X-ray examination revealed a dumbbell-shaped calculus in the right ureter just below the level of the fourth lumbar transverse process (Fig 1). Over the next few days the stone moved downwards to become arrested at the level of the first sacral vertebra. The presence of incipient hydronephrosis on excretory urogram and continued pain prompted cystoscopy, during which a Dormia basket was introduced into the right
