This video of bilateral ureteroscopy in a 16-year-old male with cystinuria highlights several pragmatic strategies for efficient ureteroscopy while minimizing ionizing radiation.

Considerations for treatment strategies, use of safety wires, and follow-up imaging are also discussed.

Dr. Ellison provides an excellent video demonstrating the considerations for retrograde intrarenal surgery in pediatric patients, drawing particular attention to the importance of minimizing radiation and anesthetics. These include optimizing fluoroscopy settings, using ultrasound as the preferred diagnostic imaging modality, and performing a bilateral ureteroscopy with judicious use of ureteral stents on a string. These practices are even more important for children with cystinuria who are almost certain to have many operations and countless imaging studies over their lifetime, as suggested by the multifocal subendothelial crystallization in each kidney.

Dr. Ellison demonstrates how many of the techniques originally developed for adults can be employed by skilled pediatric endourologists. His deliberate choice to limit radiation, employ ultrasound where possible, and complete a bilateral procedure with one anesthetic are relevant to both adult and pediatric endourologists looking to optimize outcomes.
