meaning of Ureter Dilatation during ultrasonography in infants for evaluating vesicoUreteral reflux
European Journal of Radiology, 2015Co-Authors: Yae Won Park, Myung Joon Kim, Sang Won Han, Dong Wook Kim, Mi Jung LeeAbstract:Abstract Purpose To investigate the meaning of Ureter Dilatation during ultrasonography (US) in infants for evaluating vesicoUreteral reflux (VUR). Materials and methods We retrospectively reviewed abdominal US images of infants who were diagnosed with urinary tract infection (UTI group) or only hydronephrosis without UTI (control group). Hydronephrosis (graded 0–4) and Ureter Dilatation (present or absent) were evaluated on each side with US. Voiding cystourethrography (VCUG) within 3 months time interval with US was also reviewed and VUR was graded (0–5) on each side. Hydronephrosis, Ureter Dilatation, and VUR were then compared between the two groups. Results Four hundred and three infants (142 in the UTI group and 261 in the control group) were included and VCUG was performed in 129 infants (68 in UTI and 61 in control groups). VUR grades were not different between the two groups ( p = 0.252). Hydronephrosis grade was not related to VUR in either group ( p > 0.05). However, Ureter Dilatation had a significant relationship with VUR in the UTI group ( p = 0.015), even among patients with a high-grade VUR ( p = 0.005). Whereas, Ureter Dilatation was not associated with VUR in the control group ( p = 0.744). The relationship between Ureter Dilatation and VUR was different between the two groups for both all grades ( p = 0.014) and high-grade ( p = 0.004) VUR. Ureter Dilatation had 66.7% sensitivity, 80.3% specificity, and 79.4% accuracy for evaluating high-grade VUR in the UTI group. Conclusion Ureter Dilatation on US can be a helpful finding for detecting VUR in infants with UTI, but not infants without UTI.

does retrovesical Ureter Dilatation predict vesicoUreteral reflux in infant less than age one
Journal of Pediatric Urology, 2010Co-Authors: Chang Hee Hong, Won Sik Jang, Sang Won HanAbstract:Purpose Some have reported that because there is physiologic Ureter Dilatation in infant less than age 1, retrovesical Ureter Dilatation (RUD) in ultrasonogram (US) has not clinical implication. Therefore, we investigated the correlation between retrovesical Ureter Dilatation and VUR in infant less than age 1. Material and Methods Between January 2006 and December 2008, 286 patient who underwent VCUG and US were included in this study. The patients with neurogenic bladder, megaUreter and duplicating system were excluded. Mean age was 6.1 (0.7∼12.0) months, 235 patients were boys. Results Out of 572 Ureters of 286 patients, 104 (18.2%) showed RUD on US, and 39 (37.5%) of 104 Ureters showed VUR. But, 123 (26.3%) Ureter of 468 without RUD showed VUR, and then there was significant difference between two groups (p=0.023). Meanwhile the specificity to predict VUR by RUD was 84.1%. We analyzed that the grade distribution of hydronephrosis and VUR according to existence of RUD. As a result, the grade of hydronephrosis and VUR was significantly high in case of existence of RUD (p Conclusions There was also significant correlation between RUD and VUR in infant less than age one. Moreover, RUD was associated with high grade VUR and hydronephrosis. Therefore, RUD is useful factor to predict VUR, especially with PUD.
