I recently found out I have a floating right kidney. I have had 2 separate ultrasounds for 2 separate issues. My right kidney was located in my superior right pelvic region and was only 2.5cm in height. Length and width dimensions were normal in both kidneys.

Five years later I had another ultrasound done and my right kidney was located under my right rib cage and was 5cm in height. My left kidney has always been normal and is 5.5cm in height.

For the life of me I can't find out why my kidney changed size (increased) as well as position. I currently have IBS symptoms and was wondering if there could be any connection? Why would my kidney change size?
