Association between severity of prenatally diagnosed hydronephrosis and receipt of surgical intervention postnatally among patients seen at a fetal-maternal center.

Background: Hydronephrosis (HN) is the most common abnormality detected on prenatal ultrasound. This study sought to stratify outcomes of patients by severity of prenatal HN with postnatal outcomes.

Methods: This was a retrospective review of patients referred to a tertiary care fetal-maternal clinic with diagnosis of prenatal HN from 2004 to 2019.

Mature Ovarian Cystic Teratoma Mimicking a Bladder Diverticulum in a 16-year-old Female.

A 16-year-old female was incidentally found to have an abnormal pelvic ultrasound while undergoing evaluation for mild scoliosis. A large, thick-walled, lobular, fluid-filled structure was found at midline in the pelvis that initially resembled bladder diverticula due to its anatomical position and sonographic appearance. Voiding cystourethrogram and computed tomography later revealed a large cystic mass originating from the right ovary.
