BACKGROUND
Renal osteodystrophy is common in children with chronic renal failure (CRF) and X-ray is an intensive method in the diagnosis of the disease. In this study we compared microfocal radiography with conventional method for the diagnosis of renal osteodystrophy.
METHODS
The X-rays of left wrists of 21 children with CRF and chronic renal insufficiency were taken by conventional and microfocal methods.
RESULTS
Both methods revealed osteopenia in all patients (100%), widening, fraying and cupping of ulnar and radial metaphysis in 10 (47.6%), osteosclerosis in three (14.2%) and pseudofracture in one (4.7%) patient. Microfocal radiography demonstrated osteosclerosis in one patient, pseudofracture in four and subperiosteal resorption in five patients that were not detected by conventional method.
CONCLUSION
Two methods were found to be significantly different in demonstrating the changes due to rickets and hyperparathyroidism and it is concluded that microfocal radiography may be preferred in the diagnosis of childhood renal osteodystrophy.
背景
肾性骨营养不良在慢性肾衰竭（CRF）患儿中很常见，X线是诊断该病的常用方法。在本研究中，我们比较了微焦点X线摄影与传统方法在诊断肾性骨营养不良中的应用。
方法
对21例CRF和慢性肾功能不全患儿的左手腕进行传统和微焦点X线摄影。
结果
两种方法均显示所有患者（100%）有骨质减少，10例（47.6%）患者尺桡骨干骺端增宽、毛糙和杯口状改变，3例（14.2%）有骨质硬化，1例（4.7%）有假骨折。微焦点X线摄影显示1例患者有骨质硬化，4例有假骨折，5例有骨膜下吸收，而传统方法未检测到这些情况。
结论
发现两种方法在显示佝偻病和甲状旁腺功能亢进引起的变化方面有显著差异，得出结论：在儿童肾性骨营养不良的诊断中，微焦点X线摄影可能更具优势。
