Postnatal outcome of isolated antenatal hydronephrosis

Area of Science:

• Perinatal medicine
• Fetal imaging
• Pediatric urology

Background:

• Renal pelvis dilatation (RPD) is a common finding in fetal ultrasounds.
• Early detection of RPD is crucial for assessing postnatal outcomes and potential interventions.

Purpose of the Study:

• To evaluate the postnatal outcomes of fetuses diagnosed with renal pelvis dilatation (RPD).
• To determine the incidence and severity of RPD in a specific population.
• To assess the need for surgical intervention following antenatal diagnosis of RPD.

Main Methods:

• Retrospective analysis of 61 fetuses with RPD diagnosed via antenatal ultrasound (US) between January 2008 and January 2012.
• Exclusion of cases with intrauterine fetal death, early neonatal death, or loss to follow-up, resulting in 34 cases for analysis.
• Data collection on RPD degree, postnatal diagnosis, and surgical intervention requirements from patient files.

Main Results:

• The incidence of isolated RPD was 6.1% among 990 fetuses with sonographic abnormalities.
• Of the 34 analyzed cases, 44% had severe RPD, 41% moderate, and 15% mild.
• Only 21% of the fetuses (7 out of 34) required surgical intervention after birth.

Conclusions:

• Routine antenatal ultrasonography enables early diagnosis of fetal urologic conditions.
• Early detection of RPD facilitates timely management and improves postnatal outcomes.
• The majority of fetuses with RPD do not require surgical intervention, underscoring the importance of accurate postnatal assessment.
