Retroperitoneal laparoendoscopic single-site surgery in urology: initial experience

Area of Science:

• Minimally Invasive Surgery
• Urologic Surgery
• Laparoscopic Techniques

Background:

• Single-port laparoscopic surgery offers potential advantages in reducing surgical trauma.
• The retroperitoneal approach provides a distinct surgical plane for urologic procedures.

Purpose of the Study:

• To evaluate the initial experience with single-port laparoscopic urologic surgery.
• To assess the feasibility of the retroperitoneal approach using flexible instrumentation.

Main Methods:

• Retrospective review of 14 patients undergoing single-port laparoscopic urologic surgery.
• Procedures included renal cyst decortication, adrenalectomy, nephroureterectomy, nephrectomy, and ureterolithotomy.
• The Alexis wound retractor facilitated the single port for retroperitoneal access.

Main Results:

• All 14 cases were successfully completed without conversion to open or standard laparoscopic surgery.
• Mean operative times varied by procedure type, with renal cyst decortication averaging 56 minutes.
• Mean estimated blood loss and hospital stay (6.5 days) were recorded; two patients experienced wound dehiscence and bleeding.

Conclusions:

• Retroperitoneal single-port laparoscopic urologic surgery is technically feasible.
• This approach is particularly suitable for procedures requiring free-hand suturing.
• Initial clinical outcomes for organ-ablative, extirpative, and reconstructive surgeries are reported.
