Summary

Single-system ectopic ureters (SSEUs) in children often present with delayed diagnosis due to association with poorly functioning kidneys. Early endoscopic evaluation is crucial for timely diagnosis and management of SSEUs.

Area of Science:

  • Pediatric Urology
  • Congenital Abnormalities
  • Genitourinary Tract Malformations

Background:

  • Ectopic ureters in children typically drain duplex kidneys and present with symptoms related to abnormal ureteric orifice location or structure.
  • Single-system ectopic ureters (SSEUs) are a less common variant, often associated with a dysplastic or poorly functioning single kidney, potentially leading to misdiagnosis as a solitary kidney.

Purpose of the Study:

  • To analyze the diagnostic challenges and management outcomes of single-system ectopic ureters (SSEUs) in children.
  • To highlight the importance of maintaining a high index of suspicion for SSEUs in children with urinary symptoms and apparent solitary kidneys.

Main Methods:

  • Retrospective review of 11 cases of SSEUs managed over a 15-year period (1980-1995).
  • Analysis of clinical presentation, diagnostic methods, associated malformations, and surgical outcomes.

  • Comparison with the general population of ectopic ureters.

    • Main Results:

    • SSEUs were identified in 10 children, representing a distinct subset of ectopic ureters.
    • Diagnosis was often delayed due to association with small, dysplastic, or non-visualized kidneys, mimicking a solitary kidney.
    • Associated systemic malformations were common in SSEU cases.
    • Early endoscopic examination was key to diagnosis in most cases.

    Conclusions:

    • SSEUs represent a unique clinical entity within ectopic ureters, frequently associated with systemic malformations and diagnostic delays.
    • A high degree of suspicion is warranted for SSEUs in children presenting with wetting or recurrent infections alongside a presumed solitary kidney.
    • Prompt endoscopic evaluation is essential for accurate diagnosis and management of SSEUs, with generally gratifying surgical outcomes.
