Radiological evaluation of vaginal width and depth in male-to-female transsexuals by the use of magnetic resonance imaging.
Nowadays, the surgical treatment of male-to-female transsexuals is not rare, but few studies have reported on postoperative results. The aim of this study was to determine the role of magnetic resonance imaging (MRI) in the evaluation of the results of sex reassignment surgery (SRS) in male-to-female transsexual patients. Ten such patients (median age 28 years, range 21-47), who had undergone SRS using an inversion of combined penile and scrotal skin flaps for vaginoplasty, were examined with MRI after the operation. Turbo spin-echo T2-weighted and spin-echo T1-weighted images were obtained on sagittal, coronal, and axial planes with a 1.5 T superconducting magnet. The images were acquired on the sagittal, coronal and axial planes, by using TSE T2 weighted and SG T1 weighted images. MRI was performed within 2 weeks after the operation in six patients and after 1 year in the other four. In all cases, the images were obtained with and without an inflatable silicon vaginal tutor. The average neovaginal depth was 7.9 cm (range 6-10 cm). In four patients, MRI showed the presence of cavernosal rests, and in two there were remnants of the corpus spongiosus. In another patient, an abnormal anterior inclination of the neovagina was present. The average distance of the recto-vaginal septum was 4 mm (range 3-6 mm). No major complications were noted. Our study allowed not only a detailed assessment of the pelvic anatomy after genital reconfiguration, but also provided valuable information on possible complications.
