Noninvasive: Advantage: noninvasive disadvantage: it can take several months for it to work, several sessions, risk of causing a cancer, etc. Depending on the size, location, symptoms, etc. Embolization, surgery, stereotactic radiosurgery are some of the ways to treat avm. A consultation with neurosurgeon, neuroradiologist, radiation oncologist can determine, what is the best way to treat your condition.

AVM : I'm not an expert in treating these disorders, but gamma knife can be an option for avms under a certain size with specific characteristics in eloquent areas of the brain where surgical treatment is not an option. One can also make the argument for small surgical lesions in non eloquent areas but gamma knife treatment window is longer 2 years sometimes and you go with 2 years of rupture risk.
Dr. Joshua Garren

...: Advantages: no risk of surgery. Less damage to surrounding brain. Less damage to brain traversed to get to the avm during surgery. Less pain. Disadvantages: takes time for the risk of bleeding to drop. Avm may not be obliterated. It may require a second radiosurgery, later on.

Often none: Unless it leaks, there would be no symptoms in most cases. Leaking can cause intense headache or stroke-like symptoms such as focal weakness, loss of speech or vision. Avm discovered after a minor stroke can be corrected before a major stroke. Family history of avm may prompt investigation in someone with no symptoms.

In clinical studies, which usually include patients undergoing evaluation with urologic or vascular imaging techniques, the incidence ranges from 1 case per 1000-2500 patients.

Renal AVM: Renal arteriovenous malformations (avms) and fistulas include various abnormal connections between the intrarenal arterial and venous systems. They cause hematuria (blood in the urine, which may not be visible to the naked eye) and are associated with hypertension. Gross (visible) hematuria is the initial symptom in about 75% of patients. Also can get kidney pain due to blood clots.
