Anorectal malformation (ARM) frequently involves urogenital anomalies, with higher incidence in severe ARM types. Early urinary tract evaluation is crucial even for low-type ARM to prevent renal dysfunction.

Area of Science:

  • Pediatric Surgery
  • Urology
  • Developmental Biology

Context:

  • Anorectal malformation (ARM) is a congenital condition often presenting with associated urogenital anomalies.
  • These anomalies can range from simple malformations to complex recto-urinary fistulas and neurogenic bladders.
  • The management of these co-occurring conditions requires a multidisciplinary approach.

Purpose:

  • To analyze the incidence and types of urogenital anomalies in patients with anorectal malformation (ARM).
  • To discuss the management strategies for associated urogenital anomalies in the neonatal and infantile periods.
  • To highlight the importance of early urinary tract evaluation in all ARM cases, irrespective of severity.

Summary:

  • A study of 57 ARM cases revealed a high incidence of urogenital anomalies (85.7% in high-type, 65.5% in intermediate-type, 38.1% in low-type ARM).

  • Vesicoureteral reflux (VUR) was the most common urinary tract anomaly (38.6%), followed by renal dysplasia, PUJ stenosis, megaureter, and urethral stenosis.
  • Five cases of renal dysfunction were observed, primarily due to VUR and renal aplasia, underscoring the need for comprehensive neonatal and infantile urinary tract assessment.

    • Impact:

    • Emphasizes the critical need for thorough urinary tract evaluation in all neonates and infants diagnosed with anorectal malformation, including low-type ARM.
    • Stresses the integral relationship between ARM management and the treatment of associated urogenital anomalies.
    • Promotes collaborative care between pediatric surgeons and urologists for optimal patient outcomes.
