RESUMO
OBJECTIVE: To investigate whether the panoramic view offered by robot-assisted laparoscopic pyeloplasty (RALP) reduces the likelihood of missing a crossing vessel compared to open pyeloplasty in cases where initial pyeloplasty fails. METHODS: A single institution redo-pyeloplasty database was reviewed for children treated between January 2012 to July 2023. Clinical history, imaging and operative details were reviewed to identify the etiology for the redo procedure. RESULTS: Cohort consisted of 45 patients undergoing a redo RALP during the study period. 29 of 45 patients had an initial open surgical approach, whereas 16 had an initial RALP. 10 patients were noted to have a missed crossing vessel on redo pyeloplasty - 9 had an initial open approach whereas 1 had an initial RALP (p<0.0001). CONCLUSIONS: RALP may reduce the risk of missing a crossing vessel due to the panoramic view of the surgical field intrinsic to an intraperitoneal RALP approach.

Fibroepithelial polyps in the urinary tract are a rare cause of obstructive uropathy with fewer than 130 cases reported in the literature. In our series, we describe polyps that were missed on preoperative imaging and later found in the operating room during pyeloplasty. It is critical for urologists to be aware of polyps as a potential source of obstruction as they can increase the complexity of a reconstruction and, if missed, may result in a failed repair and persistent obstruction. We hypothesize that performing a retrograde pyelogram prior to ureteric reconstruction will facilitate diagnosis prior to surgical repair.
RESUMO
PURPOSE OF REVIEW: This review aims to provide an in-depth exploration of the recent advancements in robot-assisted laparoscopic pyeloplasty (RALP) and its evolving landscape in the context of infant pyeloplasty, complex genitourinary (GU) anatomy, recurrent ureteropelvic junction (UPJ) obstruction, cost considerations, and the learning curve. RECENT FINDINGS: Recent literature highlights the safety and efficacy of RALP in treating the infant population, patients with complex GU anomalies, and recurrent UPJO which were all traditionally managed using the open approach. Cost considerations are evolving, with the potential for RALP to have a lesser financial burden. In addition, the learning curve for RALP is diminishing due to robust training programs and advances in research. RALP has become the gold standard in the treatment of UPJO in pediatric urology at many children's hospitals. Surgeon comfort and research in this space allow safe and successful reconstruction in the most challenging of cases.
