I have not heard nor read about PSA elevation being a side effect of BCG. From what little I remember from my docs, it is somewhat normal as men age to have a slow increase in the PSA number. 1.68 to a 5 is a quick increase. Also, from what I remember (I haven't really discussed these with them in 3-4 years, 65-70 year olds have readings from what I recall is at 4.5 to 6.0) a 6 is border elevated but, your numbers appear to have stabilized. At the same time, none of us are doctors so I'd ask for clarification next time you meet. The pelvic MRI sounds reasonable to me.
