Abstract:
[Objective]To study the relationship between bridging septa thickening in the perinephric space and split renal function in acute unilateral upper urinary tract obstruction.[Methods]50 patients with acute unilateral upper urinary tract obstruction by calculus were analyzed retrospectively. According to the images of multi-slice spiral CT (MSCT)scanning,all cases were divided into thickened bridging septa group(n=25)and normal bridging septa group (n=25),The CT values of renal cortical in the plain(CTp)and renal cortical enhancing(CTe)phase were measured, the difference of increasement value(CTe-CTp)and the CT value ratio of the ipsilateral and opposite in renal cortical phase was analyzed by independent sample T test.[Results]The CT increasement value of bridging septa thickening and normal group were(103±30)HU and(128±24)HU respectively,the difference between the two groups was statistically significant(P<0.01);and CTac/CTuc were 0.81±0.13 and 0.96±0.06 respectively(P<0.01).[Conclusion]Thickening of bridging septa in the perinephric space with acute unilateral upper urinary tract obstruction will weaken the enhancement of renal cortical,and increased the likelihood of split renal function impairing.
