Therapeutic ureteral occlusion with n-butyl cyanoacrylate glue and an AMPLATZER plug scaffold

摘要

Percutaneous nephrostomy, nephroureterostomy, and ure-teral stents are procedures commonly performed in patients who require urinary diversion. These procedures reduce outflow through the ureter but do not completely prevent the downstream flow of urine. Permanent occlusion of the distal urinary tract may be desired, such as in the setting of extensive pelvic malignancy associated with urinary leaks (1). A wide variety of techniques for percutaneous ureteral occlusion have previously been described. Previous large-scale studies found the use of silicone-filled balloons more effective than tissue adhesive with Gianturco coils (2,3).
