Figure 1. (A) Nephrostogram immediately before nephrostomy tube placement shows severe hydroureter to the level of the pubic ramus (arrow), proximal to the site of ureteral incarceration. (B) Nephrostogram performed after the nephrostomy tube placement 2 months prior shows the urinary tract to be patent, but barely. The arrow demonstrates the site of ureteral incarceration in the inguinal hernia. Tube nephrostogram showed good internal drainage of the transplant kidney, and extravasation of contrast into the bladder is demonstrated.
