Second chance?

A few months after using my PD cath on a cucler machine the fluild backed into my thoracic cavity and had to be removed by thoracentsis and I went on hemo. That has been 10 months ago. I would like to try again but the doc is not thinking it will be good. Im saying this time Iam not so sick and can learn the propper way to do it. Gefore I was in the hospital due to a staff MRSA inf. in the spine from the perma cath and no one seemed to sure what they were doing. Has any one had this happen and was succesful at a second try…or not?
