Postoperative complications of male to female sex reassignment surgery: A 10-year French retrospective study

Summary In primary male to female (MTF) sex reassignment surgery (SRS), the most frequent postoperative functional complications using the penoscrotal skin technique remain neovaginal stenosis, urinary meatal stenosis and secondary revision surgery. We aimed to retrospectively analyze postoperative functional and anatomical complications, as well as secondary procedures required after MTF SRS by penile skin inversion. All patients operated on for MTF SRS, using the inverted technique, from June 2006 to July 2016, were retrospectively reviewed. The minimum follow-up was one year (five-years maximum follow-up). Soft postoperative dilationprotocol was prescribed until complete healing of the vagina. We did not prescribe long-term hard dilation systematically. Possible short-depth neovaginas were primarily treated with further temporary dilation using a hard bougie. Among the 189 included patients, we reported a 2.6% of rectovaginal wall perforations. In 37% of patients we had repeated compressive dressings and 15% of them required blood transfusions. Eighteen percent of patients presented with hematoma and 27% with early infectious complications. Delayed short-depth neovagina occurred in 21% of patients, requiring additional hard dilatation, with a 95.5% success rate. Total secondary vaginoplasty rate was 6.3% (4.7% skin graft and 3.7% bowel plasty). Secondary functional meatoplasty occurred in 1% of cases. Other secondary cosmetic surgery rates ranged between 3 to 20%. A low rate of secondary functional meatoplasty was showed after MTF SRS by penile skin inversion. Hard dilation was prescribed in case of healed short-depth vagina, with good efficiency in most of cases. Secondary vaginoplasty was required in cases of neovagina stenosis or persisting short-depth neovagina after failure of hard dilation protocol.
