Intraperitoneal laparoscopic single-site lymph node dissection in modified supine position during laparoscopic...

Area of Science:

• Urology
• Surgical Oncology
• Minimally Invasive Surgery

Background:

• Improving surgical ergonomics for upper tract urothelial carcinoma (UTUC) without patient repositioning is a persistent challenge.
• Current techniques may require complex patient maneuvering, increasing operative time and potential complications.

Purpose of the Study:

• To introduce and evaluate a novel technique for intraperitoneal laparoscopic single-site radical nephroureterectomy and lymph node dissection in a supine position.
• To assess the feasibility and efficiency of this technique for UTUC management.

Main Methods:

• Development and application of a novel intraperitoneal laparoscopic single-site approach.
• Simultaneous radical nephroureterectomy and pelvic/retroperitoneal lymph node dissection.
• Procedure performed entirely with patients in the supine position.

Main Results:

• The novel technique was demonstrated to be feasible.
• Significant improvements in operative efficiency were observed.
• The technique showed particular benefit in patients with locally advanced UTUC.

Conclusions:

• This novel supine, single-site laparoscopic technique is a viable option for radical nephroureterectomy and lymph node dissection in UTUC.
• The approach enhances operative efficiency, especially for complex cases.
• Further research can explore long-term outcomes and broader applicability.
