Ureteral stones can cause abdominal distension. When ureteral stones cause complete obstruction of the urinary tract, the pressure in the lumen of the ureter increases sharply, causing acute local expansion of the ureteral wall, spasm and ischemia, hypoxia, and the acute expansion of the ureter causes expansion of the renal pelvis, resulting in hydronephrosis and renal colic. Since the ureter and the intestine have common innervation, gastrointestinal symptoms such as abdominal distension, nausea, vomiting, etc. can only be relieved if the obstruction of ureteral stones is removed early. Depending on the size and location of the stone, medication, extracorporeal shock wave lithotripsy, ureteroscopic lithotripsy, and percutaneous nephrolithotripsy can be chosen.
