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

objectiveTo report a case of pediatric bladder urothelial carcinoma treated with transurethral thulium laser resection and, based on a literature review, to discuss its clinical characteristics, diagnostic considerations, and surgical strategies adapted to the unique anatomy of the pediatric urethra.

methodsThe clinical data of a child with bladder urothelial carcinoma admitted to the Second Department of Urology, The First Affiliated Hospital of Kunming Medical University in October 2024 were retrospectively analyzed.

resultA 9-year-old boy presented with transient, painless gross hematuria as the primary clinical manifestation. Bladder tumor was diagnosed via imaging. He subsequently underwent transurethral thulium laser resection of the bladder tumor via ureteroscopy under general anesthesia. The procedure was successful, and immediate postoperative intravesical chemotherapy was administered. Histopathological examination confirmed low-grade papillary urothelial carcinoma of the bladder. The patient has since received regular postoperative intravesical chemotherapy. Follow-up at one year showed no evidence of tumor recurrence on ultrasound.

conclusionBladder urothelial carcinoma is exceedingly rare in children. Raising awareness and vigilance among healthcare providers and families is essential for early diagnosis. In cases where standard adult instruments are unsuitable, transurethral thulium laser resection via a ureterorenoscope represents a safe and feasible adaptive technique for pediatric low-grade non-muscle-invasive urothelial carcinoma. This report offers a practical reference for the management of such rare cases.
