Transrenal Ureter Embolization for Refractory Urine Leaks from Iatrogenic Ureteric Injury Following Colorectal Surgery.

We present the cases of two patients who underwent ureteral occlusion using coils and/or Amplatzer Vascular Plug with N-butyl cyanoacrylate glue after extensive advanced rectal surgery. Both patients had complex urine leaks unresponsive to urinary diversion. In view of the progress of the disease and the history of polysurgery, reconstructive surgery or anterograde ureteral stent insertion was not chosen. All patients had immediate resolution of urinary leakage after ureteral embolization, resulting in symptom relief throughout the follow-up period. There were no procedure-related complications or side effects.
