PURPOSE: Metal ureteral stents are a relatively new version of a device with a long history of relieving @entity1695 . Metal stents are effective for relieving @entity1695 but success regarding @entity1 tolerability has been variable. We present our single institution experience with long-term metal ureteral stent placement. MATERIALS AND METHODS: The charts of @entity1 undergoing metal ureteral stent placement for chronic @entity1695 were reviewed. Data collected included @entity1 age, gender, diagnosis/cause of obstruction, laterality, duration of indwelling metal stent, number of routine metal stent changes, complications and early discontinuations or stent changes. RESULTS: A total of 23 @entity1 underwent placement of metal ureteral stents between February 2008 and September 2010. Bilateral stents were placed in 5 @entity1 and 9 underwent a yearly metal stent exchange for a total of 42 ureteral units treated with metal ureteral stents. All metal stents were placed to relieve @entity1695 due to @entity1901 , @entity4145 , @entity3807 or extrinsic @entity5 . There were 3 metal stent failures in 2 @entity1 with malignant @entity1695 . There were no complications, or early discontinuations or changes due to adverse symptoms, @entity1 dissatisfaction, worsening renal function or progressive @entity3041 . CONCLUSIONS: Metal ureteral stents are effective for benign and malignant @entity1695 in the absence of @entity1791 . Good tolerability and annual stent exchange make metal stents an appealing alternative for @entity1 with chronic @entity1695 treated with indwelling ureteral stents.
