    — Ureter draining lower pole inserts in orthotopic (normal) trigonal position + is prone to reflux
    — Ureter draining upper pole inserts ectopically (abnormaly) medial + inferior to lower pole moiety ureter and frequently ends in ureterocele which can cause obstruction + may insert into vagina or rectum
  • VCUG: filling defect in bladder during early filling phase
