One day after PCNL treatment of right-sided urolithiasis, unenhanced (A) and contrast-enhanced (B) MDCT obtained in a 75-year-old female revealed mild uniform thickening of the pelvis (thin arrows) consistent with suburothelial haemorrhage and/or inflammation, plus minimal posterior perirenal blood (arrowheads), which did not require therapy. Two years later, a coronal MIP reformatted image from MDCT urography (C), requested because of worsening renal function, showed persistent dilatation of the renal pelvis due to iatrogenic stricture of the ureteropelvic junction, with preserved parenchymal function and collecting system opacification, which was treated with long-term nephrostomy
