Embolization of Urinary Tract Fistulae Using an AMPLATZER Vascular Plug and Glue

Abstract

Six patients (mean age, 57.7 y ± 19.7) with persistent urinary fistulae underwent 7 urinary tract embolizations with AMPLATZER Vascular Plugs (AVPs) and glue: 5 with concomitant cavity obliteration with glue and 2 without. A single procedure was successful in resolving urinary leakage in 5 patients (71%) at a mean follow-up of 27.3 wk ± 31.5 (median, 9.7 wk; range, 4.9–80 wk). Repeat cavity embolization was required in 2 instances to achieve clinical success. Mean survival was 42.3 wk (median, 16.4 wk; range, 11.7–104 wk). Combined AVP and glue embolization may prove to be a primary approach in the control of persistent fistulae.
