Predicting posterior urethral obstruction in boys with lower urinary tract symptoms using deep artificial neural network.

Purpose: To assess the prediction model for late-presenting posterior urethral valve (PUV) in boys with lower urinary tract symptoms (LUTS) using artificial neural network (ANN).

Materials And Methods: 408 boys aged 3-17 years (median 7.2 years) with LUTS were examined and had bladder diary, ultrasound, uroflowmetry, urine, and urine culture.

Correction to: Melatonin as an alternative sedation method during magnetic resonance imaging in preschool children with musculoskeletal problems.

AbstractMagnetic resonance imaging (MRI) in preschool children is often challenging due to excessive motion artifacts. Sedation or general anesthesia (GA) are commonly used to prevent children from moving in the MRI scanner, with increased risk for cardiopulmonary complications and requirement for skilled personnel. Herein we investigated whether oral melatonin, a natural hormone implicated in circadian rhythm regulation, could be used as an alternative sedation method prior to the MRI in preschool children with musculoskeletal problems.
