Markedly dilated left renal pelvicalyceal system down to the PUJ where abrupt transition has been seen and hence no dilated caliber seen.
The left kidney shows relatively enlarged size (nephromegaly) with lobular contour and markedly reduced parenchyma (thinned out) as well as relatively attenuated left renal artery suggesting chronicity.
Poor/No contrast excretion of the left kidney suggesting a poor renal function.
Few tiny left renal calcifications/ gravels.
Other incidental findings; mild fatty liver, left small inguinal hernia, and colonic gaseous distension.
