My husband had radical surgery last May to remove a kidney, his bladder, prostate and associated lymph nodes. He then had follow up chemotherapy.  

He had a Ct in November which showed nothing unexpected. 

Since the end of November he has had issues with very raised potassium levels. His meds have been adjusted and it has decreased but still above normal.

Am I expecting too much wondering why there has been no further follow up, checks or communications. It's as though surgery is done and that's it. 

Will there be further scans or at least checks that his remaining kidney is OK etc.

Just feeling lost and frustrated
