Recently, there is growing awareness and concerns about the overuse of CT in evaluation of patient with ureteric colic, particularly the radiation exposure, overuse and costs. Instead of the recent advancement in Ultrasound technology, most of the radiologists have difficulty in localizing the ureteric stones. Many recent studies have reported and encouraged the use of twinkling sign to improve the accuracy of ultrasound to detect ureteral stones. In this retrospective study, we evaluated the accuracy of Ultrasound (gray-scale and Color Doppler), in diagnosis of ureteral calculi. METHODS We conducted this retrospective study by reviewing the medical records of patients diagnosed with acute ureteric colic in the emergency room and in the urology outpatient from January 2009 to December 2013.900pt were diagnosed with ureteric stone and all of them underwent ultrasound as the primary imaging modality. Sensitivity, specificity, positive and negative predictive value in determining the size, position of the stone in the ureter by Ultrasound has been documented. RESULTS Out of 900 patients, there were 800 males (90 %) and 100 females (10%). Age range was 13–65 years. Our study found that color Doppler ultrasound with twinkling sign, diagnosis was made with confidence in 835 cases (92.7%). 65patients whom failed the ultrasound, the stones were confirmed by helical CT, failure to detect the stone was mainly due to poor visualization (due to bowel gases and obesity) and smaller size of stone. Right side stones were seen in 338 (37.6%) patients while left side stones were seen in 562 (62.4%). Stones were detected bilaterally in 4 cases (0.4%). The range of stones size was 3–1.5mm There were 190 (21.1%), 77 (8.5%) and 633 (70.5%) upper, middle and lower ureteral stones. CONCLUSIONS There is no doubt that Spiral CT is superior in the demonstrating of ureteral calculi. The present study emphasized that utilization of color Doppler ultrasound with twinkling in trained hands can provide an excellent alternative modality with high sensitivity and specificity in diagnosis of acute ureteric colic and with confidence can be used as first imaging modality, hence we could avoid high cost, higher radiation dose and high workload. © 2015 by American Urological Association Education and Research, Inc.FiguresReferencesRelatedDetails Volume 193Issue 4SApril 2015Page: e118-e119 Advertisement Copyright & Permissions© 2015 by American Urological Association Education and Research, Inc.MetricsAuthor Information Arun Panackal More articles by this author Santhosh Kumar More articles by this author Expand All Advertisement Advertisement PDF downloadLoading ...
