My husband has a sacrum chordoma. It has metastisized to the liver, lungs, bone and blood. Hus urine is continually dark, cloudy, foamy, and white flurry things in it. He is on hospice care and they provide him with antibiotics for 14 days. 3 or 4 days after the antibiotics are finished the symptoms repeat. They have not given us a time frame but he is pretty much bed ridden. Are these urine infections a sign his kidneys are failing?
