The Montréal Classification of urethral lengthening for phalloplasty in transmasculine patients-surgical techniques and urethral complications.

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.
