摘要

本病例报告描述了一名41岁女性,无明显病史,体重指数(BMI)正常,因输尿管膀胱连接处主要由方解石(CaCO3)组成的5.5mm x 9mm结石而出现输尿管肾积水。与膀胱炎和肾周脂肪浸润相关的肾结石被自发排出并随后进行分析。光学显微镜检查显示,这是一颗灰色均匀的石头,表面粗糙,有白色晶体。傅里叶变换红外光谱(FTIR-ATR)证实了石头的成分是纯方解石,显示出表明其晶体结构的特征吸收带。患者报告长期使用多种维生素和植物性补充剂,可能导致结石形成。讨论包括方解石尿石症的见解,强调了影响结石形成的碱性尿液pH值和钙代谢等因素,强调了补充剂使用者管理肾结石风险的复杂性。

A Rare Pure Calcite Urolithiasis Confirmed by Infrared Spectroscopy.

This case report describes a 41-year-old woman with no significant medical history and a normal body mass index (BMI), who presented with ureterohydronephrosis due to a 5.5mm x 9mm calculus composed primarily of calcite (CaCO3) at the ureterovesical junction. The kidney stone, associated with cystitis and perirenal fat infiltration, was spontaneously expelled and subsequently analyzed. Optical microscopy revealed a grey homogeneous stone with a rough surface and white crystals upon examination. Fourier-transform infrared spectroscopy (FTIR-ATR) confirmed the stone's composition as pure calcite, displaying characteristic absorption bands indicative of its crystalline structure. The patient reported long-term use of multiple vitamins and plant-based supplements, possibly contributing to stone formation. The discussion includes insights on calcite urolithiasis, highlighting factors such as alkaline urine pH and calcium metabolism that can influence stone formation, underscoring the complexity of managing kidney stone risk in supplement users.
