Late second trimester assessment of pyelectasis (SERP) to predict pediatric urological outcome is improved by checking additional features.

Objective: Counseling for pyelectasis in the late 2nd trimester is usually based only upon assessing the antero-posterior (AP) width of the renal pelvis. We hypothesized that checking additional features would better predict postnatal outcome.

Study Design: Ultrasound (<24 weeks gestational age (GA)) and newborn outcome data collected prospectively since 1986 were analyzed retrospectively.

Fetal bladder sagittal length: a simple monitor to assess normal and enlarged fetal bladder size, and forecast clinical outcome.

Purpose: We examined if the parameter of fetal bladder sagittal length (FBSL) could serve as a monitor of normative and enlarged fetal bladder size.

Materials And Methods: There were 76 consecutive cases examined between 1984 and 2000 that included measurement of fetal bladder size as FBSL and postnatal urological followup. Fetal images used to assess normal bladder size were derived from cases in which the bladder was normal on prenatal imaging and postnatal testing.
