The above ultrasound images show multiple, small calculi (3 to 4 mm. in size) in both ureters. Color doppler imaging shows twinkling artefacts posterior to the calculi. There is mild dilation of the right ureter. Ultrasound images taken with an ATL ultrasound machine, courtesy of Mr. Shlomo Gobi, Israel.

This 3 D ultrasound image shows a calculus lodged at the distal end of the right ureter at the vesico-ureteric junction (arrowheads). 3-D imaging leaves little to the imagination in such cases. Ultrasound image taken using a Philips IU-22 ultrasound system, by Dr. Ravi Kadasne, UAE.
