With the rapid development of science and technology, surgery has entered the minimally invasive era. But in the field of child urinary surgery, some more complex laparoscopic surgical reconstruction (such as ureter replantation) to support with high technical requirements, long learning curve, many doctors couldn't successfully through the learning curve and give up, which make laparoscopic cannot serve patients universally. Even after the learning curve, surgeons are often in an awkward position during these complicated operations. Many surgeons have been suffering from chronic repetitive strain injuries to bones and muscles. A surgeon who spent years mastering laparoscopy soon had to scale back or even abandon it because of bone and muscle strain . Since robot-assisted laparoscopic surgery was proposed in the late 1990s, it has overcome the technical defects of traditional laparoscopic surgery due to its advantages such as 3D surgical field, 15 times magnification effect, 7 degrees of mobility, and tremor filtering, and has been rapidly developed and applied in the surgical field. This chapter focuses on the application of robot-assisted ureterovesical replantation, mainly diseases including vesicoureteral reflux, ureterovesical junction obstruction, ectopic ureteral opening, bladder diverticulum, etc., and vesicoureteral reflux is the most common in children.
