Kidney or renal biopsy is the excision of a tissue sample from the kidney for microscopic analysis to determine cell morphology and the presence of tissue abnormalities. This test assists in confirming a diagnosis of cancer found on x-ray or ultrasound or to diagnose certain inflammatory or immunological conditions.
The Three Sisters are a subgroup of the Cascade volcanoes west of Bend in central Oregon, consisting officially of North, Middle, and South Sisters (all approximately 10,000 ft high), though Mt. Bachelor (aka Bachelor Butte) & Broken Top are also in the immediate vicinity.
Suggestions for New Visitors. Three Sisters is essentially broken into two areas which are the East Section and the West Section. It may appear on a map that these areas are spread-out, however everything is much closer to each other then you realize. The East section you would park in the first small lot.
