ABSTRACT
Malignant ureteral obstruction is a morbid diagnosis and can be difficult to manage. Ureteral stents often fail as the disease progresses. Metallic stents have provided a longer-term option for decompression as they inherently resist compression and require changes left often. However, changing metallic stents is challenging as it cannot be done over a wire as is done with plastic stents. We present a novel technique for safe and efficient exchange of the Resonance(®) metallic stent. We also review the literature on metallic stents.

Endoscopic injection treatment of vesicoureteral reflux is an increasingly common and successful option. Obstruction is an infrequent postoperative complication, occurring in 1% of patients; delayed onset of obstruction is even rarer. There is a paucity of literature describing possible treatments. We present a novel approach by excision of the implanted material.
