Robotic Off-Clamp Simple Enucleation Single-Layer Renorrhaphy Partial Nephrectomy (ROSS): Surgical Insights after an Initial Experience

Robotic technology allows the beginner surgeon to approach minimally-invasive partial nephrectomy (PN) avoiding the otherwise long learning curve of pure laparoscopy. The present video-article reported the surgical technique and the outcomes of the first 11 cases performed by a young surgeon starting with the experience of robotic PN. Transperitoneal robotic PN, with an off-clamp approach, a simple enucleation technique, and a single-layer medullar renorrhaphy was performed uneventfully in all cases but one, with comparable outcomes to the available literature. With the present experience, we are trying to give the reader a different point of view of the current knowledge. In our series, off-clamp robotic PN was not chosen while looking for a better functional outcome, but rather as a "forced" choice within the specific "in training" setting the interventions were performed in. We underline how the off-clamp approach was the way to cut out the potential for vascular complications derived from the application/removal of the clamp itself on the renal artery. Indeed, when Scanlan bulldogs are not available, one of the limits of robotic PN is that the first surgeon is not autonomous in placing/removing the clamp. We found that tumour enucleation resection technique had the perfect synergistic effect in maximizing the perioperative vision, and thus the safety, notwithstanding the clampless approach.
