Aim: The hymenal tissue is a membrane formed through the fusion of the paramesonephric ducts and the urogenital sinus which is perforated normally in utero period. If not perforated, imperforate hymen develops which is usually not diagnosed until pubertal age. The authors present a girl who underwent second operation for imperforate hymen. They aimed to increase the awareness about the possibility for recurrence after operation in these cases. Case: A 17-year-old girl was consulted with prolonged bleeding and chronic pelvic pain who had underwent hymenotomy four years ago because of imperforate hymen. On gynecologic examination, any opening that allows menstrual blood flow was not observed. There was no appearance of hematocolpos or hematometra on ultrasonography. The opening on the hymenal membrane was not seen but found with a Hegar dilator under general anesthesia in the operation room. The genital tract outflow was provided to admit one-gloved finger. Discussion: Imperforate hymen is the most common congenital cause of genital tract obstruction with an incidence of one in 1,000 to 2,000 girls. The most frequently preferred approach to establish the menstrual outflow is hymenotomy. These patients should be informed that there is a potential for adhesion, reclosure, and need for additional operations.
