[|Human|] I had a7mm stone manually removed 5wks ago and a stent was placed in me.  The stent is still there.  I have had visible blood (varying from pink to merlot in color) every day since. I have made two trips to the Emergency room for clots blocking the catheter and once for aTIA caused by being off my coumadin for three weeks.  I am back on coumadin and still bleeding. I am also starting to pass small clots.  Is the clotting something to be concerned about especially in light of the TIA>
[|AI|]  Hi, It is possible that your doctors have put in place a DJ stent in the kidney to allow proper urinary Chat Doctor.  Double-J ureteral stents are commonly used to manage urinary obstructions. Pain, bladder irritation symptoms, and fever are usually signs of early complications related to double-J stents; late complications are more troublesome and can include bleeding as you are experiencing. When a stent is kept for a period of time, complications including migration, fragmentation, and encrustation and this can cause bleeding along with the fact that you are on treatment for TIA with Coumadin. You might have to consult your urologist to know if the stent has in any way migrated and caused mucosal injury in the ureter.
