Primary Nonrefluxing Megaureter: Does Ureter Diameter Really Matter?
Article in Journal of Indian Association of Pediatric Surgeons. 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
Purpose: A ureter diameter exceeding 6 mm is termed megaureter. This study aimed to evaluate the clinical features of primary non-refluxing megaureter (PNMU) and the importance of ureteral diameter in its management. Methods: Clinical, radiological, and operative findings and long-term outcomes of PNMU followed or operated on between 2011 and 2023 were evaluated retrospectively. Patients with vesicoureteral reflux, a history of lower urinary tract pathology or surgery, and a follow-up <18 months were excluded. Results: Among 32 patients (12.5% female, 87.5% male), 50% were diagnosed prenatally. Twenty-six patients had unilateral, six had bilateral megaureters. Over a mean follow-up of 94.3 ± 53.4 months, 37.5% were managed conservatively, 62.5% required intervention. Nine underwent open surgery, 11 underwent double-J-stenting. Median operation age was comparable between surgical groups ( Conclusion: Ureteral diameter has limited importance in PNMU management. Conservative management may be an option even in advanced dilatations. Postoperative ureteral dilatation may persist at varying levels and durations.
