将20例经手术取出的肾盂鹿角形结石或多发性结石在严格的无菌操作下锯开,刮取其表层、中层与核心层的碎屑浸液作细菌培养。结果各层可堵养出细菌者6例,其中以大肠杆菌为主.将结石同时作化学定性和红外光谱分析,大多数(90%)为碳酸磷灰石,与一般文献报道以磷酸镁铵为主略有不同。因而可认为由于感染源、饮食习惯和环境的不同,各地区“感染石”的成份可能有差异。
20 cases of surgically removed renal pelvis antragmites or multiple stones were sawed under strict aseptic operation, scrape the surface layer, the middle layer and the core layer of debris immersion for bacterial culture. Results Six cases of bacteria were blocked in each layer, of which Escherichia coli was the mainstay.At the same time, the stones were analyzed by chemical qualitative and infrared spectroscopy, the majority of which (90%) were carbonated apatite.And generally reported in the literature as ammonium magnesium phosphate The main slightly different. Therefore, it may be considered that due to the different sources of infection, eating habits and the environment, the ingredients of “infected stone” in different regions may differ.
