Brief Summary
Bladder cancer is the 4th most common cancer amongst men. If bladder cancer invades the muscle of the bladder or fails local treatments, surgical removal of the bladder (cystectomy) with creation of a new bladder from intestine is required. However, standard cystectomy affects urinary function and sexual function. The investigators are evaluating two modifications to cystectomy to determine to what extent they preserve urinary and sexual function.

Outcome Measures
Primary Outcomes (1)
Post-operative urinary function
Assess post-operative urinary function using the bladder cancer index (BCI) in patients randomized to either prostate capsule sparing cystectomy (PCSC) or nerve sparing radical cystoprostatectomy (NSC).

Study Arms (2)
Prostate capsule sparing cystectomy Group
ACTIVE COMPARATORProstate capsule sparing cystectomy involves removing the entire bladder.
Nerve sparing cystectomy Group
ACTIVE COMPARATORNerve sparing cystectomy involves removal of the whole bladder and the entire prostate.
Interventions
Removes the adenoma and prostatic urethra along with the urinary bladder, but leaves in situ the prostatic capsule and subsequently the surrounding neurovascular bundle.
Attempts to spare the cavernosal nerves that travel immediately adjacent to the lateral prostate and are routinely divided during a standard RCP.
Eligibility Criteria
You may qualify if:
- Study subjects will be men 18 years or older
- histologic diagnosis of Ta - T2 transitional cell carcinoma within 3 months of enrollment.
- no nodal or metastatic disease on pre-operative CT or MRI within 3 months of enrollment.
- no evidence of malignancy in the prostate based on 12-core transrectal ultrasound guided prostate needle biopsy and transurethral resection of prostatic urethra16
- candidate for and willingness to undergo a radical cystectomy and orthotopic neobladder by the urologic surgeon performing the procedure.
- competent to provide informed consent
- able to read and write English
- willing to be randomized to PCSC versus NSC.
You may not qualify if:
- histologically proven stage T3 or greater bladder cancer and/or evidence of metastatic disease by work-up described above.
- creatinine \> 2.2 mg/dl.
- refuse to complete study requirements.
- prior pelvic radiation to bladder or prostate.
- history of radical prostatectomy.
