Comparison of Penile Appearance and Outcomes Between Prefabricated Urethra and Pre-implanted Urethral Plate for Treatment of Children With Severe Hypospadias: A Retrospective Study

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.

Fasciocutaneous foreskin twin flaps in hypospadias repair: Reconstructing a functional penis with freestyle design

BACKGROUND

Hypospadias is the most common congenital urological deformity in males; however, there is still no perfect solution or surgical method for one-stage operations to fix proximal hypospadias with ventral penile curvature (VPC). We developed a fasciocutaneous foreskin twin flap technique that can provide freestyle flap designs in hypospadias repair.

METHODS

A retrospective study including 26 patients was performed between January 2017 and June 2020. The surgical procedures included VPC correction, skin flap design, transfer and reconstruction. The urethra and shaft were reconstructed by twin flaps in one stage. All patients were followed up until 12 months.

RESULTS

All VPC cases were corrected after the operation. The fistula rate was 11.5% (3/26). No meatal stenosis, urethral diverticulum, or stricture was observed. A total of 92.3% (24/26) of patients were satisfied with their penis appearance.

CONCLUSIONS

The fasciocutaneous foreskin twin flaps provide freestyle designs in hypospadias repair, which can achieve a one-stage operation for proximal hypospadias with low fistula rates.
