Ureteral obstruction can be painful because it blocks the flow of urine and can ultimately affect the kidneys.
Sometimes the blockage is so severe that interventional radiologists are brought in to relieve the emergency condition. In these cases, patients have to undergo two separate invasive procedures, according to BrightWater Medical, a medical device company that wants to bring relief to these patients. The Mountain View, CA, startup is developing the means by which the need for the second procedure can be removed altogether.
