Summary

Laparoendoscopic single-site (LESS) radical nephrectomy is a feasible and safe alternative to conventional laparoscopic surgery for kidney tumors. This minimally invasive approach demonstrated comparable operative times, blood loss, and recovery periods.

Background:

Conventional laparoscopic radical nephrectomy is a standard treatment for renal tumors.
There is a growing interest in further minimizing surgical invasiveness.
Laparoendoscopic single-site (LESS) surgery aims to reduce scarring and potentially improve cosmesis.

Purpose of the Study:

To evaluate the feasibility and safety of laparoendoscopic single-site (LESS) radical nephrectomy.
To compare the operative outcomes of LESS radical nephrectomy with conventional laparoscopic radical nephrectomy.

Main Methods:

Ten patients underwent LESS radical nephrectomy using single-port devices through a 4-cm incision.
Conventional laparoscopic radical nephrectomy was performed in 12 control patients.

Operative results were compared using statistical analysis (Mann-Whitney U test, Fisher exact test).

Main Results:

LESS radical nephrectomy was completed successfully in all patients without conversion.
No significant differences were observed in operative time, estimated blood loss, complication rates, or recovery metrics between LESS and conventional laparoscopic groups.
Mean operative times were 127.7 min (LESS) vs. 126.1 min (conventional), with comparable blood loss and hospital stays.

Conclusions:

LESS radical nephrectomy is technically feasible and offers comparable outcomes to conventional laparoscopy.
Further research, including long-term follow-up, is necessary to assess oncological control and optimize the technique for enhanced minimal invasiveness.
