ABSTRACT
The authors describe the technique of robotic vaginectomy, anterior vaginal flap urethroplasty, and use of a longitudinally split pedicled gracilis muscle flap to recreate the bulbar urethra and help fill the vaginal defect in female-to-male gender-affirming phalloplasty. Vaginectomy is performed by means of the robotically assisted laparoscopic transabdominal approach. Concurrently, gracilis muscle is harvested and passed through a tunnel between the groin and the vaginal cavity. It is then split longitudinally, and the inferior half is passed into the vaginal cavity; it is inset into the vaginal cavity. Following urethroplasty, the superior half of the gracilis flap is placed around the vaginal flap to buttress this suture line with well-vascularized tissue. From May of 2016 to March of 2018, 16 patients underwent this procedure. The average age of the patients was 35.1 ± 8.8 years, average body mass index was 31.4 ± 5.5 kg/m, and average American Society of Anesthesiologists class was 1.8 ± 0.6. The average length of surgery was 423.6 ± 84.6 minutes, with an estimated blood loss of 246.9 ± 84.9 ml. Patients were generally out of bed on postoperative day 1, ambulating on postoperative day 2, and discharged to home on postoperative day 3 (average day of discharge, 3.4 ± 1.4 days). At a mean follow-up time of 361.1 ± 175.5 days, no patients developed urinary fistula at the urethroplasty site. The authors' use of the longitudinally split gracilis muscle in first-stage phalloplasty represents a novel approach to providing well-vascularized tissue to achieve both urethral support and closure of intrapelvic dead space, with a single flap, in a safe, efficient, and reproducible manner. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, IV.
