Retroperitoneoscopic vs open dismembered pyeloplasty for ureteropelvic junction obstruction in children

Paediatric computer-assisted retroperitoneoscopic nephrectomy compared with open surgery

“…The success rate is similar to that of open surgery but the low number of reports might indicate that this technique remains a challenge to perform and teach [2,3].…”

606 A comparative study of pediatric open pyeloplasty, laparoscopy-assisted extracorporeal pyeloplasty and robot-assisted laparoscopic pyeloplasty

“…[8,10,11] However, the age of patients who undergo minimally invasive pyeloplasty can be even lower. It has been reported that LP is the standard treatment for UPJ obstruction in children from 3 years of age [20], and even from 4 months of age [21] in some institutions. Nevertheless, pediatric laparoscopic surgery has not been widely adopted, possibly due to its technical difficulty and long learning curve, whereas RALP is the most commonly reported robotic surgery in children.…”

A novel technique of stenting for laparoscopic pyeloplasty in children

“…In order to avoid the inconveniences of intraoperative cystoscopy, antegrade placement of a JJ stent during pyeloplasty has been popularized [6,7], and has been shown to reduce operative time [8]. Some have introduced the stent through a 14-gauge cannula [9] or a 5-mm port [10].…”

“…While the double J stent has been effective, it requires a second anesthetic for its removal in children. In addition, it is often difficult to pass the double J into the bladder in a percutaneous fashion [5,6].…”
