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.
Unfortunately, during the war, the elder was killed and was unable to reverse the spell on the three sisters. As a result they were trapped in their rock forms in the Blue Mountains. A more scientific explanation of the formation of the Three Sisters is the theory of erosion. Due to the Blue Mountains being made predominantly of sandstone, the rocks quickly wear away under the impact of the sun, the wind and the rain.
