Coronal maximum intensity projection (MIP) from CECT urogram (a) of a 68-year-old man with diffuse metastatic prostate carcinoma (note sclerotic metastases in spine) treated with external beam RT for pelvic disease remotely. Moderate hydroureteronephrosis is present in the right collecting system with a smooth tapered long segment narrowing of the mid right ureter (white arrow) in keeping with a radiation induced ureteric stricture. Overhead AP radiographs from antegrade urogram (b) through indwelling nephrostomy tube (not shown) in a different 65-year-old man with previous history of colonic carcinoma treated with low anterior resection and pelvic RT depict a classic radiation induced stricture (black arrows) with smooth, tapered margins and long segment involvement just above the uretero-vesicle junction
