An 8 mm kidney stone may fall into the ureter and may get stuck at the end of the ureter when it is discharged downward, requiring lithotripsy treatment, but when it is not able to be discharged on its own, lithotripsy treatment is required.
Under normal circumstances, 8 mm kidney stone may fall to the ureter, but due to the narrow end of the ureter, it may get stuck at the end of the ureter when discharging downward, and cannot be discharged on its own, which can cause symptoms such as severe lower back pain, frequent urination, hematuria, and even hydronephrosis in severe cases.
For 8 mm kidney stones, when stuck at the end of the mid-ureter, extracorporeal shock wave lithotripsy should be considered to break up the stone. If lithotripsy is not effective, surgical removal of the stone, such as ureteral flexible lithotripsy, should also be considered.
During the treatment process, it is important to actively cooperate with the doctor for treatment and not to handle it on your own.
