Results In 29 cases of congenital ureter cyst, 14 occurred in right lateral, 12 in left lateral, and 3 in bilateral, totally being 32 cysts. The largest size of the cyst in diameter was (5.2) cm, and the smallest was (0.4) cm. Twenty-eight cases was diagnosed correctly by ultrasonography,in which the accuracy was (96.6)%(28/29). According to the sonographic patterns of size, shape, periodical change,1 case hydronephrosis, surgical and pathological results, 32 adult ureter cysts were divided into four types type Ⅰ, papillary(12); type Ⅱ, round or ellipse(9);type Ⅲ, semilunar(4);and type Ⅳ, oblate(7).
