A 51-year-old male received ureteroscopic removal of a distal ureteral calculus (ultrasound in A). Fifteen months later, persistent upstream hydronephrosis without evidence of lithiasis at unenhanced MDCT (not shown) led to performing unenhanced magnetic resonance (MR) urography. Pyelographic (B) and axial T2-weighted images showed smooth tapering of the pelvic ureter (arrowheads), without appreciable mural thickening or extrinsic tissue at the coronal T1-weighted image (D), consistent with an iatrogenic stricture
