Correlation and predictive value of ultrasound twinkling effect of Urolithiasis with chemical composition of calculi
Journal Title: International Journal of Medical Science and Innovative Research (IJMSIR) - Year 2018, Vol 3, Issue 6
Abstract
Background : Although helical CT enjoys the highest sensitivity and specificity levels in detecting Urolithiasis, latest Sonography techniques combined with radiography can be a cost effective method of evaluating renal calculi with equivalent sensitivity and specificity. In evaluating Urolithiasis, if the composition of the stone being studied could be predicted, that knowledge could vastly influence the choice of treatment modality, follow-up schedule and preventive measures against recurrence. .Methodology: This prospective analytical study evaluated Urolithiasis of 30 patients by radiography and sonography to correlate specific findings in the diagnostic methods with the chemical composition of the stones. Result: We were able to evaluate all the Urolithiasis cases by using plain X-ray and ultrasound with a sensitivity and specificity of 100% in the study group. In sonography, we could visualise the ‘Twinkling Artifact’ effect in almost all the patients. On grading the twinkling artifact and comparing our various measurements with the chemical composition of the stones, we detected that the twinkling artifact has a significant correlationship with predominance of COM in the calculi. Conclusion: Sonography and Radiography are reliable diagnostic modalities for evaluation of Urolithiasis and the twinkling artifact effect in sonography can be used to predict the nature and composition of the stone which can assist in choosing further mode of treatment.
