Introduction:
The correction of concealed penis requires challenging surgical techniques. We describe a novel technique involving inner preputial skin substitution after degloving through a ventral approach that allows sufficient penile skin coverage and evaluated the efficacy and safety of our technique.
Methods:
From February 2009 to March 2009, 12 boys with concealed penises underwent correction via our novel technique. We administered a questionnaire about penile size, morphology, and voiding status to parents to evaluate their satisfaction with the results.
Results:
The mean age of patients at the time of operation was 4.71 ± 4.01 years, and the mean duration of follow-up was 5.11 ± 1.45 months. Parental satisfaction grades (0 to 4) concerning penile size increased from 1.00 ± 1.04 to 2.83 ± 0.94 (p = 0.002) after surgery, penile morphology from 1.00 ± 0.95 to 3.00 ± 0.85 (p = 0.001), and voiding status from 1.08 ± 1.00 to 3.33 ± 0.78 (p < 0.001) at the last follow-up visit. The parental satisfaction rates regarding postoperative changes in size and morphology were 83.3 and 91.7%, respectively. Nine parents (75%) said they would recommend the surgery to others. There were no complications, including postoperative hematoma, infection, and tissue necrosis.
Conclusion:
Our method of correcting concealed penis was demonstrated to be technically feasible and safe. It provides a good cosmetic appearance and excellent parental satisfaction ratings regarding size, morphology, and voiding function.
