Fig. 5E 40-year-old woman with von Hippel-Lindau disease and multiple
renal masses who underwent radiofrequency ablation and developed ureteral
injury and urine leak requiring urinoma drainage and stenting of ureter. Spot
fluoroscopic image with antegrade injection of contrast material shows leak of
contrast material at site of proximal ureteral injury (arrow). This
is not same site as upper pole calyceal leak shown in C, but spasm at
site of ureteral injury contributed to persistent calyceal leak. Lower
catheter was in place to drain urinoma.
