the ureter connects to the kidney at the urethra.
where does the ureter connect to the kidney?
urethra
the ureter has a diameter of but there are three constrictions, which are the most common sites of renal calculus obstruction:









































bullet::::1. at the pelvi-ureteric junction (puj) of the renal pelvis and the ureter









































bullet::::2. as the ureter enters the pelvis and crosses over the common iliac artery bifurcation









































bullet::::3. at the vesicoureteric junction (vuj) as the ureter obliquely enters the bladder wall









































section::::structure.:blood supply.









































the ureter has an arterial supply which varies along its course.









































bullet::::1. the upper part of the ureter closest to the kidney is supplied by the renal arteries
