Case of the Week: Duplicated Collecting System (VCUG & Ultrasound)


Listen Later

In this radiology lecture, we discuss the imaging appearance of duplicated collecting system and ureterocele, with attention to US and VCUG.

Key points include:

  • Weigert-Meyer rule: Remember the mnemonic “DUMI.”
  • With duplex kidneys and complete ureteral Duplication, ureter draining Upper pole inserts ectopically into bladder Medially and Inferiorly to ureter draining lower pole.
  • Lower pole moiety inserts orthotopically.
  • Upper pole moiety often ends as an ectopic ureterocele.
  • Upper pole moiety tends to obstruct, and lower pole moiety is prone to reflux.
  • Obstructed upper pole moiety causes mass effect with resultant inferior displacement of the lower pole moiety and the “drooping lily” sign.
