Prenatal features of bladder agenesis in a female fetus with genital transposition

Bladder agenesis is a rare condition, mostly affecting females, where diagnosis is usually made in infancy when investigating urinary incontinence. Neonatal cases are uncommon, and none have been reported antenatally. The few male patients with this condition rarely survive: among associated anomalies, different degrees of penoscrotal transposition are the most evident feature. The association of genital transposition in a female infant with prenatal description of bladder agenesis has not been previously reported. Early diagnosis is important, enabling planning of surgical reconstruction early in life and appropriate parental counseling.
