title: Long ureteric stricture replacement by buccal mucosa graft: an Armenian experience case series report.
abstract: BACKGROUND
  The aim of this study is to demonstrate the results of a case series concerning the replacement of long ureteric strictures using buccal mucosa grafts.
  
  
  METHODS
  Five patients (3 men, 2 women), with a mean age of 35 years old, underwent reconstructive ureteral surgery using buccal mucosa graft with omental wrapping during the period of 2010-2013. In all cases, the location of strictures was in the proximal ureters with the length of strictures varying from 2.5 to 5.0 cm.
  
  
  RESULTS
  We did not observe any major complications postoperatively. Two patients complained of constipation, which was resolved on the second day without any special treatment. Only one patient experienced fever (39°C) on the seventh day after the surgery due to inadequate drainage of the nephrostomic tube. Mean follow-up time was 39.6 months (range 26-52 months), mean hospital stay length was 10.6 days. Intravenous and antegrade urography were performed after removing JJ stents. Results were favorable without any signs of stricture. Repetitive ultrasound and radiologic imaging was performed at month 3, 6, 12 in the first year and every half-year thereafter. Intravenous urography showed no signs of strictures. Hydronephrosis was resolved in all patients by the sixth month following the surgery.
  
  
  CONCLUSIONS
  Postoperatively, we observed favorable results in all patients in terms of absence of short term-surgical complications. This technique could be considered for patients with long ureteric strictures in whom ureteral replacement with bowel interposition or kidney auto-transplantation is contraindicated.
