INTRODUCTION: Phalloplasties are one of the most performed genital surgeries in the treatment of gender dysphoria for transmasculine patients. Urethral lengthening is an essential component of phalloplasties. Few techniques have been described for the creation of this pars fixa urethra. The purpose of this article is to present the Montréal Classification for pars fixa urethral lengthening, to detail the surgical techniques and to report on clinical outcomes.
MATERIALS AND METHODS: All patients undergoing phalloplasty from November 2016 to February 2019 were included in this study. Patient demographics, type of surgery and urological complications were recorded. Statistics were performed using student's T-test, Chi-squared test, Fisher's exact test and One-way ANOVA. Patients underwent either type 1, type 2, or type 3 urethral reconstruction.
RESULTS: Of the 84 total patients, 45 underwent type 1 lengthening, 28 type 2, and 11 type 3. Eighteen and 33 patients underwent single-stage and two stage anastomosis of the pars fixa to the pars pendulans neourethra, respectively. Thirty-three patients have not had any additional surgeries to date. Post-operative urological complications for immediate anastomosis and two-stage anastomosis were reported in 77.7% and 18.2% of patients, respectively.
CONCLUSIONS: We propose a classification as well as a description of three types of urethral lengthening techniques. Over the last few years, we have shifted away from single-stage anastomosis and have adopted a two-stage anastomosis technique. Our experience allows us to classify urethral lengthening and to standardize care depending on patient characteristics, leading to excellent results.
