Correlation of anorectal malformation complexity and associated urologic abnormalities

Area of Science:

• Pediatric Surgery
• Urology
• Developmental Biology

Background:

• Anorectal malformations (ARM) frequently present with associated urologic anomalies.
• Limited large-scale studies have characterized the incidence and associations between ARM severity and urologic diagnoses.
• This study aims to define urologic diagnosis rates in a large pediatric ARM cohort and explore correlations with malformation severity.

Purpose of the Study:

• To determine the incidence of urologic diagnoses in children with ARM.
• To evaluate the correlation between ARM severity and the number/incidence of associated urologic diagnoses.

Main Methods:

• Retrospective review of 712 pediatric patients with ARM.
• Protocolized urologic screening for all patients.
• ARM subtypes classified by severity in males and females; urologic diagnoses assessed for correlation with ARM severity.

Main Results:

• Overall urologic anomaly rate was 65% in males and 56% in females.
• Urologic anomaly rates significantly increased with ARM severity in both sexes (p<0.0001).
• Hydronephrosis and vesicoureteral reflux (VUR) incidence correlated significantly with increasing ARM complexity.

Conclusions:

• Urologic anomalies are highly prevalent in children with ARM.
• The frequency of urologic anomalies increases with ARM complexity.
• Emphasizes the need for early urologic screening and collaborative care in managing pediatric ARM patients.
