The purpose of this study was to clarify association between paternity in adult hypospadias patients and reoperation for urethral obstruction after two-stage repair during childhood.METHODS:Ninety hypospadias patients who underwent the same kind of two-stage repair in our institute by a single surgeon, were initially treated at< 18 years old, and who were ≥ 18 years old during the surveywere included in the study. Present physical, social, and life status were evaluated by a mailed self-entry questionnaire, and clinical background and surgical outcome data were evaluated by medical records. National survey data of the general population were used as external control. The paternity rate of the patient groups was evaluated by Kaplan-Meier curve analysis and log-rank tests.
