An association of prune belly anomaly with trisomy 21

Abstract
We report on two patients wth prune belly anomaly (PBA) and trisomy 21 documented by clinical examination and cytogenetic investigation. The first infant was diagnosed at birth. A distended bladder was detected prenatally by ultrasound in the second, and chromosome studies were performed on cells obtained from fetal “bladdercentesis.” We discuss the importance of cytogenetic studies in cases where fetal surgery is a consideration.
