Abstract

Background:  Müllerian dysgenesis occurs in approximately 1 in 5000 live-born females. There have been many methods described for creation of a functionally useful vagina in cases of Müllerian dysgenesis. Given the number of available methods and the infrequency of the condition, outcome data can be difficult to obtain.

Aim:  To perform a retrospective review of presentation, treatment and outcomes in cases of Müllerian dysgenesis seen at the adolescent gynaecology unit at the Royal Hospital for Women, Sydney.

Methods:  Thirty women with Müllerian dysgenesis were identified between January 2000 and December 2004. Of these, 23 had Müllerian agenesis and seven had partial vaginal agenesis. As this audit and review conform with the standards established by the National Health and Medical Research Council for ethical quality review, ethics approval was not sought.

Results:  Dilator therapy under the guidance of a trained clinical nurse educator was successful in creating a functionally useful vagina and was well tolerated in all cases of Müllerian agenesis. Patients suffering from segmental vaginal agenesis all had surgical creation of a neovagina with the aid of an amnion vaginoplasty. All patients who were referred following surgical drainage of their haematocolpos outside the unit became infected and needed to undergo further surgery prior to creation of a neovagina. Fibrotic vaginal bands developed only in these patients.

Conclusion:  The outcomes reinforce the TASPAG guidelines of management for Müllerian dysgenesis, which suggest that dilators are generally effective in creating a functionally useful vagina, and if surgery is required, the primary operation should be definitive and performed by well-trained experts.
