Gelatin sponge (Spongostan?) and N-butyl-2-cyanoacrylate: Utility on percutaneous treatment of persistent urinary leakage after partial nephrectomy. Case report and review of the literature

摘要

Introduction: Percutaneous treatment of persistent urinary fistula after partial nephrectomy using N-butyl-2-cyanoacrylate and gelatin sponge (Spongostan?) is an effective and relatively non-invasive procedure that should be considered when a conservative approach fails. Three successful cases of percutaneous embolization by using N-butyl-2-cyanoacrylate have been reported in the literature. To our knowledge, the use of Spongostan for the treatment of urinary fistula after partial nephrectomy has not been previously described. Case report: We present the case of an 82-year old man who underwent percutaneous closure of a urinary fistula following partial nephrectomy by using gelatin sponge (Spongostan?) and N-butyl-2-cyanoacrylate.Conclusions: We encourage the use of this technique in selected cases. Collaboration amongst urologists and skilled interventional radiologist is strongly recommended.
