Reflux induced pelvi-ureteric obstruction.

R H Whitaker

    British Journal of Urology
    |January 1, 1976

    Summary
    This summary is machine-generated.

    Pelvi-ureteric obstruction caused by vesico-ureteric reflux is often over-diagnosed based on imaging. Confirming true obstruction is crucial before pyeloplasty, as ureter reimplantation may resolve pelvic dilatation.

    Area of Science:

    • Pediatric Urology
    • Nephrology
    • Radiology

    Background:

    • Vesico-ureteric reflux can induce pelvi-ureteric obstruction.
    • Radiographic findings may lead to over-diagnosis of obstruction.
    • The exact mechanisms of this obstruction are not fully understood.

    Purpose of the Study:

    • To differentiate true pelvi-ureteric obstruction from apparent obstruction due to vesico-ureteric reflux.
    • To emphasize the importance of confirming obstructive uropathy before surgical intervention.
    • To explore the active nature of the obstruction.

    Main Methods:

    • Review of radiographic findings in cases of pelvi-ureteric obstruction secondary to vesico-ureteric reflux.
    • Correlation of imaging findings with clinical outcomes.

    Related Experiment Videos

  • Assessment of treatment response to ureter reimplantation versus pyeloplasty.

    • Main Results:

    • Radiographic evidence of obstruction can be misleading, suggesting over-diagnosis.
    • Ureter reimplantation effectively addresses pelvic dilatation when obstruction is not definitively confirmed.
    • The obstructive process appears to have an active component.

    Conclusions:

    • Accurate diagnosis of pelvi-ureteric obstruction secondary to vesico-ureteric reflux is critical.
    • Surgical intervention should be guided by confirmed obstructive findings.
    • Further investigation into the active mechanisms of obstruction is warranted.
