En-bloc Transurethral Resection of Bladder Tumor (En-bloc TURBT) Specimens Using a Redesigned Surgical Resectoscope Device
Sponsor: National Cancer Institute (NCI)
Summary
Background: Bladder cancer is the sixth most common cancer in the United States. The way that doctors remove tumors in bladder surgeries may leave some cancer . Also, many people have their tumors return or progress after surgery. Researchers want to test a modified device. It might tell doctors more about bladder tumors. Objective: To see if using a modified standard device with bladder surgery can provide better information about tumors in bladder specimens. Eligibility: People ages 18 and older who need to have their bladder removed at the NIH. Design: Participants will be screened with: Medical and prior surgical history Review of existing MRI, x-ray, or CT scans Review of existing specimens and reports Pregnancy test for women of childbearing age CT or MRI: Participants will lie in a machine. The machine will take pictures of their body. Participants will have bladder surgery. This will occur in the same way as if they did not take part in this study. A member of the research team will cut the removed bladder using the modified device. This will most likely be done on a separate back table in the operating room. The bladder and samples after cutting will be sent out for review. The will occur just as it would if the participants were not in this study. The only difference is the way that the specimen is prepared for review. Participants follow-up care will occur per standard of care. Or it will occur as part of any other study in which they might also be enrolled.

Conditions
Interventions
modified resectoscope
The modified resectoscope will be used post cystectomy (En-bloc TURBT) to resect areas of the tumor from the cystectomy specimen. These resected tumors will be sent for histopathology to assess the size of resection, depth of resection, and ability to ascertain tumor orientation and compared to the remainder of the cystectomy specimens to see if the modified resectoscope can provide improved pathologic standards for the TURBT procedure.
TURBT
All patients will receive routine surgical transurethral resection of bladder tumors (TURBT).
