Right ureterovesical junction cyst associated with ipsilateral renal agenesis: a case report of a possible Wolffian duct maldevelopment.
Article in Frontiers in medicine, 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: Right ureterovesical junction cyst associated with ipsilateral renal agenesis is an extremely rare congenital anomaly of the male genitourinary tract, likely resulting from abnormal development of the Wolffian duct and ureteric bud. We report the case of a 35-year-old man with a one-year history of progressive dysuria. Contrast-enhanced computed tomography (CT) revealed right renal agenesis and cystic dilatation of the intramural segment of the right ureter protruding into the bladder cavity, with the proximal ureter showing tortuosity and atresia. The contralateral kidney and ureter were normal. The patient underwent laparoscopic right ureterectomy combined with transurethral bladder exploration and left ureteral stent placement. Histopathological examination confirmed a ureterovesical junction cyst with chronic inflammation and cystic wall change. The postoperative course was uneventful. Conclusion: This case highlights a rare Wolffian duct-related developmental anomaly distinct from classical Zinner syndrome, emphasizing the importance of recognizing atypical presentations for accurate diagnosis and optimal surgical management.
