I'm 68yrs old with severe scarring of uterus. waiting for mri. have total blockage above cervix. d&c and biopsy couldn't get through. do i have to worry about the scarring affecting other organs?

Probably not, though it would be useful to know the indication for a D&C and now an MRI. Cervical scarring and blockage is not that unusual in women who are many years postmenopausal, due to normal atrophic changes from low estrogen levels, and since D&C's are not routinely needed in this group most affected women will not be aware of this.
