The left kidney is of duplex anatomy with a hydronephrotic upper moiety. The left ureter is dilated down to the distal end where an intravesical ureterocele can be seen, separate from the indwelling catheter. 

Note the posterior dislocation of the right hip with an associated acetabular fracture.

Case Discussion

This case depicts a characteristic duplex kidney, and its frequent association with ureterocele, which leads to a hydronephrotic upper moiety.
