The ureter is blocked, because the ureter itself has a small lumen diameter, especially three narrow places, which means that once there are stones, blood clots and necrotic tissue in the ureter, it is easy to cause ureteral blockage.

Ureteral obstruction caused by ureteral stones is mainly manifested by the symptoms of ureteral stones themselves. The size of the stones is not necessarily proportional to the degree of obstruction, hematuria, and pain. In the ureter and in the upper part of the stone, the incarcerated blockage or stones in the downward movement process often causes the typical ipsilateral renal colic and microscopic hematuria. Pain can radiate to the inner thighs, testicles, or labia. Often accompanied by nausea and vomiting, sometimes hematuria is visible to the naked eye. In larger stones that do not affect the flow of urine, there is only faint pain and light hematuria.

The main characteristics of ureteral obstruction caused by blood clots in the ureter are: hematuria and ureteral filling defect are similar to ureteroma, but the ureteral blood clot is volatile. Two angiographic examinations at different times can reveal changes in its position, size and morphology.

Ureteral obstruction is likely to cause a variety of complications. The most common is hydronephrosis, which is most likely to cause kidney damage if left untreated. Other hazards are concomitant hazards caused by the cause of ureteral obstruction.
