Application of Transperineal and Transabdominal Ultrasonography in the Repair of Distal Vaginal Atresia: A Report of Three Cases.

Distal vaginal atresia is one of the rare Mullerian anomalies and may often be misdiagnosed as an imperforate hymen. This paper reports pre-operative and intra-operative use of ultrasonography in three patients with distal vaginal atresia. Two patients underwent pull-through surgery and in the other patient, a neovagina was formed using skin graft as the proximal vagina was found to be insufficient for a pull-through vaginoplasty. Pre-operative transperineal ultrasonography and intra-operative transabdominal ultrasonography may prove to be useful in surgical planning and choosing the proper surgical procedure. It also helps prevent damage to adjacent tissues. [ABSTRACT FROM AUTHOR]
