Extracorporeal shock wave lithotripsy is generally not more than four times, ureteral stone crushed more than four times stone size, location did not change, it is recommended that ureteroscopy lithotripsy, multiple extracorporeal lithotripsy may cause ureteral scar formation, or lead to ureteral rupture, stenosis and so on.
1. Ureteral scar formation: If there are many times of lithotripsy in the ureter, it may cause the ureter to stiffen and eventually ureteral scar will be formed.
2. Ureteral rupture: If you do not pay attention to the way and method during the operation, or the vibration adjustment is too large, it may affect the internal circulation, which may lead to the rupture of the ureter.
3. Ureteral stenosis: some patients may have ureteral stenosis after ureteral sonic lithotripsy, which may affect the normal discharge of urine.
If multiple lithotripsy is needed, it should be done under the guidance of experienced physicians to avoid damage or other complications due to improper operation or for other reasons. Regular observation should be made after lithotripsy, and medical attention should be sought in case of any adverse reaction or symptoms such as hematuria or pain.
