Influencing factors of early hypocalcemia after microwave ablation for treating secondary hyperparathyroidism
Objective To observe the influencing factors of early hypocalcemia after microwave ablation(MWA)for treating secondary hyperparathyroidism(SHPT).Methods Data of 82 SHPT patients who underwent MWA were retrospectively analyzed.The patients were divided into hypocalcemia group(n=36)and non-hypocalcemia group(n=46)based on presence of early hypocalcemia after MWA or not.Patients'age,gender,body mass index(BMI),dialysis method,dialysis time and number of lesions were compared between groups,so were baseline blood calcium,blood phosphorus,intact parathyroid hormone(iPTH),alkaline phosphatase(ALP),hemoglobin,albumin,creatinine,uric acid and 2 5-hydroxy vitamin D3.Logistic analysis was performed to screen the influencing factors of early hypocalcemia after MWA.Results Significant differences of dialysis methods,number of lesions,blood calcium,iPTH and ALP were found between groups(all P<0.05).Univariate and multivariate logistic regression analysis showed that the number of lesions,iPTH and ALP were all independent influencing factors of early hypocalcemia after MWA for treating SHPT(all P<0.05).Conclusion The number of lesions,iPTH and ALP were influencing factors of early hypocalcemia after MWA for treating SHPT.
