Ultrasonography and correlative factor of secondary hyperparathyroidism in maintenance hemodialysis patients
Objective To realize ultrasonography and correlative factor of secondary hyperparathyroidism in maintenance hemodialysis patients.Methods 73maintenance hemodialysis patients with secondary hyperparathyroidism were divided into imaging group and no imaging group.The patients were underwent ultrasonic,PTH,ALP,Ca,P testing and recorded age,sex,duration of dialysis.The location,number,size,echo and blood flow in imaging group were recorded.Imaging group was divided into rich blood flow group and no rich blood flow group according to blood flow and divided into calcification group and no calcification group according to level of serum calcium.Results 57patients had parathyroid gland image in 73patients with SHPT(78.1%).The ultrasound findings had 1to 4low level echo nodes around the thyroid lobe dorsal.Serum value of PTH,ALP,Ca and duration of dialysis in imaging group were higher than that in no imaging group.Number and size of parathyroid gland were positive correlation to serum value of PTH and ALP.Value of PTH,ALP,P and Ca×P in rich blood flow group was higher than that in no rich blood flow group.Value of ALP,Ca and duration of dialysis in calcification group were higher than that in no calcification group.Conclusion Ultrasound image of parathyroid gland is high,representative in SHPT patients.Ultrasound testing could provide the secundum for clinical diagnosis and treatment.
