  1. Still not clear on the second step in the algorithm for none severe findings. Do we do a renal US on all babies w/ mild/moderate hydropnephrosis between 48hour-30days of age? and then based on APD continue on with algorithm?

  2. Yes – all babies with antenatally detected hydronephrosis should have a post-natal renal ultrasound. The difference is in the timing of the ultrasound: if concerning features present (e.g. bilateral/severe/features of PUV) then renal ultrasound should be done ASAP (ie. before baby goes home from hospital); if no high-risk features are present, it can be done as an outpatient in the first month of life.

  3. Thank you this is great. I will circulate to my obstetrical colleagues as we often the ones providing patients information about this when seen on their OB scans.


  4. Nice have the measurements as sometimes the radiologist summary can be misleading. Only do postnatal U/S if criteria met.for measurements in 2nd and 3rd trimesters.

  5. Thanks for providing algorithm. It will be nice if all Radiologists will report measurements instead of reporting mild or moderate.

  6. hi, what is the indication to do blood tests for kidney function?
