Percutaneous application of fibrin sealant in surgically recalcitrant urinomas following oncocytoma resection.

Surgical application of fibrin sealant is well established as a hemostatic agent. However, reports of its percutaneous application and its uses within the urinary tract are limited. Presented below are two patients with recalcitrant urinornas despite diversion therapy following partial nephrectomy for oncocytornas. Both patients were successfully treated with percutaneous application of fibrin sealant via a sheath at the time of percutaneous perinephric drain removal. Follow-up imaging demonstrated resolution of the urinornas with stabilization of creatinine. Percutaneous pplication of fibrin sealant may be considered as an alternative treatment for recalcitrant urinomas prior to surgical intervention, though more studies are required to confirm its effectivenes and safety.
