Objective: Our purpose was to determine the degree of fetal pyelectasis predictive of neonatal renal pathologic processes.
Study Design: Eighty-four cases of pyelectasis were identified during the study period (1989 through 1993). Fetuses with anteroposterior diameter of the renal pelvis > or = 4 mm before 33 weeks or > or = 7 mm after 33 weeks without caliectasis were included.
