Methods and materials
A retrospective analysis of our institution’s database for fetal urinary tract anomalies was made.
Ultrasound database of the Obstetrics and Radiology departments were reviewed and all prenatal diagnosis of urinary tract anomalies between January 2012 and July 2017 were included.
Follow-up data was obtained from the clinical records of Pediatrics and Pediatric Surgery departments.
Newborns with either prenatal or postnatal ultrasound performed at other institution and patients without proper follow-up data were excluded.
The diagnosis of ANH was based on the measurement of the anterior-posterior pelvic diameter (APPD) > 5mm in the 2nd trimester and > 7mm in the 3rd trimester.
A severe hydronephrosis was considered when the APPD of the pelvis was >10 mm in either the 2nd or 3rd trimester ultrasound.
Prenatal US examinations were compared with postnatal US diagnoses and surgical reports when newborns were submitted to surgery.
Data processing was made using SPSS version 20.0.
Statistical analysis was performed using linear regression and p-values <0.05 were considered statistically significant.
