Is anyone on carfilzomib>

I have been on carfilzomib, dex, lenalidomide and Daratumumab for five cycles. Both carilzomib and lenalidomide can caus blood in urine. I have had this issue come up and the doctors who prescribed the cancer drugs don't think the drugs are causing the problem. Now I am going to have to do a cytoscopy for the bleeding. Just wondering if anyone has had blood in their urine from the cancer drugs. Thanks.
