Concordancia de tres pruebas espectroscópicas para el análisis fisicoquímico de cálculos renales

Abstract

This document is based on the research and techniques applied during an internship in the laboratories of the Pontificia Universidad Javeriana. The research project focuses on the characterization of kidney stones obtained from 22 individuals, analyzing their chemical composition and external morphology. Advanced spectroscopic techniques, such as Fourier transform infrared spectroscopy (FTIR), X-ray fluorescence (XRF), and Raman spectroscopy, were used to obtain detailed physicochemical analyses of the samples. Based on the results, kidney stones were classified into three main groups: oxalates, phosphates, and uric acid. In addition, a correlation was established between macroscopic characteristics such as color, texture, and shape of the stones and their chemical composition. The study included samples from Colombian individuals, which is necessary in the national context. The combination of applied spectroscopic techniques offered a robust approach, allowing for a comprehensive characterization that contributes to improving the understanding of kidney stones and strengthening the foundation for prevention and treatment strategies tailored to the Colombian population.
