Aim: The aim of our study is to value the efficacy of self-expanding Allium ureteral stent in the treatment of ureteral stenosis.
Methods: From 2010 to 2013, we treated 12 patients, aged from 23 to 64 years. Six patients were affected by congenital UPJ obstruction, four patients by iatrogenic unilateral ureteral stenosis and two patients by bilateral ureteral stenosis. All the patients showed hydronephrosis before the stenotic lesion and pain. In all the patients, we use a 30 Fr, 10 cm length self-expanding Allium ureteral stent. The medium follow-up is 10 months after Allium stent removal.
Results: All the patients were immediately free of pain after the procedure. We didn’t experience intra, peri and postoperative complications. In all the patients, a complete correction of the stenotic lesion was obtained. No recurrence of stenosis occurred during follow-up.
Conclusion: Self-expanding allium ureteral stent represents an effective treatment of ureteral stenosis in patients not suitable for surgery.
