Abstract
- Exraadrenal paragangliomas are rare tumors of a neural crest origin. Their preoperative diagnosis can be suspected from the clinical history and biochemical examination of the catecholamines or their metabolic by-products. Surgery is the mainstay of therapy, but surgical removal makes an additional problem for the repair of the ureteral defect if a paraganglioma is located near the ureter or if it encloses the ureter. The ureteral repair often poses a therapeutic dilemma, and especially when the ureteral defect is too extensive to be repaired with traditional methods. We report here on a case of successful replacement with using appendix for the repair of a long ureteral defect that was caused by a retroperitoneal paraganglioma.
