive surgical instruments such as cystoscopy and ureteroscopy, and it can usually be expelled on the same day after surgery. In addition, patients must drink more water during the process of stone expulsion to use urine to expel the stones, and pay attention to the adjustment of living and eating habits after expulsion to reduce the chance of stone recurrence.
