1 · What the graph read from it

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.

2 · The registry

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

purposeHorseshoe kidney (HSK) with ureteropelvic junction obstruction (UPJO) is a rare clinical condition. For successful pyeloplasty in these patients, preoperative anatomic mapping is crucial. Therefore, we investigated the utility of three-dimensional (3D) image reconstruction technology for accurate preoperative and intraoperative procedure planning.

methodsWe retrospectively investigated the surgical outcomes of 6 patients who underwent laparoscopic pyeloplasty (LP) for HSK-associated UPJO at our hospital between October 2017 and October 2019. Next, we examined the concordance between intraoperative findings and 3D images reconstructed with SYNAPSE VINCENT

resultsPreoperative 3D-CT imaging clearly visualized the unique anatomy of HSK, including arteries and veins, and the vessels crossing the UPJ anteriorly could be detected before surgery in 5 of 6 patients. Importantly, these images completely coincided with intraoperative findings. In fact, no intraoperative complications or conversions to open surgery were needed. Moreover, all patients are currently asymptomatic and have no major sequelae at a mean follow-up of 29.9 months (range 15.4 to 39.7).

conclusionsThe present study suggests the potential utility of 3D image reconstruction technology in performing LP through detailed preoperative mapping of complex renal anatomies, such as in HSK.
