In the process of kidney stone discharge, there will be increased urinary tract irritation symptoms, such as sudden appearance of frequent urination, urinary urgency, or with a significant sense of incomplete urination, abdominal pain progressively aggravated, then the stone may be discharged from the body at this time. Once the stone is discharged from the ureter into the bladder, the obstruction is lifted and the above symptoms can be relieved or disappear immediately. This is because the stone is discharged and the urinary tract regains its patency, so the urine is discharged smoothly into the bladder without obstruction, so the pain will be relieved immediately or disappear immediately. There are also the disappearance of the symptoms associated with kidney stones, such as nausea and vomiting that existed before, which will be relieved or disappear immediately after the stone is discharged, and the patient will not have any gastrointestinal spasms, or the disappearance of visual hematuria that existed before after the stone is discharged, which are all possible manifestations of kidney stone discharge.
