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: Iatrogenic ureteral injuries are challenging complications that may require complex urinary tract reconstruction. Although laparoscopic approaches have been increasingly adopted, detailed clinical outcomes of laparoscopic reconstruction for iatrogenic ureteral injuries remain limited. This study aimed to evaluate the surgical outcomes of laparoscopic urinary tract reconstruction for iatrogenic ureteral injuries at a single high-volume referral center. Methods: We conducted a retrospective single-center observational cohort study of consecutive patients who underwent laparoscopic ureteral reconstruction for iatrogenic ureteral injuries at Kameda Medical Center, Japan, between January 2012 and December 2024. Patients who underwent reconstruction for non-iatrogenic ureteral injuries or open surgery were excluded. The reconstructive procedures included ureteroneocystostomy (n=14), ureteroneocystostomy with a Boari flap (n=7), and ileal interposition using an isolated ileal segment (n=4). The perioperative outcomes, including operative time, blood loss, complications, and hospital stay, were analyzed. The long-term outcomes were assessed with respect to surgical success, which was defined as the absence of recurrent obstruction or the need for further intervention. Results: Twenty-five consecutive patients were included. The median patient age was 51 years, and 92% of the patients were female. Gynecological procedures, most commonly hysterectomies, accounted for 80% of all injuries. The median interval between injury and repair was 261 days. The median operative time was 291 min, and the median blood loss was 20 mL. None of the procedures required conversion to open surgery. Five patients experienced Clavien-Dindo grade ≥III complications. Reoperation was required in three cases (two after ileal interposition and one after Boari flap), all of which ultimately achieved successful reconstruction. Conclusions: Laparoscopic ureteral reconstruction is feasible and effective for iatrogenic ureteral injuries, with acceptable morbidity and high success rates. These results highlight the value of minimally invasive reconstructive strategies and may inform surgical decision-making in similar high-volume settings.
