Neovaginoplasty Using Sigmoid Colon in Patient with Male Pseudo-hermaphroditism / 대한비뇨기과학회지

ABSTRACT

Gender assignment is the most important step in treating a child with ambiguous genitalia. Once an appropriate sex assignment has been made, the next critical step is the performance of a reconstructive procedure in a timely fashion. The aim of vaginoplasty should be the creation of a neovagina that will have a satisfying appearance, function and feeling, with a low rate of morbidity. Different forms of vaginal reconstruction have been described, and include the use of split-thickness or full-thickness grafts, amnion, peritoneum or bowel. Of these, vaginal reconstruction, with isolated bowel segments, provides a cosmetic, self-lubricating neovagina, with low rates of failure and revision, and without the need for routine dilation. Sigmoid vaginoplasty especially seems to have a clear advantage, with an excellent surgical success rate, and low complication rates. We report our initial experience of a neovaginoplasty, using sigmoid colon, in a 10-year old patient with an incomplete form of androgen insensitivity syndrome (Reifenstein syndrome).
