Figure 2a. Intravenous urogram in this patient who had previously undergone a right nephroureterectomy and left ureteral resection with ileal interposition suggests a 3 cm filling defect (arrow) in the left lower infundibulocalyx.

Figure 2b. Tomographic view confirms a 3 cm. irregular filling defect (arrow) consistent with recurrent TCC.

Figure 2c. Fluoroscopic view of percutaneous access in preparation for percutaneous electroresection of the tumor.

Figure 2d. Nephrostogram 48 hours after percutaneous resection reveals no residual tumor. There was no obstruction or extravasation, and a six weekly course of percutaneous BCG was begun 2 weeks later.
