What instances will you start outpatient steroids in patients with nephrotic syndrome of unknown etiology prior to obtaining a kidney biopsy?  

It is Friday, your patient presents with classic acute nephrotic syndrome, your biopsy Friday won't have results (if not longer if you need EMs which you need for MCD) until Tuesday. I never think a few days of steroids is a big deal, so I can see doing it.

I don't remember ever doing that. Steroids have a long list of side effects. I try to minimize using them as much as possible.
