Aggressive treatment for urothelial cancer-complete urinary tract extirpation: Operative feasibility in two cases.

Bladder cancer (BC), the most common malignancy of the urinary tract, accounts for 90-95% of all urothelial carcinomas (UCs), while upper urinary tract UC (UUTUC) accounts for only 5-10%. Radical nephroureterectomy with excision of bladder cuff, and radical cystectomy with pelvic lymph node dissection and a urinary diversion (UD) are the gold standard treatments for UUTUC and muscle-invasive bladder cancer (MIBC), respectively. These two treatments can be performed simultaneously when a bilateral or unilateral UUTUC is present with a MIBC, and are called complete urinary tract extirpation (CUTE) and hemi-CUTE, respectively. This complex surgery can help the patient by avoiding multi-staged surgeries, repeated anesthesia, and delay in completion of treatment. Herein, we report the first cases of a hemi-CUTE and CUTE in our department and share our experience with this aggressive and complex surgical treatment.
