Emergency extracorporeal shock wave lithotripsy (ESWL) treatment for ureteral stones caused by renal colic: In 1160 cases, strong ghd plates, cystoscopy, and built-in ureteral catheters were used to gently move the stones up and down to loosen them, allowing the stones to break open and facilitating their discharge. Pelvic urine can be exported, reducing pressure within the renal pelvis and relieving pain. For larger stones, emergency ureteroscopic lithotripsy can also be considered for lower ureteral stones.
Since 2007, after ESWL combined with calcium antagonists and alpha-blockers (terazosin, later renamed alfuzosin), the effect of promoting stone expulsion has been significant. The mechanism is related to the distribution of receptors in the distal smooth muscle of the ureter and requires further study. ESWL is a minimally invasive treatment; in all cases, there were no serious complications. Treatment failure did not induce aggravation or progression of pre-existing concurrent diseases. Slight hematuria after treatment may disappear within 24 hours, local skin ecchymosis and pain are minor and subside within a week, not affecting daily activities.
In this study, acute renal colic and increased renal pelvic pressure are conducive to graveling the stones, which can effectively relieve pain. Emergency ESWL is worth promoting.
