Preoperative Diagnosis of Bladder Paraganglioma Followed by Robot-Assisted Partial Cystectomy: A Case Report.
Article in IJU case reports, 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
Introduction: Bladder paraganglioma is a rare neuroendocrine tumor for which accurate preoperative diagnosis is important because tumor manipulation may provoke catecholamine-related hemodynamic instability. Case Presentation: A 58-year-old man presented with hematuria. Cystoscopy revealed a submucosal bladder tumor. Contrast-enhanced computed tomography and magnetic resonance imaging demonstrated a 2-cm bladder wall mass with characteristic findings suggestive of paraganglioma. Although catecholamine levels were within normal limits and no adrenergic symptoms were present, metaiodobenzylguanidine scintigraphy showed uptake in the lesion, supporting the diagnosis. To avoid the potential risk associated with TUR, preoperative alpha-adrenergic blockade with doxazosin was administered, followed by robot-assisted partial cystectomy. No significant intraoperative hemodynamic instability occurred. Histopathological examination confirmed paraganglioma. Conclusion: Recognition of characteristic imaging findings may facilitate preoperative diagnosis and safe surgical management of bladder paraganglioma. Robot-assisted partial cystectomy was a feasible minimally invasive treatment option.
