甲状旁腺超声检测对尿毒症继发甲状旁腺功能亢进的诊治意义

目的:探讨高分辨率超声对尿毒症继发性甲状旁腺功能亢进(甲旁亢)的诊断价值及与血清甲状旁腺素(PTH)间的相关性.方法:对55例尿毒症患者进行甲状旁腺的超声检查,并测定血清PTH、钙、磷水平.结果:55例中52例患者(94％)测到增大的甲状旁腺64枚,其中测及2枚以上者11例(20％).多枚甲状旁腺患者,甲状旁腺体积、血清PTH及磷水平均较单枚患者明显增加(P<0.01),上述指标随病程的延长变化更加明显;但血清钙水平并无明显变化.结论:尿毒症甲状旁腺的大小与血清PTH及磷水平存在一定关系.超声对尿毒症继发性甲旁亢患者的甲状旁腺肿大有诊断价值.

Ultrasonographic diagnosis of parathyroid gland in secondary hyperparathyroism of uremic patients

Objective: To evaluate the value of high resolution ultrasonography for diagnosis of secondary hyperparathyroism(HPT) in uremia and its relationship with serum parathyroid hormone(PTH). Methods: Ultrasonography was used to examine parathyroid gland and serum PTH, calcium,phosphorus in 55 cases of uremic patients. Results: Totally 64 parathyroid glands in 52 patients(94%) and over 2 glands in 11 cases(20%) were found. The volumes of parathyroid gland was larger and the value of PTH was abviously increased in over 2 glands than in single gland( P <0.01), the above indexes increased obviously with the development of the disease,but the serum calcium remained unchanged. Conclusion: The size of parathyroid glands and serum PTH, calcium and phosphorus is related to certain extent.Ultrasonography is a useful tool for the detection of enlarged parathyroid glands in patients with secondary HPT.
