title: [Case of multiple encrusted stones on the ureteral stent left for 7 years: the efficacy of extracting the ureteral stent on transurethral lithotripsy].
abstract: A 48 years-old man had undergone transurethral lithotripsy (TUL) and Extracorporeal Shockwave Lithotripsy (ESWL) for bilateral ureteral stones and bilateral ureteral stents had been placed in 2001. He was lost to the follow-up for about 7 years after the removal of left ureteral stent. He had complained of right back pain and fever for two months. KUB showed right ureteral stones and encrustation along the ureteral stent. We performed TUL extracting the ureteral stent by silk, referring to silk loop technique. All stones and the encrusted ureteral stent were removed. This was very effective for patients with encrusted ureteral stent.
