title: Ureteroileal anastomotic strictures: an innovative approach with metallic stents.
abstract: OBJECTIVE
  We report our experience with the use of self-expandable metallic stents to bypass anastomotic strictures after ureteroileal urinary diversion.
  
  
  METHODS
  We evaluated 3 men and 1 woman with invasive bladder carcinoma who underwent radical cystectomy and ileal conduit urinary diversion. Ureteroenteric anastomotic strictures developed after a mean of 16 months. Self-expandable metallic stents were successfully placed (bilaterally in 2) comprising 6 stented ureters that bypassed strictures. Mean patient age was 64 years and mean followup was 12 months.
  
  
  RESULTS
  No restenosis was observed in 3 patients during followup. The stricture recurred 1 month after stent placement in the remaining patient and additional intervention was necessary, consisting of placement of a totally coaxial overlapping metal stent. No sepsis or other complication was observed. One patient died of metastatic disease 12 months after stent placement.
  
  
  CONCLUSIONS
  We propose the use of metal stents as an adequate, safe and effective alternative treatment for anastomotic strictures after ureteroileal diversion.
