10 Years of Antenatal Hydronephrosis Experience: Comparing Two Different Guidelines

Area of Science:

• Pediatric Nephrology
• Fetal Medicine
• Medical Guidelines

Background:

• Antenatal hydronephrosis (AH N) involves fetal renal pelvis dilation.
• Distinguishing transient AH N from cases needing intervention is challenging.
• Current guidelines aim to standardize AH N management.

Purpose of the Study:

• To compare the efficacy of the 2015 Turkish Society of Pediatric Nephrology guideline with a prior hospital guideline for AH N.
• To evaluate diagnostic yield, invasiveness, and radiation exposure.

Main Methods:

• Comparative analysis of two AH N management guidelines.
• Data collected included demographics, outcomes, imaging, radiation exposure, and surgical rates.
• Two groups were analyzed based on the guideline applied.

Main Results:

• The new guideline (Group 2) showed a higher detection rate of Vesicoureteral Reflux (38.5% vs 13.4%).
• Group 2 had a higher obstruction diagnosis rate (68.8% vs 29.4%) but lower radiation exposure (200 mrem vs 500 mrem).
• Fewer surgical interventions were noted with the new guideline (21.9% vs 34.2%).

Conclusions:

• The new guideline is less invasive and requires fewer diagnostic tests.
• It leads to reduced radiation exposure for patients with antenatal hydronephrosis.
• The updated guideline demonstrates improved diagnostic accuracy and management efficiency.
