Primary leiomyosarcoma of the ureter: A case report.
Article in Oncology letters, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Malignant tumors of the smooth muscle of the ureter are extremely rare, with ~13 cases of leiomyosarcoma of the ureter being reported to date. A 59-year-old Caucasian woman presented to 'Umberto I' Hospital (Nocera Inferiore, Italy) with acute abdominal pain, predominantly in the right lumbar fossa. The patient exhibited a functional single kidney, due to left renal atrophy for a long-standing stenosis of the pyelo-ureteric joint. With the exception of this condition and hypertension (under medical therapy), the patient was in excellent clinical condition. Furthermore, the patient was not a smoker. Computed tomography indicated a stricture with a peri-ureteral soft tissue mass of 45×52 mm at the middle third of the ureter at the level of common iliac vessels. Laparoscopic excision with safety margin and a right tension free end-to-end anastomosis between the two stumps of the ureter was performed. The diagnosis of leiomyosarcoma of the right ureter was made by pathological examination. Although leiomyosarcoma is rarely noted in the urinary tract, it should be considered in the differential diagnosis of ureteral stricture disease and retroperitoneal tumors.
