When 6mm stones are expelled from the body with urine, most patients can experience foreign body sensation or pain, and a few patients have no obvious sensation.
6mm stone size is relatively large, generally not easy to discharge directly from the urethra, even if it can be discharged with the urine, in most cases, the patient can feel the obvious foreign body sensation. Moreover, the shape of the stone varies, and some sharp stones may scratch the mucous membrane of the urethra when passing through the ureter, resulting in pain, hematuria and other symptoms.
There are individual differences between different patients, and clinically there are also a few patients who have no obvious self-conscious symptoms or feelings after discharging 6mm stones. It is important to note that 6mm stones are usually difficult to expel normally and are prone to form urinary tract obstruction.
Once the diagnosis of stone disease is confirmed, it is recommended to follow the guidance of a specialist for treatment.
