Renal failure in patients who have performed a pancreas transplantation is a hazard for the outcome for these patients. The beneficial effect of pancreas transplantation for renal function is not clear. It is of major importance to early find patients who develops a decrease in renal function and start treatment early and closely monitor these patients in order to avoid further deteriorating renal function. In order to achieve this, there is a need for a easy, fast and sensitive method to evaluate renal function. In this study the investigators plan to use the non-invasive MR to evaluate changes in renal function.
The purpose of this study is to evaluate the beneficial effect of pancreas transplantation for long term kidney function in patients undergoing single-pancreas transplantation.
