Open surgical dismembered pyeloplasty has traditionally been the preferred method for treating ureteropelvic junction obstruction (UPJO), with a success rate exceeding 94%. However, it is associated with drawbacks such as increased postoperative pain, extended hospital stays, and visible scarring. Minimally invasive alternatives, including laparoscopic pyeloplasty (LP) and robot-assisted laparoscopic pyeloplasty (RALP), have gained popularity since their introduction in 1993, offering comparable success rates to open surgery while providing cosmetic benefits and shorter hospital stays. Nevertheless, these techniques present challenges in pediatric patients, including limited working space, technical complexities, and prolonged operative times. The retroperitoneoscopic one-trocar-assisted pyeloplasty (OTAP) method, introduced in 2007, combines the advantages of minimally invasive surgery with the success rates of standard dismembered pyeloplasty. Despite favorable outcomes reported by several researchers, comprehensive studies regarding long-term follow-up and clinical outcomes are lacking. This study aims to evaluate the long-term outcomes of OTAP, addressing this gap in the medical literature.
