Abstract

Open dismembered pyeloplasty is the most commonly used procedure to treat ureteropelvic junction obstruction (UPJO) in children. Due to the developments in the minimally invasive technology, endoscopic treatment, laparoscopic and robotic pyeloplasty are becoming more popular every day, and being successfully used in the management of UPJO in children as is the case in adults. Endoscopic endopyelotomy should be preferred in selected cases such as children with reccurrent UPJO or those without crossing vessels. Laparoscopic and robotic techniques are comparable after placement of trocars, and robotic arms. It can be used via transperitoneal or retroperitoneoscopical routes. Minimally invasive techniques are advantageous with shorter hospitalization period and lower postoperative analgesic requirement relative to open procedure. The age of the patient, restricts its use especially in patients younger than 3 months.
