Case ReportsInitial experience with full-length metal stent to relieve malignant ureteral obstruction.
Ureteral obstruction caused by extrinsic compression by a malignancy generally can be overcome initially with a ureteral stent. However, the long-term failure rate is high, usually necessitating placement of a nephrostomy tube. ⋯ The obstruction failed to respond to placement of a single 7F double-J stent and then of two 6F double-J stents in the left ureter. As a last resort, in order to avoid nephrostomy-tube placement, the 6F metal stent was placed; this provided unobstructed flow of urine, as documented on a subsequent Whitaker test and, most recently, on a renal scan, 4 months after initial stent placement.
