My daughter had a kidney stone removed on Thursday, March 12th. They were going to remove the stone but ended up blasting it and put in a stent that she is to where until this Thursday, March 19th. She was sent home on day of surgery and she had large clots that she passed the first 24 hours or so. She called and they said if they were larger then a quarter and continued to come to ER. The clotting has stopped but not the discomfort and blood in the urine. She is still taking pain medication but has had this surgery before and these symptoms this time are not the same. The doctor office has not returned her calls. Do you think that maybe she could have a kidney infection or what other problems can there be? SHe is in Arizona and has had all other procedures at Mayo Clinic in Rochester MN.
