Imaging assessment of renal injuries in children and adolescents: CT or ultrasound?

Background: Since the introduction of the ALARA ("as low as reasonably achievable") concept, ultrasound (US) has been progressively advocated for paediatric diagnostic imaging. This study aimed to analyse the role and accuracy of US in paediatric renal trauma.

Methods: From 1999 to 2009, the tertiary-care-hospital database was retrospectively evaluated for renal trauma with regards to aetiology, type of injury, diagnostics, management and outcome.

Three-dimensional ultrasonography-based virtual cystoscopy of the pediatric urinary bladder: a preliminary report on feasibility and potential value.

Objective: The purpose of this study was to validate the feasibility and potential of 3-dimensional ultrasonography (3DUS)-based virtual cystoscopy in the pediatric urinary bladder.

Methods: Twenty patients (age range, newborn-14 years) underwent urinary tract ultrasonography and 3DUS of the urinary bladder. From this data set, virtual cystoscopy was reconstructed for visualization of the inner bladder surface.

Subsequent displacement of initially nondisplaced and minimally displaced fractures of the lateral humeral condyle in children.

Background: Although conservative treatment is a well-established method for treating nondisplaced and minimally displaced (< or =2 mm) fractures of the lateral humeral condyle in children, there is still great uncertainty concerning the rate and time course of subsequent displacement. Therefore, the appropriate frequency of radiographic follow-up remains unclear. The aim of the study was to determine the rate of subsequent displacement after conservative treatment of nondisplaced and minimally displaced fractures of the lateral humeral condyle in children.
