Current evidence for robotic surgery in radical cystectomy

摘要

Robotic-assisted radical cystectomy (RARC) has been gaining momentum as an alternative to its conventional open radical cystectomy (ORC) for the management of invasive bladder cancer. Although RARC, in general, demonstrated less blood loss and shorter hospital stay than ORC, whether there is any significant difference in the overall complication rate still requires further investigation. Thus, both RARC and ORC share a similar oncology outcome, with comparable positive surgical margin rates, disease-free survival, and overall survival. Techniques of intracorporeal urinary diversion (ICUD) have not yet been standardized. ICUD may result in a lower risk of ureteroileal anastomotic stricture than extracorporeal urinary diversion (ECUD). However, ECUD is still a valid and commonly practiced option according to the available data. In general, RARC has been demonstrated to provide promising results. Long-term data and functional outcome after RARC and ICUD are needed to further validate the role of RARC in the management of bladder cancer.
