The liver is normal in size and parenchymal echogenicity. No focal hepatic mass lesion is seen. The intrahepatic biliary channels and CBD are not dilated. 
The gallbladder is moderately distended with bile and clear contents and mucosal wall thickness. No calculus is seen within it. 
The kidneys are normal in their position, shape, outline and parenchymal echogenicity. The left kidney is however enlarged, measuring 125mm x 64mm in dimension, with associated moderate dilatation of its pelvicalyceal system and proximal ureter. No calculus is seen.
The spleen, pancreatic bed and paraaortic area are within normal limits.
The visualized bowel loops shows normal caliber, outline and peristaltic activity. No bowel mass lesion is seen. 
The urinary bladder and prostate gland are within normal limits.

Conclusion;- Right moderate hydroureteronephrosis presumably due to distal ureteric obstruction from Calculus.
NB: IVU is recommended for further evaluation
