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

introductionApproximately 50% of all high-grade renal traumas (HGRT, American Association for the Surgery of Trauma [AAST] grade 4/5) have associated collecting system injuries. Although most of these collecting system injuries will heal spontaneously, approximately 20-30% of these injuries are managed with ureteric stents. The objective of the study was to review the management of HGRT with collecting system injuries in a level 1 trauma center.

methodsThis was a single-center, retrospective cohort study of trauma patients with HGRT and collecting system injuries from 1998-2019.

resultsWe identified 147 patients with HGRT. Of the 105 patients who had trauma computed tomography (CT) imaging within 24 hours, 46 were found to have collecting system injuries. Seven of these patients underwent intervention based on initial CT findings; the remaining 39 patients with urinary extravasation were conservatively managed. Of the 37 patients who underwent reimaging, 22 (59%) demonstrated a stable or resolving collection and 15 (41%) demonstrated continued urinary extravasation. Resolution of extravasation on subsequent imaging was observed in 10 of those patients, while five patients (14%) required intervention (four stents, one percutaneous drain) for symptoms/signs of urinary extravasation.

conclusionsIn this study, most patients with HGRT and collecting system injuries did not require intervention unless the patient became symptomatic. The majority of collecting system injuries resolved with no intervention. This study underscores the need for future prospective trials to investigate the necessity of intervening in HGRT collecting system injuries and, secondarily, the need for routine re-imaging in these asymptomatic patients.
