Research from University of Health Sciences Provides New Study Findings on Urology (Effect of the Hounsfield Unit Calculated on the Non-contrast Computed Tomography of Kidney and Ureteral Stones on the Success of Fragmentation with a Holmium:...).

A recent study conducted by the University of Health Sciences investigated the impact of stone density on the success of ureterorenoscopy (URS) and retrograde intrarenal surgery (RIRS) for kidney and ureteral stones. The study included 566 patients who underwent URS or RIRS, and various factors such as stone density, size, volume, and operative time were recorded. The results showed that stone density, size, and volume were positively correlated with residual stone size and operative time. Additionally, high stone density was found to negatively affect the success of treatment, even in cases with small stone size and volume. [Extracted from the article]
