Normal constrictions of ureter are at all of the following sites EXCEPT:
Crossing iliac aery REF: Keith L. Moore, 4th edition, Page 117The ureters run inferomedially along the transverse processes of the lumbar veebrae and cross the external iliac aery just beyond the bifurcation of the common iliac aery. They then run along the lateral wall of the pelvis to enter the urinary bladder. The ureter lies on the anterior surface of the psoas major.The ureters are normally constricted to a variable degree in three places; these constricted areas are potential sites of obstruction by ureteric (kidney) stones:At the junction of the ureters and renal pelvis (Pelvi ureteric junction)Where the ureters cross the brim of the pelvic inletDuring their passage through the wall of the urinary bladder (Narrowest pa)
