Abstract
BACKGROUND: Two-dimensional (2DUS) contrast enhanced voiding urosonography has been used in the diagnosis and treatment monitoring of the vesicoureteral reflux in children for over 15 years. The opportunity of performing this examination with the use of three-dimensional static (3DUS) and real-time (4DUS) techniques opens up new diagnostic horizons. OBJECTIVE: To analyze if 3DUS/4DUS bring additional information leading to an increased detection rate or change in the grading of reflux compared to 2DUS and voiding cystouretrography. MATERIAL AND METHODS: We evaluated 69 patients (mean 4.1 years) who underwent 2DUS/3DUS/4DUS contrast enhanced voiding urosonography (ceVUS) and voiding cystourethrography (VCUG) for the diagnosis and grading of vesicoureteral reflux. RESULTS: 2DUS and 3DUS/4DUS urosonography diagnosed 10 more refluxes (7.25%) than cystourethrography and in 3 refluxes (2.17%) detected a higher grade. In 9 refluxes (6.52%) 3DUS/4DUS urosonography and cystourethrography diagnosed a higher grade than 2DUS. There was a statistically significant difference between cystourethrography and 3DUS/4DUS urosonography when the number of detected refluxes and differences in grading were compared. 4DUS enabled a better visualization of reflux than 3DUS. CONCLUSIONS: 3DUS/4DUS techniques bring additional information leading to a change in reflux grading compared to 2DUS and a detect higher number of refluxes compared to cystourethrography.
