ABSTRACT
Objective:To analyze the diagnostic value of colour Doppler ultrasonography and X-ray plain film radiography in upper urinary tract calculi.Methods: 97 cases of upper urinary tract calculi were randomly selected in our hospital between 2012 January and 2013 January, who were examined by colour Doppler ultrasound and X-ray film and then the results were analysed and compared.Results: In the 97 cases with colour Doppler ultrasound, 92 cases were the positive renal calculi, and the effective diagnosis rate was 94.8%. And then in the 97 cases with X-ray film, 67 cases were the positive renal calculi, and the effective diagnosis rate was 69.1%. The positive diagnosis rate in the group with colour Doppler ultrasound was higher than that in the group with X-ray film (x2=16.34,P<0.05). In the 97 cases with colour Doppler ultrasound, 52 cases were the positive ureteral calculi, and the effective diagnosis rate is 53.6%. And then in the 97 cases with X-ray film, 69 cases were the positive ureteral calculi and the effective diagnosis rate was 71.1%. The positive diagnosis rate in X-ray film group was higher than that in the group with colour Doppler ultrasound (x2=10.65, P<0.05).Conclusion: In diagnosis of upper urinary tract calculi, the diagnosis rate of renal calculi is higher by colour Doppler ultrasound and the diagnosis rate of ureteral calculi is higher by X-ray film. Both methods have advantages and disadvantages in inspection, and we should combine them in clinical practice.
ABSTRACT
Objective To assess the effect of arterial embolization in treating hyperthroidism by colour ultrasonography.Methods Forty two cases of hyperthyroidism were treated with thyroid arteries embolization. A few days before and 1, 3, 6 months after embolization, the echograms of thyroids were observed including the volumes of thyroids and the internal diameters of thyroid arteries were measured with colour ultrasonography respectively. The Vs, Vd, Vm, PI, RI were measured with the Doppler and the quantities of blood flow were calculated. The relationships of changes for all these parameters and T 3, T 4 and TSH were analysed. Results Before artery embolization all thyroids were enlarged with diffusely homogenous or heterogenous low echos and nodules in some patients accompanied by widenings of the thyroid arteries and their branches full of blood supply. The volume of thyroids decreased after artery embolization. 1 3 months later the echo of thyroids enhanced and got coarse with decrease of the thyroid vasculature and narrowing of vessel calibers except a few star or spot like blood streams were sometimes seen within the thyroids and no blood flow signals found in some cases. 3 6 months after embolization, the echo of thyroids decreased gradually or unevenly distribnted. All the parameters of blood flow before and after the treatment showed statistically significant differences( P
