Abstract:
A 70-year-old female suffered from gross hematuria and bladder tamponade. She had a solitary non-papillary tumor at the dome of the urinary bladder, underwent transurethral resection of the bladder tumor, and was diagnosed with an inflammatory myofibroblastic tumor positive for anaplastic lymphoma kinase proteins in immunohistochemistry. Subsequently, she underwent laparoscopic partial cystectomy using the Signia Stapling System due to the low-grade malignancy of the tumor. The patient has been under outpatient observation with no recurrence for 12 months post-surgery.
