Comprehensive evaluation of vaginal intraepithelial neoplasia development after hysterectomy: insights into diagnosis and treatment strategies.

Vaginal intraepithelial neoplasia (VaIN), a precancerous lesion associated with human papillomavirus (HPV), impacts women's health and quality of life. However, the natural progression of VaIN after hysterectomy remains uncertain, due to its low incidence. The existing literature predominantly consists of single-center retrospective studies lacking robust evidence-based medicine. The management of VaIN after hysterectomy is diverse and controversial, lacking a consensus on the optimal approach. Therefore, it is imperative to investigate the development of VaIN after hysterectomy, emphasizing the importance of accurate diagnosis and effective management strategies.
