What to do if a stone blocks the ureter

Ureteral stones are a disease that can easily cause urinary system diseases in patients. If stones appear in the ureter, it will cause inconvenience to the patient and severe pain during urination.

1. Stones blocking the ureter. Ureteral obstruction caused by ureteral stones is mainly manifested by the symptoms of the ureteral stones themselves. The size of the stone is not necessarily proportional to the degree of obstruction, hematuria, and pain. Stone impaction and blockage in the middle and upper parts of the ureter or stone migration downward often cause typical renal colic and microscopic hematuria on the affected side. The pain may radiate to the inner thigh, testicles, or labia. It is often accompanied by nausea and vomiting, and sometimes hematuria is visible to the naked eye. For larger stones that do not affect urine flow, there may only be dull pain and mild hematuria. The main characteristics of ureteral obstruction caused by blood clots in the ureter are: hematuria and filling defects in the ureter, which are similar to ureteroma. However, ureteral blood clots are changeable. Two angiography examinations at different times can reveal changes in their position, size and shape.
