Comparison of the effects of colour Doppler ultrasonography and X-ray plain film radiography in diagnosis of upper urinary tract calculi / 中国医学装备

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.
