Contrast was not visualized distal to the ureteropelvic junction (Figure 1). At 3-months follow-up, the patient was completely pain free, and an intravenous pyelogram revealed significantly decreased hydronephrosis and no evidence of UPJ obstruction (Figure 1).

An enlarged right ovarian vein, approximately 2.0 cm in diameter, was identified externally compressing the anterolateral aspect of the ureter near the ureteropelvic junction (Figure 2). The ovarian vein was carefully dissected from the ureter and divided with a vascular stapler (Figure 2). Thereafter, the UPJ appeared free of intrinsic obstruction (Figure 2).
