Vaginoplasty in Male to Female transgenders: single center experience and a narrative review.

Vaginoplasty in Male to Female (M to F) transgenders is a challenging procedure, often accompanied by numerous complications. Nowadays the most commonly used technique involves inverted penile and scrotal flaps. In this paper the data of 47 M to F patients who have undergone sex affirmation surgery at the Department of Urology of the University of Trieste, Italy since 2014, using our modified vaginoplasty technique with the "Y" shaped urethral flap, have been retrospectively reviewed. Moreover, a non structured review of the literature with regards to short and long-term complications of vaginoplasty has been provided. All patients followed a standardized neo-vaginal dilation protocol. At follow up 2 patients were lost. At 12 months 88.9% of patients (40/45) were able to reach climax, 75.6% (34/45) were having neo-vaginal intercourses and median neo-vaginal depth was 11 cm (IQR 9-13.25): no statistically significant decrease in depth was found at follow up. Only one patient was dissatisfied with aesthetic appearance at 12 months. Our technique provided excellent cosmetic and functional results without severe complications (Clavien-Dindo ≥ 3). The review of the literature has highlighted the need to standardize a postoperative follow up protocol with particular regard to postoperative dilatation regimen. Further, larger randomized clinical trials are pending to draw definitive conclusions.
