5. Study Description

Brief Summary
The objective of this study is to measure the influence of both short term water restriction and high water intake on total kidney volume, measured by Magnetic Resonance Imaging (MRI) scan in Autosomal Dominant Polycystic Kidney Disease (ADPKD) patients.
Detailed Description
Patients will be randomized to either water restriction for 3 hours or high water intake (20 ml/kg) for 1 hour. Before intervention and after intervention patients will have an MRI scan of the kidneys to measure the total kidney volume (TKV) (differentiated in cortex, medulla and cyst volume). The objective is to identify whether water restriction or high water load will change the TKV. Secondly investigators will analyze different biomarkers (aldosterone, renin, vasopressin/copeptin, urine- and blood-osmolarity) before and after the intervention.
