kidney obstruction

  Our son born 8-24- 98 was diagnosed with mild hydronephrosis in utero.
  since then, reflux has been ruled out, but the lasix renogram showed
  moderate obstruction of the right and mild of the left kidney. the obstruction
  appeared at the kidney ureter junction. percentage was 38% right and 62% left.
  recommendations were moniter every three months with lasix renogram and operate
  if recurring infection or kidney damage becomes evident. I have read information from
  another ped urologist that early surgery was recommended that would return any lost
  kidney function and take the compensatory pressure off the left kidney. this
  seem contradictory. I would appreciate any suggestions. Also he incidentally was born with
  very mild hypospadia and chordee.
  thank you for you time and informaiton

Dear Mike
Thanks for your questions.
Bilateral hydronephrosis secondary to  bilateral UPJ obstruction is rare. The verdict is still out with regards to early/ late operation verse observation  for UPJ obstructions.  Dr. King et al ,in 1984,  recommend early surgery.  Dr. Ransley et al , 1990, recommend surgery if function in one of the renal units is less than 40% and Drs. Koff and Campbell, 1992 recommend  observation only..  Multiple genitourinary abnormalities are more common when at least one is present.
More individualized care is available at the Henry Ford Hospital and its urban campuses by calling  (1 800 653 6568). We can also arrange local accommodations through this number if this is your need. Please bring any physicians
