Does the Hounsfield Unit Value Determined by Computed Tomography Predict the Outcome of Percutaneous Nephrolithotomy?

Abstract

In addition to the size and location of the stones, the HU value determined in the unenhanced CT scan may be one of the parameters affecting PCNL outcomes. PCNL is a more efficient method in stones with higher HU values. Therefore, the HU values may be a useful tool for the selection of the treatment modality in patients with renal stones.
