The application of confocal endomicroscopy to the uterine cervix emerges as a promising alternative to weekly cervical examinations in the follow-up of patients who have undergone uterus transplantation. The authors report the case of a 34-year-old woman with Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome, diagnosed at 15 years of age, who in August 2026 underwent the first successful live-donor uterus transplantation performed in Latin America. The surgical procedure was uneventful. The confocal endomicroscopy of the uterine cervix was employed to evaluate its potential utility in identifying inflammatory changes that might precede graft rejection. No irregular or distorted epithelium or severe inflammation was observed, and this finding was confirmed by biopsies and histological analysis.
