    Functional
    Results of Pyeloplasty  in Patients with Ante-natally diagnosed Pelvi-Ureteric
    Junction Obstruction

    Br
    J Urol 81 : 152-155, 1998

     

    Method
    1984
    and 1995, 321 patients were referred with a
    diagnosis of antenatal hydronephrosis and were shown
    have PUJ obstruction. Pyeloplasty was performed if
    the relative renal function evaluated
    renographically before and at least 1 year after
    surgery.

     

    Results
      2
    patients had post operative urinary tract infection.
    From at total of 47 pyeloplasy . renographic
    reassessment showed no cases of continuing
    obstruction. Relative renal function was stabilized
    in patients who underwent early pyeloplasty.

      

    The
    mean differential function increased from 28.1%
    before surgery to 32.7% after surgery.

     

    Among
    patients who underwent pyeloplasty after a period of
    expectant management the mean relative function
    decreased from 44.8% initially to 30.5% before
    surgery. At postoperative reassessment there was a
    recovery of 37.5% indicating a statistically
    significant loss of function.

     

    Conclusion
    – Peloplasty failed to significantly improve
    function in patients born with PUJ obstruction and
    impaired renal function 
    perhaps because of cortical loss. Thus,
    although early pyeloplasty stabilizes function,
    expectant management must be vigilant to prevent a
    small but modest loss of renal function.

    The Role of Micturating Cystourethrography in Antenatally Detected Mild
    Hydronephrosis

    Pediatr
    Radiol 28: 152-155, 1998

        

    Conclusion
    -
    All  infants
    with mild hydronephrosis should undergo MCUG. This
    assessment need not be delayed until 3 months,
    rather, it would be performed after a 6 week US
    scan.
