Vaginal anomaly is a congenital deformity of female genital organs. The most renowned example is MRKH syndrome. In most cases, surgical treatment is required and its approach is very diverse. Case 1 : 13 year old who has not had menarch came to visit due to lower abdominal pain. Abdominal CT showed hematocolposis due to imperforated hymen and bilateral hydrosalpinx and Lt. ureteral duplication. External organs showed no vaginal orifice nor lower vagina, and hematocolposis and upper vagina were visible on incision of the blockage. Laparoscopy showed normal uterus, both ovaries and fallopian tubes, and a vaginal reconstruction was attempted through vaginoplasty. Case 2 : 18 year old came to visit due to absence of menarche. The breast development was at the age of 12, development of body hair at that of age 13. Radiologic images implied double uterus or bicornuated uterus, and did not show uterine cervix nor vagina. The external organ had vaginal oriface but soon reached blockage shortly after 1cm of entry. Laparoscopy showed normal bilateral ovaries and uterus, but could not clearly observe the normal uterus body or cervix. There were only traces of uterus with V-shape rudimentary horn shape. Case 3 : 13 year old patient came to visit due to irregular menstrual cycle since menarch which happened. Radiologic images suggested double uterus, and hematocolposis due to large hematoma in vagina. The patient experienced excess amount of old blood each menstrual cycle, and a decrease in size of hematoma after menstrual cycle was observed. Laparoscopy showed double uterus, and both ovaries and fallopian tubes were normal. From vaginal approach, vagina was divided into two compartments based on incomplete septum, forming hematoma pocket on the anterior side. Incomplete septum was in check valve type and would become an opening to hemorrhage when hematocolposis worsened. Vaginoplasty and septum excision were performed in order to make a single vagina.
