High-Grade Urothelial Carcinoma Arising From a Ureteral Diverticulum: A Rare Case Report.

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: Ureteral diverticula are rare urological anomalies characterized by outpouchings of the ureteral wall. Malignancy arising from these structures is exceptionally rare, with only a few cases reported. Case Presentation: We report a 57-year-old male with high-grade urothelial carcinoma arising from a ureteral diverticulum in the left distal ureter. The patient experienced painless gross hematuria, and computed tomography revealed a 3 cm undetermined mass near the left distal ureter. Multiple endoscopic diagnostic procedures were inconclusive, with the final diagnosis confirmed intraoperatively. The surgery involved resection of the mass, and intraoperative frozen section analysis revealed high-grade urothelial carcinoma. A segmental ureteral resection was performed with reconstruction using a Boari flap and Psoas hitch. Final histopathology confirmed locally advanced, high-grade pT3 urothelial carcinoma, and adjuvant chemotherapy was recommended. Conclusion: This case underscores the diagnostic and management challenges of upper tract urothelial carcinoma, especially in rare cases involving ureteral diverticula.
