Transabdominal approach laparoscopic ureteral reimplantation at the top of the bladder for the treatment of primary obstructive megaureter.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Congenital primary obstructive megaureter (POM) is characterized by distal ureteral obstruction, leading to ureteral dilation, hydronephrosis, and potential renal impairment. Surgical intervention is necessary for severe hydronephrosis (SFU grade III-IV) or progressive renal decline. Open ureteral reimplantation is the standard treatment but is associated with significant surgical trauma and prolonged recovery. This study evaluates the safety and efficacy of transabdominal laparoscopic ureteral reimplantation (TALUR) at the posterior wall-bladder dome and compares its outcomes with the Politano procedure. Methods: This retrospective, single-center study included pediatric POM patients who underwent ureteral reimplantation at the Affiliated Hospital of Zunyi Medical University from October 2019 to December 2023. Patients were assigned to the TALUR group ( Results: All procedures were successfully completed without conversion to open surgery. The TALUR group had a significantly shorter operative time (76.5 ± 12.6 min) compared to the Politano group (95.7 ± 14.8 min, Conclusion: TALUR is a safe and effective minimally invasive technique for pediatric POM. Compared to the Politano procedure, TALUR offers shorter operative time, faster recovery, and comparable efficacy. Further large-scale studies are required to confirm its long-term effectiveness.
