The bone mineral density of patients undergoing peritoneal dialysis (PD) is low compared to a healthy population. No studies have been conducted to investigate whether the presence of peritoneal dialysate affects dual-energy X-ray absorptiometry (DXA) results. We hypothesized that the presence of peritoneal dialysate would not affect the measurement of bone mineral density (BMD) or bone mineral content (BMC) in the spine. Thirty patients on PD had DXA scans of the lumbar spine and hip completed before and after the drainage of peritoneal dialysate. A paired t-test was used to compare the difference in area, BMC, and BMD before and after drainage of dialysate. A significant difference was found in the BMC of the spine before and after the drainage of dialyzate. We recommend that peritoneal dialyzate be removed prior to scanning patients on PD and that densitometry technologists should be observant about the presence of peritoneal dialysate.
与健康人群相比，接受腹膜透析（PD）的患者骨密度较低。尚未开展研究来调查腹膜透析液的存在是否会影响双能X线吸收测定法（DXA）的结果。我们假设腹膜透析液的存在不会影响脊柱骨密度（BMD）或骨矿物质含量（BMC）的测量。30例接受腹膜透析的患者在排出腹膜透析液前后完成了腰椎和髋部的DXA扫描。采用配对t检验比较透析液排出前后面积、BMC和BMD的差异。发现透析液排出前后脊柱的BMC存在显著差异。我们建议在对接受腹膜透析的患者进行扫描前清除腹膜透析液，并且密度测定技术人员应留意腹膜透析液的存在。
