Inverted Y ureteral duplication with an ectopic ureter and multiple urinary calculi: A case report

Figure 1 Abdominal computed tomography scans. A: One stone in the right upper ureter; B: Multiple stones in the right lower ureter; C: Other stones in the right kidney.

Figure 2 Computed tomography urography and three-dimensional reconstructions. A: Computed tomography urography; B: Three-dimensional reconstructions. The middle of the right ureter was divided into two branches, suggesting duplicated ureteral malformation with an ectopic ureter.

Figure 3  Intraoperative retrograde ureterography showed that the ectopic ureter was visible.

Figure 4  Duplicated ureteral bifurcation could be seen by endoscopy.

Figure 5  KUB after the operation showed that stones in the right upper ureter and renal pelvis had disappeared, a double J tube was placed, and multiple stones in the ectopic ureter were visible.
