First Comparison of Retroperitoneal Versus Transperitoneal Robot-Assisted Nephroureterectomy with Bladder Cuff: A...

Area of Science:

• Urology
• Surgical Oncology
• Minimally Invasive Surgery

Background:

• Upper tract urothelial cancer (UTUC) management often involves nephroureterectomy.
• Robot-assisted transperitoneal nephroureterectomy (TRNU) is the current standard of care.
• Robot-assisted retroperitoneal nephroureterectomy (RRNU) presents a novel surgical approach.

Purpose of the Study:

• To compare the safety and efficacy of RRNU versus TRNU for UTUC.
• To evaluate perioperative outcomes and complication rates between the two surgical techniques.

Main Methods:

• Retrospective analysis of robot-assisted nephroureterectomies (NUs).
• Comparison of TRNU and RRNU groups based on patient demographics, tumor characteristics, and intra/postoperative complications.
• Statistical analysis to determine significant differences (p < 0.05).

Main Results:

• No significant difference in intraoperative or postoperative complications between RRNU and TRNU.
• RRNU demonstrated significantly shorter surgery time and length of hospital stay.
• RRNU resulted in the removal of a significantly higher number of lymph nodes.

Conclusions:

• RRNU is a safe and feasible alternative to TRNU for UTUC treatment.
• RRNU offers potential advantages in terms of operative efficiency and lymph node dissection.
• RRNU expands minimally invasive treatment options, especially for patients with prior abdominal surgery.
