Duplicated collecting system

Case contributed by Dr Bruno Di Muzio


One year old boy with recurrent urinaty tract infections.

Patient Data

Age: 1
Gender: Male

CT Abdomen and pelvis

Modality: CT

Multiplanar CT study during the excretory phase shows (left side):

  • Complete duplicated ureters extending down to the bladder (the proximal extremity that begins at lower pole is partially characterized on this study).
  • No signs of ureteroceles on bladder. 
  • Vesico-ureteric reflux into the distal extremity of left ureters. No contrast into the pyelo-ureteral system of the lower renal pole was seen.
  • Lobulated renal contour with multiple internal cysts areas in lower renal pole that seens to be a pyelo-ureteral dilatation. This nonfunctioning lower pole mimics a renal mass.

Case Discussion

duplicated collecting system is one of the most common congenital renal tract abnormalities.
