Abstract：Objective To assess the predictive value of the bladder deformation index(BDI)in determining upper urinary tract(UUT)damage among patients with neurogenic bladder(NB).
Methods Clinical data of 132 NB patients admitted to Beijing Bo'ai Hospital from January,2015 to December,2018 were retrospectively analyzed.Patients were divided into UUT damage group and normal UUT group according to the presence or absence of hydronephrosis.The demographics,biochemical parameters and video-urodynam-ics(VUDS)findings were collected,and BDI was calculated.Receiver operating characteristic(ROC)curves were utilized to evaluate the predictive capability.
Results There were 54 patients in UUT damage group and 33 in normal UUT group.The course of disease,creatinine level and BDI were siginificantly different between two groups(P<0.05),while the area under the curve were 0.686,0.836 and 0.928,respectively.
Conclusion Course of disease,creatinine level and BDI are associated with UUT damage in NB patients,and BDI dem-onstrates the highest sensitivity and specificity,which may play a role in diagnosis of UUT damage.
