3 doctors agree

In brief: Maybe

Gadolinium the contrast agent used for MRI is not be used if the kidney function is low ie GFR less than 30.
Otherwise it is probably ok.

In brief: MRI contrast

The contrast used for MRI is gadolinium. It is not toxic to kidneys.
CT contrast is toxic to kidneys. IVP contrast is toxic to kidneys.

In brief: Wrong study

Nephrologist likely knew what s/he is doing.
A mag3 nuclear renal scan would be the correct test to evaluate comparative function between left ; right ; degree of obstruction present. Not mri. Ordering dr. Either does not know what s/he is doing or worse has a financial stake in the mri. Would be worth reporting to state medical board of registration if the latter.
