Abstract

Cilj ovog rada bio je opisati organske minerale koji se javljaju u bubrežnim kamencima. Najvedi postotak bubrežnih kamenaca čine kamenci građeni od kalcijskih oksalata, weddellita i whewellita. Urični kamenci se javljaju u obliku uricita i dihidrata. Bubrežni kamenci jedna su od najčešćih bolesti mokračnog sustava, te nam je znanje o njihovom kemijskom sastavu i morfologiji važno za razumijevanje načina njihovog nastanka i kasnijeg liječenja. Za analizu kemijskog sastava i morfologije korištene su infracrvena spektroskopija (FT-IR), renTgenska difrakcija na prahu (XRD) i pretražujudi elektronski mikroskop (SEM). Rezultati su pokazali da se većini uzoraka sastoji se od whewellita i hidroksiapatita. U malim postocima zastupljeni su weddellit, uricit i dihidrat mokradne kiseline.

Abstract (english)

The purpose of this study was to identify organic minerals in urinary calculi. Calcium oxalates, whewellite and weddellite, are the most common organic minerals in calculi. Uric acid calculi crystallizes in anhidrous (uricite) and dihydrous form. Kidney stone disease is increasingly common. The identification of the chemical composition and morphology is important for understanding their etiology and proper management. Calculi were subjected to infrared spectroscopy (FT-IR), X-ray powder diffraction (XRD) and scanning electron microscopy (SEM). The results show that the whewellite and hydoxyapatite are most common compound. Other minerals such as weddellite, uricite and uric acid dihydrate are found.
