RESUMEN
A 76-year-old woman presented with gross hematuria. She had received transurethral resections (TURBT) twice for superficial bladder tumors near the right orifice. All pathologic findings demonstrated low grade superficial transitional cell carcinoma (TCC). Cystoscopy showed the tumor lesions during the follow-up. Bladder tumors were completely harvested and pathologic examination revealed inverted papilloma. However, recurrent tumors were detected at the same location after 4 months' follow up. Although she came to our hospital for the purpose of TURBT, she complained of severe neck pain and was suddenly dead. Autopsy findings showed that dissecting aortic aneurism was the cause of death and the bladder tumor was low grade superficial TCC. The case reported here had a very rare pathologic finding with a history of superficial tumors located in the same areas in the urinary bladder.

Migration of surgical materials into the urinary tract is very rare. We present a case of spontaneous migration of a metal clip into renal pelvis after laparoscopic pyeloplasty. A 44-year-old woman who had a long history of multiple sclerosis presented with symptomatic left hydronephrosis due to ureteropelvic junction (UPJ) obstruction. Since antegrade endopyelotomy was unsuccessful, the patient underwent laparoscopic Anderson-Hynes pyeloplasty. The UPJ was wrapped with thick inflammatory tissue and a crossing vessel that firmly adhered to the UPJ was found and dissected. Metal clips were used for hemostasis. Although the hydronephrosis was improved and flank pain was completely dissolved, a stone was identified in the pelvis 22 months after the surgery. The stone was formed around a metal clip that had been possibly migrated into the renal pelvis. Transureteral lithotripsy was performed using an 8F ureterofiberscope and a clip was removed.
