In brief
This study developed and tested a novel multi-layered biocompatible dressing for pediatric hypospadias repair using a rat wound model. The new dressing demonstrated superior absorption, ease of removal, and wound healing with reduced inflammation compared to standard gauze dressing, suggesting potential clinical benefits for postoperative hypospadias care.

Abstract
Purpose
The search for an ideal Hypospadias repair dressing continues. We aimed to develop a hypoallergenic optimized biocompatible dressing (BD).
Method
BD with a multi-layered structure of hydrophilic treated Polypropylene with three-layered technologies; Absorbent-spunlaced hydroentangled polyester/viscose blend, outer Polypropylene, Polyester, Acrylic, and Spandex, with super Absorbent Polymer and Acrylic adhesive. Wistar rat abdominal wound model was divided into two groups: control (normal gauze dressing with adhesive) and Study (BD). The physical properties and wound characteristics were compared.
Results
Average mass: thickness of BD was 626.7 ± 5.6 g m−2: 2.6 ± 0.015 mm. Absorption was 1425.2 ± 127.6%. Percentage desorption of solution A from dressings at 24:40 h was 1249 ± 150%:1417 ± 230%. BD was hydrophilic with no particles/residue after immersion and pH neutral. The average air permeability was 11.6 ± 1.6 cm3/cm2/sec. The tensile force was 200N–220N with an extension on the breaking point at 24 mm. BD was superior for ease of removability on Day 6 (p = 0.012) and sticking quality (p = 0.036), absorption (p = 0.036), ease of removability(p = 0.036), and sustenance (p = 0.030) on Day 10. BD dressing demonstrated better wound healing (p = 0.015) and decreased redness (p = 0.002) on Day 10. Histopathological healing was better with BD on Day 14(p = 0.025) and Day 20 (p = 0.034).
Conclusion
BD demonstrated better desirable physical and wound healing qualities with less inflammation compared with control normal dressing.
