Segmental renal dysplasia occurs in 67% of patients with complete pyeloureteral duplication. Associated ureteric anomalies often drain these dysplastic segments, complicating diagnosis and treatment.

Area of Science:

  • Urology
  • Pediatric Nephrology
  • Pathology

Background:

  • Complete pyeloureteral duplication is a congenital anomaly.
  • Segmental renal dysplasia can be associated with urinary tract abnormalities.
  • Accurate diagnosis and management are crucial for preserving renal function.

Purpose of the Study:

  • To determine the frequency of segmental renal dysplasia in patients with complete pyeloureteral duplication.
  • To investigate the association between renal dysplasia and ureteric anomalies.
  • To discuss the clinical significance and diagnostic challenges of dysplastic renal segments.

Main Methods:

  • Retrospective analysis of 15 patients with complete pyeloureteral duplication.
  • Review of anatomopathologic diagnoses from partial nephrectomies and renal biopsies.

  • Correlation of renal dysplasia findings with coexisting ureteric anomalies.

    • Main Results:

    • Segmental renal dysplasia was identified in 10 out of 15 patients (67%).
    • The remaining 5 patients were diagnosed with chronic pyelonephritis.
    • All dysplastic segments were associated with ureteric anomalies, including ureteral ectopia, ectopic ureteroceles, and vesicoureteral reflux.

    Conclusions:

    • Segmental renal dysplasia is a frequent finding in complete pyeloureteral duplication.
    • Associated ureteric anomalies play a significant role in the presentation and management of these cases.
    • Diagnostic difficulties arise from poorly functioning dysplastic renal segments, necessitating careful clinical and pathological evaluation.
