My father 73 just had today an angioplasty with 2 stints.  Hes staying overnight at the hospital and theyve installed a catheter. the bag has bright red blood  a lot.  the nurses on staff say this is normal and the dr. will only be in another 12 hrs from now. 12 pm.  what is happening?  People i know who have had a catheter says this did now happen to them.   also its very painful when when he feels hes urinating.
Howell come to ChatDoctorI really appreciate your concern, if this is the urinary catheter you are talking about and the urine is red then it needs to be ruled out for hematuria some time it may be due to trauma that might have done at the time of insertion of catheter I would advise you to discuss this with the doctor instead of listing to others hope this information helps.
