The field of laparoendoscopic single-site (LESS) surgery has progressed significantly since the initial cases were attempted ≈ 5 years ago. Most ablative and reconstructive procedures that have been performed using either conventional laparoscopy or robot-assisted laparoscopy have been successfully performed using LESS techniques [1-4].
LESS partial nephrectomy (LESS-PN) remains a challenging procedure, and should only be attempted by that select cohort of surgeons who have had adequate experience with extirpative and other reconstructive LESS procedures, e.g. LESS pyeloplasty. It will be useful to see whether a comparative trial between robot-assisted PN, robotic LESS-PN and conventional LESS-PN will show any significant differences.
