The position of the largest cysts were at any site of the kidney. The number of these cysts were usually less than 10 in total renal section or were usually less than 5 in partial renal sectiurl. It was very difficult tu detect a rim of parenchyma in cases of advanced hydronephrosis especially in non-fun¬ctionin~ renal unite. Pulycystic kidney diseases represented 25 cases.The sonoqraphic pattern of polycystic kidney disease were the prnnnnrn of mult.iple cysts that. varied in size and shape and • The faces between them. The number of these cysts were enumerable.
