Screening of parathyroid gland by high frequency ultrasound and the relationship between recurrent urinary calculi and primary hyperparathyroidism.

OBJECTIVE To understand the value of high frequency ultrasound in the clinical screening of parathyroid gland, and to summarize the intrinsic relationship between primary hyperparathyroidism and recurrent urinary calculi. PATIENTS AND METHODS 98 cases of urinary calculi were randomly selected, and the patients were admitted to our hospital from March 2014 to August 2017. A total of 100 healthy subjects were selected as group B in the same period. High frequency color Doppler ultrasonography scan recorded the results. RESULTS Among the subjects in group A, 67 (68.37%) showed parathyroid gland, 14 cases (14.29%) had tumor mass in the parathyroid system, 40 cases more than those in group B (40.00%) and 2 cases (2.00%), (p <0.05). There were 10 cases (10.20%) of primary hyperparathyroidism in group A and no cases of primary hyperparathyroidism in group B (p < 0.05). The occurrence of primary hyperparathyroidism was 26.92% (7/26) in the number of cases, with 3 and more cases of urinary calculi, which was higher than that in the first recurrent cases (3/72), (p<0.005). CONCLUSIONS One of the key causes of recurrent episodes of urinary calculi is primary hyperparathyroidism, which can be applied to high frequency ultrasonography to develop professional screening of parathyroid gland in cases of urinary calculi.
