Vesicoureteral reflux (VUR) is a condition characterized by the retrograde flow of urine from the bladder to the upper urinary tract. It is one of the most common urological morbidities in the pediatric population. VUR is usually diagnosed during UTI workup, hydronephrosis workup, or screening a sibling of a child with VUR. The gold standard imaging to diagnosis VUR is a voiding cystourethrogram. Patients with VUR are treated with the aim of preventing recurrent febrile urinary tract infections, preventing renal damage, and minimizing/preventing the adverse effects of treatment. Among surgical options, open vesicoureteral reimplantation is the traditional technique, but with the introduction of laparoscopic and robotic surgery, minimally invasive options have emerged, such as robotic extravesical vesicoureteral reimplantation (REVUR). The topic of this chapter is the LUAA technique named after the steps to create an ideal detrusor tunnel and detrusorrhaphy. The technique stands out for its precision and improved anastomosis, thanks to the robotic system. Although open reimplantation remains the standard, REVUR offers advantages in precision and minimally invasive dissection.
