ABSTRACT
Introduction and Objectives: Hypospadias is the most common congenital abnormality of the penis, and is most commonly
diagnosed during the postnatal physical examination. However, milder forms of the
condition can be difficult to detect, leading to delayed referral to specialist teams.
We aim to determine whether there is an association between hypospadias and the position
of the penoscrotal raphe. Materials and Methods: A case — control study was performed where clinical photographs from children undergoing
hypospadias correction were compared with a control group of children without the
condition. The position of the penoscrotal raphe was documented as midline, left or
right. Pearson’s chi squared test was used to determine significance. Results: Images for 80 children undergoing hypospadias correction were compared with 80 normal
children in the maternity ward. 88.8% of the children with hypospadias had a penoscrotal
raphe deviated from the midline compared with only 13.8% in the control group (P < 0.0003). Conclusions: Our study demonstrates a significant association between hypospadias and deviation
of the penoscrotal raphe from the midline. Consideration should be given to whether
to include this finding within the spectrum of abnormalities seen in hypospadias.
Examination of the penoscrotal raphe is simple to perform and could aid in the early
diagnosis in children with milder forms of the condition.
