Is renal arteriovenous malformation curable?

No: No real treatment unles very symptomatic or riskk oof losing a kidney although the likelyhood of this necessity is small as long as the kidney functions normally. However as you have two kidneys you may not know when and if this kidney faiils without continual followup with your physician and routin urin evaluations.

Yes: Can be embolized usually by an interventional radiologist like myself. Very serious cases the kidney may need to be removed by an urologist.
