The Role of Postoperative Dressing in Hypospadias Surgery: A Systematic Review and Meta-analysis of the Pediatric Literature

This study aimed to describe the available dressings and their management in patients undergoing hypospadias repair and compare postoperative outcomes with and without dressing and between the different dressing types. A comprehensive electronic literature search of PubMed, Embase, and Cochrane Library was conducted to obtain studies, published in the period 1990 to 2021, reporting on the dressing used following hypospadias surgery. All information regarding the dressing was considered as primary endpoints, whereas surgical outcomes were assessed as secondary outcomes. Thirty-one studies containing 1,790 subjects undergoing hypospadias repair were included. Dressings were divided into three categories: nonadherent to the wound, adherent to the wound, and glue-based dressings. Most authors preferred to remove/change the dressing in the ward and the median time of removal/change was 6.56 postoperative days. The dressing removal appeared as the most frequent factor generating parental anxiety. The median rate of wound-related complications was 8.18%, of urethroplasty complications 9.08% and of reoperations 8.18%. Meta-analysis of outcomes showed higher risk of reoperations using conventional dressing, with no differences in urethroplasty and wound-related complications rates between conventional and glue-based dressings. Furthermore, the use of dressing reported increased risk of wound-related complications compared with no dressing, without significant differences regarding occurrence of urethroplasty complications and reoperations. The current evidence confirmed that there is no difference in outcomes of hypospadias repair depending on a certain dressing type. To date, surgeon's preference remains the main factor determining the choice for a specific dressing or for no dressing at all.

Current perspectives in hypospadias research: A scoping review of articles published in 2021 (Review)

Hundreds of papers are written about hypospadias every year referring to all aspects of the pathology, being one of the most common congenital malformations. The present study conducted a scoping review of articles published in 2021 to present the main issues and summarize current perspectives and achievements in the field. It searched for the keyword 'hypospadias' in the three most popular databases (PubMed, Scopus and Web of Science). After the analysis of the publications, they were categorized into different domains. The present review was performed respecting the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA ScR) guidelines. A total of 284 articles were included. These were published in 142 different journals. The most accessed was the Journal of Paediatric Urology with 54 articles. The main identified domains were related to surgical techniques, postoperative care, complications, anesthesia, anatomical factors, genetics, environmental factors, endocrinology, associated malformations, questionnaires and recommendations, management, biological materials, animal models, retrospective studies of centers, social media, bibliometrics, small gestational age, neoplasm, or fertility. Promising modifications of existing surgical techniques were presented with improved outcomes for both the proximal and distal types of hypospadias. Relevant anatomical and etiological, and also genetic factors were clarified. Aspects of the peri- and postoperative management referring to the antibiotherapy, analgesia, dressing techniques, and the future use of novel bioengineering agents to prevent, reduce or treat the occurring complications were discussed.
