Analysis of the Predictive Capacity of the Clinical Variables That Indicate the Performance of Voiding Urosonography in the Study of Vesicoureteral Reflux in Children.

Introduction: Voiding urosonography (VUS) is a dynamic imaging technique which evaluates the lower urinary tract by introducing sonographic contrast into the bladder, preferably used in the diagnosis of vesicoureteral reflux (VUR). Our goals were to describe the clinical indications for performing a VUS for VUR's diagnosis and analyse its diagnostic reliability.

Material And Methods: Cross-sectional study carried on patients under 15 years old with a VUS taken between November 2013-2020.

Eighteen years of experience with pediatric nutcracker syndrome: the importance of the conservative approach.

Introduction: Nutcracker syndrome (NS) defines an entity generated by the compression of the left renal vein resulting in venous hypertension, which transmitted in a retrograde direction may cause hematuria, proteinuria, and varicocele. The literature concerning exclusively pediatric patients is very rare.

Objective: To report the authors' experience with pediatric NS in the last 18 years.
