Structure and component analysis of uratoma around joint / 局解手术学杂志

ABSTRACT

Objective To analyze the structure and component of gouty tophus around joint, and provide basis to select solvent of gouty tophus and surgical cleaning method.Methods The sample of gouty tophus were obtained from 6 patients in 187 hospital of PLA from January2016 to December 2017, which were rinsed by distilled water, and then dried and accepted other dispose.The sample were analyzed by Fourier Transform Infrared Spectroscopy (FTIR), scanning electron microscope and thermal gravimetric analyzer.Results Sodium urate was the main component of the uratoma, the proportion was 56％;the organic component was about 14％of the uratoma.The microstructure of the uratoma under scanning electron microscope have two forms, the one looks like column crystal and the other like granules head up to lump.Conclusion The main component of the gouty tophus are sodium urate and organic tissues, the possible solvent should react on the both of them.
