Ureteric constrictions are at all sites EXCEPT:: (A) Pelvi-ureteric junction, (B) Lesser pelvis, (C) Ischial spine, (D) Urinary bladder wall

Ureter has five constrictions in its course: Pelvi-ureteric junction (tip of transverse process of veebra, radiologically) Pelvic brim (sacro-iliac joint radiologically) At vas deferens At Ureterovesical junction (ischial spine, radiologically) Opening at trigone.
