*Anatomical terminology* [edit on Wikidata]

The orifices of the ureters are placed at the postero-lateral angles of the trigonum vesicae, 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 viscus these measurements may be increased to about 5 cm.
