BackgroundThere is limited research and conflicting results on the mental health and health-related quality of life of individuals surgically treated for hypospadias in childhood. Furthermore, the significance of patient-reported outcomes (PRO) in hypospadias is growing. More research is necessary on these topics, particularly in adolescents. ObjectiveWe aimed to compare mental health, health-related quality of life, body satisfaction, self-esteem, penile appearance, and sexual function outcomes in 16-year-old adolescents who had surgery for hypospadias in childhood with a healthy comparison group. Study designThe study involved 16-year-old adolescents who had surgery for hypospadias in one Norwegian hospital. An age-matched comparison group of healthy adolescents was previously recruited. The study assessed self-reported outcomes on mental health using the Strengths and Difficulties Questionnaire, health-related quality of life using the Pediatric Quality of Life Inventory, body satisfaction and self-esteem using the Self-Perception Profile for Adolescents, and genital perception and sexual function using the Pediatric Penile Perception Score and a non-validated structured interview. ResultsIn total, 117 adolescents operated for hypospadias and 61 healthy adolescents were included. The outcomes for mental health and health-related quality of life were not statistically different between groups. However, 18 (16%) hypospadias patients were classified as cases/borderline on mental health outcomes, compared to 2 (3%) in the comparison group (p=0.01). Patients classified as cases/borderline on mental health reported lower health-related quality of life, self-esteem, and more stressful life events. Self-reported penile appearance and sexual function were comparable between groups, however the proximal hypospadias group displayed lower satisfaction. DiscussionAlthough the present study had generally positive outcomes, a significant finding was that a higher number of adolescents who had previously undergone hypospadias surgery during childhood were classified as cases or borderline cases with respect to mental health issues. Hypospadias surgery in childhood may pose challenges for some patients during adolescence, particularly in the proximal group. Regular monitoring by healthcare professionals is crucial in providing necessary support. A limitation is the small size of the subgroups. ConclusionMost patients report good mental health, quality of life, and self-esteem even though patients with hypospadias report more mental health issues than the comparison group. Proximal hypospadias were less satisfied with penile appearance and sexual function. However, due to the small sample size, conclusions about this group should be treated cautiously. Assessing self-reported outcomes in follow-ups is important to identify adolescents who had hypospadias surgery and are at risk for reduced mental health.
