Himen imperforado neonatal

Imperforate hymen is the most common obstructive anomaly of the female genital tract. Although this abnormality often goes unnoticed in neonates, it is relatively simple to diagnose. Diagnosis is based on history taking and thorough physical examination. Imaging studies can also be used, if required, and the procedure of choice is ultrasonography. Early diagnosis prevents the morbidity associated with late diagnosis. Consequently, thorough and systematic examination of the genital area is advisable and should form part of all pediatric examinations. When vaginal outflow obstruction is found, the urinary tract should be examined. The treatment of choice is hymenotomy. However, consensus is lacking on the optimal timing of this procedure.
