Two x-rays are seen here. One is a KUB control plain x-ray abdomen and second one is an excretory urography (IVP) taken soon after the control one. Carefully looking an opacity is seen near the upper part of the right sacroiliac joint. The opacity is hard to see because of nearby bony pelvis and sacroiliac joint.The opacity is marked. Excretory urography shows obstruction of contrast material and flow of urine at the site of impacted stone on the right side causing hydroureter and hydronephrosis. Compare right ureter and right kidney with the left one for learning.
