摘      要：Background:Vesicoureteral reflux is the most common urinary congenital anomaly in *** the risk associated with radiation exposure there has been an increasing need for radiation-free method in the diagnosis and follow-up of the vesicoureteral *** aim of our study is to compare conventional urosonography without contrast enhancement and x-ray voiding *** and Methods:Children with recurrent urinary tract infection with suspected vesicoureteral reflux were included to the *** reflux is demonstrated and graded by x-ray voiding *** is used for the evaluation of renal *** sonographic procedure was performed in all *** junction insertion angle was *** diameter and length of the ureterovesical junction were also ***:268 children enrolled to the *** reflux was demonstrated in 62 children by x-ray voiding *** junction insertion angle measurement had a statistically significant relation for right and left vesicoureteral reflux presence(right:r:.646,p:.01 and left:r:.446,p:.01).Diagnosis sensitivity of vesicoureteral reflux with conventional ultrasonography is 95.10%and specificity is 81%(Youden’s index 76.1%)for the cutoff value of the ureterovesical junction insertion angle is 28.6 *** predictive value is 87.2%,negative predictive value is 94.73%and diagnostic accuracy is 86.29%with conventional ***:Measurement of ureterovesical junction insertion angle,length and diameter by conventional urosonography is an easy accessible and cheap technique with high sensitivity and specificity for the diagnosis and followup of the vesicoureteral reflux without exposure to ionizing radiation.
