Purpose:
To report the outcomes of patients with ureteroenteric strictures after ileal conduit urinary diversion that were managed with Resonance metallic ureteral stents.
Patients And Methods:
Ten ureteroenteric strictures in patients with ileal conduits that were managed with metallic ureteral stenting were retrospectively identified. Charts were examined for patient age, anastomosis type, stricture cause, stricture laterality, complications, and follow-up.
Results:
Nine of 10 (90%) cases resulted in distal stent migration. Mean time to stent migration was 21 days (range 3-60 d).
Conclusions:
Placement of Resonance metallic stents in patients with ileal conduits is ineffective for management of ureteroenteric strictures because of the high rate of distal migration.

Esophageal Strictures-I: Introduction
Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...
