Abstract
Introduction and Background: The Cook Resonance® metallic ureteral stent's unique configuration allows adequate urine drainage while providing improved resistance to external ureteral compression. We report a case in which a stent broke and subsequently uncoiled during stent removal under cystoscopy. Case Presentation: A 46-year-old woman with a history of cervical carcinoma treated with radiation therapy and chemotherapy and bilateral ureteral strictures presented for cystoscopic removal of bilateral Cook Resonance ureteral stents. During removal of the right ureteral stent, a snap was felt with subsequent uncoiling of the stent. Firm tension to the inner wire and outside curls allowed eventual complete removal of the stent without any retained fragments. Discussion: The all-metal Cook Resonance stent is an attractive alternative to polymeric stents because of reduced frequency of stent exchange and resistance to external compression. However, the metal stent possesses risks such as increased urothelial hyperplasia and stent embedment.
