The aim of this study was to determine morphologic and functional benefits of dynamic magnetic rezonans urography (MRU) at pediatric patients with ureteropelvic junction obstruction. Between 2009-2012, sixteen pediatric patients with known ureteropelvic junction obstruction were evaluated by ultrasound and dynamic MRU retrospectively. Eight of them also had diuretic renal scintigraphy. The findings of MRU were then compared with ultrasonography for morphological evaluation, diuretic renal scintigraphy for functional evaluation and against the results of final diagnosis established at surgery. MRU failed in one patient to find obstruction like ultrasound. MRU and ultrasound was successful to evaluate morphology of urınary system all of the other patients. Results were confirmed with surgery. MRU and diuretic renal scintigraphy were similar for functional evaluation. Dynamic MRU is reliable method for morphologic and functional evaliation of pediatric ureteropelvic junction obstruction.
Key words: Ureteropelvic junction obstruction, dynamic magnetic rezonans urography, pediatric patients
