摘要: Abstract Objective We aimed to search if the renal parenchymal attenuation measurements on unenhanced CT scans could be useful in differentiating acutely obstructed kidneys from chronic cases or unobstructed kidneys. Material and methods Unenhanced of 101 patients were retrospectively reviewed. Thirty-two with unilateral acute obstruction, 34 obstruction due various reasons 35 control subjects included study. The densities both measured, upper poles, middle portions, lower poles each kidney. mean calculated all three groups subjects. Secondary signs such as perinephric stranding, size ureteral stone, degree hydronephrosis also noted for Results value side was than side, 24.21±3.68 30.68±4.75 respectively ( p Conclusion Renal differences kidney same patient cases.
