My mother with MM recently had a catheter surgically placed into her stomach so she can do dialysis in her sleep, and the chemo is only getting rid of 70% of the cancerous cells. 70% might seem good, and her doctors think so, but it certainly isn't enough if she needs dialysis in her sleep. Thus, in her situation, it seems chemo is making things worse.

Has anyone else here had a catheter tube surgically placed for MM's renal side-effects? Is this common among MM patients?
