Transgender women, who were scheduled for GAS, participated in the study. The volunteers were submitted to a clinical evaluation of the PFM followed by digital palpation (PERFECT method) and electromyography in the preoperative, 15, and 30 days after GAS. They responded to the International Consultation on Incontinence Questionnaire\u2010Urinary Incontinence (UI)\u2014Short Form to evaluate the effect of UI on quality of life and to questions related to the urinary, anorectal, and sexual symptoms.
