<P> In humans , the ureters arise from the pelvis of each kidney , and descend on top of the psoas major muscle to reach the brim of the pelvis . Here , they cross in front of the common iliac arteries . They then pass down along the sides of the pelvis , and finally curve forwards and enter the bladder from its left and right sides at the back of the bladder . This is classically depicted as running `` posteroinferiorly on the lateral walls of the pelvis and then curve anteromedially to enter the bladder '' . The orifices of the ureters are placed at the postero - lateral angles of the trigone of the bladder , and are usually slit - like in form . In the contracted bladder they are about 2.5 cm. apart and about the same distance from the internal urethral orifice ; in the distended bladder these measurements may be increased to about 5 cm . </P>
