Summary
This study presents a nerve-sparing robot-assisted radical cystoprostatectomy (RRCP) technique for bladder cancer. The novel approach enables precise tumor removal while preserving nerves, potentially improving patient outcomes.
Area of Science:
- Urology
- Surgical Oncology
- Robotic Surgery
Background:
- Bladder cancer necessitates radical cystoprostatectomy (RC) with urinary diversion.
- Preservation of neurovascular bundles during RC is crucial for maintaining erectile function.
- Minimally invasive techniques aim to improve surgical precision and reduce morbidity.
Purpose of the Study:
- To develop and describe a nerve-sparing robot-assisted radical cystoprostatectomy (RRCP) technique.
- To evaluate the feasibility and preliminary outcomes of this novel surgical approach.
Main Methods:
- A three-step technique for RRCP and urinary diversion using the da Vinci Surgical System was developed.
- Pelvic lymphadenectomy and cystoprostatectomy were performed robotically with neurovascular bundle dissection.
- Extracorporeal neobladder creation followed by robotic-assisted anastomosis was utilized.
Main Results:
- RRCP was successfully performed in 17 patients (14 men, 3 women).
- Mean operative times for cystectomy and neobladder creation were 140 and 168 minutes, respectively.
- Mean blood loss was less than 150 mL, with all resection margins free of tumor.
Conclusions:
- A nerve-sparing RRCP technique using the da Vinci system allows precise bladder removal with minimal blood loss.
- Extracorporeal neobladder creation through the specimen extraction incision reduces operative time.
- This technique facilitates complex urinary reconstructions while preserving critical nerves.
