Hello and welcome to HCM,

The MRI report suggests that you are suffering from reflux nephropathy causing chroniv pyelonephritis.
Reflux nephropathy is caused when urine moves back from the urinary bladder to the kidneys. There are many reasons for the reflux. An obstruction at any level can cause reflux.
The back flow of the urine causes dilatation of the pelvi-calyceal system and thus destruction of the kidney normal parenchyma.
This is visible on the surface as cortical scarring.
However, the dilatation is limited only to the pelvis and not the entire kidney.
Due to the dilatation of the renal pelvis, a part of the pelvis has become extra renal or outside the confines of the kidney.

You need to consult a nephrologist.
Further management will depend on the functional capacity of the kidney.
If it is compromisec below a certain level, it may have to be removed surgicall.
However, a person can survive well with one kidney also as the remaining kidney takes over the function of the remaining kidney.

Thanks and take care
