Abstract

PURPOSE: We studied penile size of children who underwent hypospadias repair. Also we surveyed the degree of satisfaction with, as judged by patient's parents and urologist.
MATERIALS AND METHODS
We measured the relaxed and erected penile size of children who underwent hypospadias repair and followed more than one year (28 cases of one stage repair and 20 cases of two stage repair). All of them had no complication. We used age adjusted ANOVA test for penile size, and Wilcoxon matched pairs signed rank test for comparison of satisfaction with penile appearance between one stage group and two stage group.
RESULTS
Significant difference was noted between one stage group and two stage group for relaxed and erected penile length (p<0.05), but penile circumference was not (p>0.05). Two stage group showed statistically significant larger value than one stage group for glandular size, glandular shape, position of meatus, general appearance, and genital perception score as judged by patient's parents (p<0.05). And two stage group showed statistically larger value than one stage group for genital perception score judged by urologist (p<0.05).
CONCLUSIONS
Our study demonstrated that two stage operation met with better penile size and satisfaction judged by patient's parents and urologist than one stage operation for middle and posterior penile hypospadias.
