Abstract

Introduction: Differences of sex development (DSD) are congenital conditions in which there is atypical chromosomal, gonadal and/or phenotypic sex. A phenotype of severe genital atypia in patients raised as male is a relatively rare occurrence and standards for management are lacking. Decision making for early surgical planning in these rare cases includes, but is not limited to, degree of atypia, location of testes, and presence of Mϋllerian remnants. In this study we describe surgical approaches and short-term outcomes for masculinizing genitoplasty in moderate to severe genital atypia in young patients raised male, for whom parents opted for early surgery. Methods: This NIH-sponsored study is an ongoing, observational, multicenter investigation assessing medical, surgical and psychological outcomes in children and their parents affected by atypical genitalia due to DSD. Participants were prospectively enrolled from 12 children's hospitals across the United States that specialize in DSD care. Criteria for child enrollment were a Quigley score of 3–6 in those with a 46, XY or 45,X/46, XY chromosome complement, age <3 years with no previous genitoplasty; patients were included independent of whether genitoplasty was performed. Cosmesis was graded according to a 4-point Likert scale and complications per the Clavian-Dindo classification. Results: Of the 31 participants, 30 underwent hypospadias repair and 1 patient did not undergo a genitoplasty procedure. The majority of participants (22) received a staged hypospadias repair. Seventeen complications were identified in 12 of the 31 children (41%) at 12 months of follow up. Glans dehiscence and urethrocutaneous fistula were the most common complications. Orchiopexy was performed in 14 (44%) and streak gonads were removed in 4 (13%) participants. Both parents and surgeons reported improved cosmesis after surgery when compared to baseline. Conclusion: Genitoplasty was chosen by parents for the majority of children eligible for study. No single surgical approach for masculinizing moderate to severe genital ambiguity in young patients with 46, XY or 45,X/46, XY DSD was adopted by all surgeons. Complications occurred in 41% of those who underwent genitoplasty for severe hypospadias. Overall, appearance of the genitals, as determined by parents and surgeons, improved following genitoplasty. Outcomes of early genitoplasty are needed to guide families when making decisions about such procedures for their young children.[Formula presented]
