Newborn Imperforate Hymen Resulting in Hydronephrosis

A girl was born at 39  weeks of gestation with a birthweight of 3325 g and an Apgar score of 9 and 10 at 1 and 5 minutes, respectively. Examination revealed a bulge of the introitus (Figure, A) characteristic of imperforate hymen. She was able to urinate spontaneously. A magnetic resonance imaging demonstrated hydr ometrocolpus (Figure, B, open arrow) with a 7.5-cm uterus. The enlarged uterus caused pressure on the left ureter, resulting in left hydronephrosis (Figure, B, solid arrow). An hymenectomy was performed with expression of approximately 25 mL of mucous and cultures of this fluid were negative.
