Optimizing neourethral coverage in urethroplasty for hypospadias with tunica vaginalis versus dartos fascia: A systematic review and meta-analysis.
Article in Tzu chi medical journal. 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
Objectives: Hypospadias repair requires second-layer coverage to minimize complications. This study compares tunica vaginalis flap (TVF) and dartos fascia (DF) as second-layer materials in tubularized incised plate (TIP) urethroplasty, focusing on postoperative complications, functional outcomes, and cosmetic results to determine the superior option. Materials and Methods: Comparative studies on TVF versus DF in TIP urethroplasty were identified through five databases (PubMed, Scopus, ScienceDirect, Cochrane Library, and Google Scholar; January 2015-January 2025). A modified PICO framework guided the search, and risk of bias (RoB) was assessed using RoB 2 and ROBINS-I. Meta-analysis evaluated postoperative complications. Results: Ten studies comparing TVF and DF in TIP hypospadias repair were included in the study. TVF significantly reduced the risk of urethrocutaneous fistula (UCF) (risk ratios [RR] = 0.27; 95% confidence interval [CI]: 0.16-0.46; Conclusion: Findings from this meta-analysis suggest that the tunica vaginalis flap may be associated with lower rates of selected postoperative complications, particularly UCF, wound infection, wound dehiscence, and penile skin necrosis, compared with dartos fascia in TIP hypospadias repair, whereas cosmetic and functional outcomes appear comparable between the two techniques.
