Residual Intravenous Contrast Mimicking a Ureteral Stent on Noncontrast Computed Tomography in a Patient With Ureterolithiasis.
Article in Cureus, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
This case describes a 53-year-old male patient presenting with right-sided abdominal pain and acute kidney injury (AKI) who retained intravenous (IV) contrast within the ureter from a previous image 24 hours prior at a different hospital that was initially mistaken for a calcified ureteral stent after presenting to a different hospital without the patient initially disclosing his previous hospital stay. This created diagnostic uncertainty and prompted subspecialty consultations for a device the patient had never received. The patient subsequently passed a ureteral calculus with resolution of symptoms and improvement in renal function. This case highlights the importance of recognizing residual IV contrast as a potential mimic of foreign bodies on computed tomography (CT), particularly in patients with recent contrast-enhanced studies.
