Background: Surgical coaching has been proposed as a mechanism to fill gaps in proficiency and encourage continued growth following formal surgical training. Coaching benefits have been demonstrated in other surgical fields; however, have not been evaluated within pediatric urology. The aims of this study were to survey members of The Societies for Pediatric Urology (SPU) to assess the current understanding and utilization of surgical coaching while gauging interest, potential barriers and personal goals for participation in a coaching program.

To bridge gaps in proficiency and encourage life-long learning following training, coaching models have been utilized in multiple surgical fields; however, not within pediatric urology. In this review of our methodology, we describe the development of a coaching model at a single institution. In our initial experience, the perceived most beneficial aspect of the program was the goal setting process with logistics around debriefs being the most challenging.

Background: Although voiding cystourethrogram (VCUG) is currently the gold standard in VUR evaluation, there is ionizing radiation exposure. Contrast-enhanced voiding urosonography (CEVUS) uses ultrasound contrast agents to visualize the urinary tract and has been reported to be safe and effective in VUR evaluation in children. CEVUS application has yet to be specifically described in VUR evaluation in the pediatric kidney transplant population.
