Good morning @mariags 😊
When I had my kidney transplant, the stent caused blood in my urine too. It's very, very common (and scary!).
I think most kidney transplant patients will agree they had that "red to pink" experience with their urine bag too.
Remember, just a few tiny drops of blood from the irritation of the tube or stent (and the placement procedure) can cause the drops of blood to look like a huge amount in the bag....I was very scared too, but my nurse explained that it was just a tiny amount of blood turning the bag pink and it will improve. My urine bag stayed pink until the catheter was removed three days later. (My nurse kept reminding me not to worry).
Please remind your son to stay hydrated and sip liquids throughout the day. It's important to keep things flushed, keep his kidney happy and help with the healing process from the procedure. He shouldn't overdo the hydration, but an 8oz glass every hour for eight hours is probably a good rule.
(Also, not to overdo his physical activity. No soccer games today). Normal activity is fine if the doctor said it was okay?
If your son stays well-hydrated, the bag should turn from red to pink by tonight.
"Pink" just means a few drops of blood from the irritation and is nothing to worry about. The "red" is normally caused by the initial trauma of the procedure and normally calms down in 24 to 48 hours as it heals.
I am happy the nurse will be there to double-check everything, flush the bag, and assure that everything is normal.
Please keep me posted today or tonight when the bag color improves and turns from red to dark "pink".
Maybe set your phone or watch alarm and hand your son a nice drink of water each hour to help flush his "plumbing system" ....and the bag will be pink soon! 😊
Sending love and BIG hugs to your son, you and your husband. Keep me posted on the progress! All will be well, you will see.
