OBJECTIVE: To define the appropriate penile straightening procedures corresponding to the specific penile curvature by comparing the penile length resulting from various straightening procedures in hypospadias repair.
METHODS: We retrospectively analyzed hypospadias patients between 2017 and 2019. Patients were divided into three groups based on the penile curvature after degloving: <30°, 30°-45°, and >45°. The penile straightening procedures include dorsal plication (DP), simple urethral plate (UP) transection, and UP transection with ventral lengthening (VL). The paired t-test was conducted for the penile length after fully straightening in each group, simultaneously calculating the length changes (∆T). In addition, the penile length changes among these procedures were compared using Spearman analysis to show the correlation between the penile curvature and the length.
RESULTS: The penile length changed significantly after fully straightening in all groups. The length decreased mildly after DP, while increased in the other procedures. The penile curvature after degloving was positively correlated with the absolute change in the penile length (P < 0.001, r = 0.424) and the ratio of ∆T in the original length (P < 0.001, r = 0.433).
CONCLUSION: For hypospadias, the 30° after degloving may serve as the cut-off for the selection of the straightening method from the perspective of the penile length. For those with < 30°, methods such as DP or UP transection can either be selected. In patients with > 30°, DP should be used with caution because of the potential risk to shorten the penis. In contrast, UP transection effectively corrects the penile curvature and increases the penile length concurrently, which should be primarily recommended in those patients.
