Ureters that show both reflux and obstruction.

R H Whitaker, C D Flower

    British Journal of Urology
    |December 1, 1979
    PubMed
    Summary

    This study reveals that ureters can experience both reflux and obstruction simultaneously. Severe obstruction may lead to minimal reflux, necessitating surgical reimplantation rather than conservative management.

    Area of Science:

    • Urology
    • Radiology
    • Pediatric Surgery

    Background:

    • Vesicoureteral reflux (VUR) and ureteral obstruction are common urological conditions.
    • The simultaneous occurrence of VUR and obstruction in the same ureter is considered unusual.
    • Understanding this dual pathology is crucial for effective patient management.

    Purpose of the Study:

    • To investigate the radiographic and dynamic characteristics of ureters exhibiting both reflux and obstruction.
    • To determine the relationship between the degree of obstruction and the severity of reflux.
    • To highlight the clinical significance of this combined ureteral pathology.

    Main Methods:

    • Radiographic imaging of the urinary tract.
    • Dynamic functional studies of ureteral and bladder function.
    • Analysis of eight ureters in six male patients with concurrent reflux and obstruction.

    Main Results:

    • A positive correlation was observed between the degree of ureteral obstruction and upper urinary tract dilation.
    • Severe obstruction can paradoxically present with minimal or absent reflux.
    • The degree of reflux may not accurately reflect the severity of obstruction in these cases.

    Conclusions:

    • The association of ureteral reflux and obstruction is an important clinical entity that urologists and radiologists must recognize.
    • Conservative management is generally inappropriate for patients with combined ureteral reflux and obstruction.
    • Surgical reimplantation of the ureters is the recommended treatment approach for this condition.
