OBJECTIVES: To study the clinical, cytological, and vaginal microbiota findings in patients with Mayer-Rokitansky-Küster-Hauser syndrome who underwent neovaginoplasty using Nile tilapia fish skin.
METHODS: This is a cross-sectional study with 7 cisgender women with Mayer-Rokitansky-Küster-Hauser syndrome who had previously undergone neovagina reconstruction using Nile tilapia fish skin at a university hospital. Local institutional review board approval and written permission from the patient were obtained. Between August 2019 and November 2021, within 12 to 24 months after surgery, vaginal specimens were obtained for conventional oncotic and hormonal cytology, and for Gram staining. The Nugent scores were calculated. Colposcopy was also performed.
RESULTS: Squamous cells without atypia were found in all patients. Five patients had intermediate vaginal microbiota (Nugent score of 4), which was determined by the presence of few lactobacilli on Gram staining. In hormonal cytology, 4 patients presented with findings compatible with menacme. No colposcopic change was observed. When postsurgical dilation was performed correctly, a mean vaginal length of 8.3 cm was maintained after 1 year of follow-up.
CONCLUSIONS: Squamous cells without atypia were present in neovaginas with Nile tilapia fish skin. Most vaginal contents revealed intermediate microbiota and hormonal results compatible with menacme. Studies with a greater number of patients are necessary for a more comprehensive understanding of the microbiome in neovaginas with this new technique, thereby providing support for the treatment and prevention of associated pathologies.
