Objective: To investigate the diagnostic value of color Doppler ultrasonography in detecting calcifications in thyroid nodules for benign and malignant thyroid nodules. Methods: This study selects 108 patients with thyroid nodules who underwent color Doppler ultrasonography at designated hospitals from June 2013 to June 2018 as study subjects, retrospectively analyzes their general patient data, preoperative color Doppler ultrasound data and postoperative pathological diagnosis results, and discusses the diagnostic value of calcification rate, calcification type and calcification characteristics for benign and malignant thyroid nodules. Results: The results show that preoperative color Doppler ultrasonography found 112 thyroid nodules in 108 patients, including 72 benign nodules and 40 malignant nodules; pathological analysis confirmed 124 thyroid nodules, including 78 benign nodules and 46 malignant nodules; the diagnostic coincidence rate of color Doppler ultrasound is 90.32% (112/124), the misdiagnosis rate is 9.68% (12/124), the specificity is 86.94%, and the sensitivity is 81.27%; in these 112 thyroid nodules, 89 nodules were calcified accounting for 79.46%; in 72 benign nodules, 13 nodules were calcified accounting for 18.06%; in 40 malignant nodules, 17 were calcified accounting for 42.50%; the calcification of malignant nodules was significantly higher than that of benign nodules; in 72 benign nodules, 6 cases is coarse calcification accounting for 8.33%, 3 cases is cyclic calcification accounting for 4.16%, and cyclic and coarse calcification are only 23.46% sensitive to thyroid cancer; in 40 malignant nodules, 3 cases is coarse calcification accounting for 7.5%, and 2 cases is cyclic calcification accounting for 5.00%. Conclusions: According to the analysis, the calcification in thyroid nodules has relatively high sensitivity and specificity for the diagnosis of benign and malignant nodules and it can be used as a specific index for screening thyroid cancer.

AbstractObjective:  To prove that ureteric jet examination using Color Doppler Ultrasonography (CDU) can be used as a diagnostic tool to predict success of retrograde Double J Stent insertion in uterine cervicis carcinoma patients with hydronephrosis.Materials and Methods: This observational analytic study took 32 samples since May until October 2013. Before, the ureteric jet were counted for 5 minutes using CDU, then continued on the same day with cystoscopy and retrograde DJ Stent insertion. The analysis was using Chi-Square and also Coefficient Contingency test.Results: In both Chi-Square and Coefficient Contingency test, it is proven a significant correlation between success of retrograde DJ Stent insertion and Blood Urea Nitrogen (BUN), creatinine value, grade of hydronephrosis and also ureteric jet examination using CDU, with probability value (p < 0,005). The normal of BUN, creatinine level and the lower grading of hydronephrosis, the more likely successful DJ Stent insertion. Successfulness of DJ Stent insertion is also greater in a positive ureteric jet samples on examination using CDU, with sensitivity value 90,9% and specificity 89,5%, positive predictor value 83,3%, negative predictor value 95% and accuracy value 0,9.Conclusion: Ureteric jet frequency examination using CDU can be used as a success predictor of retrograde DJ Stent insertion in hydronephrosis uterine cervicis carcinoma patients with sensitivity value 90,9% and specificity 89,5%.Keywords: Ureteric jet, Color Doppler Ultrasonography, Double J Stent, Uterine Cervicis Carcinoma
