Ureteral stones

Most of the ureteral stones originate from the kidney, and most of them are unilateral stones, which mostly occur in middle-aged men. They are higher in men than women. Stones are commonly found in the following areas: ① the pelvic ureteral junction; ② the ureter spans the iliac vessels; ③ the female ureter passes through the base of the broad ligament of the uterus and the male vas deferens crosses the ureter; ④ the bladder wall section of the ureter includes the bladder opening. The main secondary lesions include urinary tract obstruction, infection and epithelial damage, canceration, etc. Large or rough stones, which can easily become embedded in ureteral stenosis and cause severe obstruction, renal impairment, severe bilateral ureteral stones and even kidney Functional failure.
