I have a baby girl who was born on 12th of March, 2014. The child was diagnosed with Hydronephrosis of the left kidney (which we were of before she was born) with following findings based on the Ultrasound that was done immediately after she was born. The left kidney is enlarged measures 5.8x2.6cm showing marked hydronephrotic changes. Residual parenchymal thickness 2.5mm. No definitely dilated ureter could be seen. The AP dimension of the renal pelvis measured at the hilum is 32mm. The right Kidney appears normal measures 4x2.1cm, average parenchymal thickness 9mm. The AP dimension of the renal pelvis at the hilum measures 5mm. No renal stones detected on either side. The liver is within normal range of size showing uniforn texture. No focal lesion noted. No intrahepatic biliary dilatation. Gall bladder appears normal The spleen is of normal size showing homogenous texture with no focal lesion. Mid line structures are marked by gases. Slight filling of the urinary bladder. No stones detected at he lower ureteric ends No ascites. Impression Advanced hydronephrotic changes of the left kidney, the possibility of PUJ obstruction is suggested. Further evaluation with contrast is suggested.
