ABSTRACT

Objective To compare the long-term results of hypospadias surgery and analyze the influencing factors. Methods Sixty-four hypospadiac patients were followed up, cosmetic and sexual functional results were assessed by hypospadiac patients and surgeon using a designed questionnaire and 5-item version of the international index of erectile function (IIEF-5). Selected 35 adult as normal controls. Maximum flow rate and average flow rate Were used to assess evaluation of voiding function. Results All cases were followed up for 3-11 (7.5 ± 2.3) years. The satisfaction with the long-term results of penile appearance had significant differences between hypospadiac patients and surgeon,hypospadiac patients were less satisfied than surgeon (P< 0.05 or < 0.01). No significant differences were noted between hypospadiac patients and normal controls regarding the maximum flow rate [(23.37 ±2.92), (24.41 ±2.94) ml/s], average flow rate [(16.84± 1.75), (17.34 ±2.14) ml/s] and erectile function [(22.31 ± 1.94), (22.80 ± 1.73) pointe](P> 0.05). The average penile lengths[(5.93 ± 1.06) cm] and circumferences[(6.17 ±0.83) cm] of hypospadiac patients under flaccid conditions after operation were significantly shorter than those of normal controls [ (7.38 ± 0.79 ), ( 7.53 ± 0.75 ) cm ] ( P < 0.01). The important factors to influence the results including the age at which surgery was completed, hypospadiac severity, the number of operation and complication. ConclusionsIt is useful to improve the long-term efficacy by minimizing the number of operation and complication, and treating hypospadiac patients earlier. Surgeon should pay more attention to the long-term cosmetic results of hypospadias surgery.
