Chronic Pelvi-Ureteric Junction Obstruction (PUJO)




1 yr old child on follow-up for prenatally detected renal pelvic dilatation.


Marked renal pelvic dilatation is noted with gross hydronephrosis. The renal pelvis appeared 'ballooned' and the dilatation appears to be disproportionate to the degree of calyceal dilatation. 




The AP diameter of renal pelvis measures 39mm (3.9cm). The dilated pelvi-calyceal system is showing internal echogenic particles. There is no past history of UTI.




High resolution USG with the linear 12MHz probe showed better the
marked thinning of renal parenchyma, measuring ~2mm only.




View of the ballooned markedly dilated renal pelvis with the linear probe.
