TF - Renal Agenesis and UPJ Obstruction

calyceal dilatation more important than pelviectasis
- When assessing the importance of urinary tract dilation, caliectasis is a much better indicator of a problem than pelviectasis which is seen commonly
Lying down adrenal sign
The absence of a kidney can sometimes be tricky to assess, particularly if there is low amniotic fluid. It is easier to search for a positive finding rather than the absence of a finding. Thus, to diagnose renal agenesis (absence of the kidney) finding an adrenal gland that lays next to the spine in a linear fashion rather than having the normal triangular shape is the best clue.
