AbstractImperforate hymen is the most common congenital malformation of the female genital tract. It can manifest in the neonatal period as hydrocolpos or at menarche as hematocolpos. The clinical manifestations of hydrocolpos include: bulging membrane at introitus, lower abdominal cystic swelling, abdominal distention, difficulty in emptying the bladder. The diagnosis of hydrocolpos is by USG and MRI. The anomalies associated with the hydrocolpos are imperforate anus, persistent urogenital sinus, cloacal dysgenesis etc. The surgical treatment can be simple hymenotomy or hymenectomy while laparotomy is indicated for the treatment of abdominal complications. Complications of hydrocolpos are hydronephrosis, chronic kidney
