Objective: To investigate the role of MRI in the evaluation of both the new female anatomy and complications in male-to-female sex reassignment surgery (MtF-SRS). Methods: 71 consecutive patients with MtF-SRS had 74 MRI [age range, 21-63 years; mean (±standard deviation) age, 36 ± 10 years; median age, 37 years]. In 47 patients, MRI was performed to rule out early post-operative complications after gender conversion (n = 40), vaginoplasty (n = 6) or remodelling of the labia majora (n = 1). In 27 patients, MRI was performed 1-20 years after MtF-SRS for late post-operative complications, pain or dysuria, inflammatory changes or poor cosmetic outcome. Three patients had MRI both before and after the operation. Results: MRI allowed investigation of the new female anatomy in all cases. Soon after MtF-SRS, a small amount of blood was identified in all patients around the neoclitoris, urethral plaque and labia. Post-operative complications were clinically significant fluid collections (n = 5), labial abscesses (n = 2), severe cellulitis (n = 3), partial neovaginal prolapse (n = 3), focal necrosis and dehiscence of the vaginal wall (n = 2) and hypovascularization of the neoclitoris (n = 1). After ileal vaginoplasty, three patients developed clinically insignificant haematomas, one a large rectovaginal fistula with dehiscence of the intestinal anastomosis and bowel perforation (n = 1). In the 27 patients investigated 1-20 years after MfF-SRS, MRI demonstrated cavernosal remnants (n = 10), spared testis (n = 1) neovaginal strictures (n = 8), fistulas and abscesses (n = 3) and prolapse (n = 2). Three of these patients also had fibrotic changes. In the remaining three patients, no pathological features were identified. Conclusion: After genital reconfiguration, MRI allows assessment of the post-operative anatomy and of post-operative complications. Advances in knowledge: Imaging features of the new anatomy and of surgical complications after SRS are discussed and illustrated.

Abstract

Objective: To investigate the role of MRI in the evaluation of both the new female anatomy and complications in male-to-female sex reassignment surgery (MtF-SRS). Methods: 71 consecutive patients with MtF-SRS had 74 MRI [age range, 21-63 years; mean (±standard deviation) age, 36 ± 10 years; median age, 37 years]. In 47 patients, MRI was performed to rule out early post-operative complications after gender conversion (n = 40), vaginoplasty (n = 6) or remodelling of the labia majora (n = 1). In 27 patients, MRI was performed 1-20 years after MtF-SRS for late post-operative complications, pain or dysuria, inflammatory changes or poor cosmetic outcome. Three patients had MRI both before and after the operation. Results: MRI allowed investigation of the new female anatomy in all cases. Soon after MtF-SRS, a small amount of blood was identified in all patients around the neoclitoris, urethral plaque and labia. Post-operative complications were clinically significant fluid collections (n = 5), labial abscesses (n = 2), severe cellulitis (n = 3), partial neovaginal prolapse (n = 3), focal necrosis and dehiscence of the vaginal wall (n = 2) and hypovascularization of the neoclitoris (n = 1). After ileal vaginoplasty, three patients developed clinically insignificant haematomas, one a large rectovaginal fistula with dehiscence of the intestinal anastomosis and bowel perforation (n = 1). In the 27 patients investigated 1-20 years after MfF-SRS, MRI demonstrated cavernosal remnants (n = 10), spared testis (n = 1) neovaginal strictures (n = 8), fistulas and abscesses (n = 3) and prolapse (n = 2). Three of these patients also had fibrotic changes. In the remaining three patients, no pathological features were identified. Conclusion: After genital reconfiguration, MRI allows assessment of the post-operative anatomy and of post-operative complications. Advances in knowledge: Imaging features of the new anatomy and of surgical complications after SRS are discussed and illustrated.
