Comparing Surgical Outcomes of Off-Clamp and On-Clamp Robotic Partial Nephrectomy

What is it about?

The study compares the outcomes of off-clamp robot-assisted partial nephrectomy with preoperative superselective embolization and on-clamp robot-assisted partial nephrectomy with intraoperative ultrasound identification of the renal mass. The study found that preoperative superselective embolization significantly reduces operative time and intraoperative blood loss compared to on-clamp intraoperative ultrasound-guided robot-assisted partial nephrectomy. However, there was no significant difference in postoperative creatinine, hospital stay, and enucleated tumour volume between the two groups. Ten postoperative complications occurred in each group, with no significant difference in Clavien grade class, except for blood transfusions.

Why is it important?

This research is important because it compares the surgical and functional outcomes of off-clamp robot-assisted partial nephrectomy with indocyanine-green tumor marking through preliminary superselective embolization and on-clamp robot-assisted partial nephrectomy with intraoperative ultrasound identification of the renal mass. The study found that preoperative superselective embolization significantly reduces operative time and intraoperative blood loss compared to on-clamp intraoperative ultrasound-guided robot-assisted partial nephrectomy. This information can help urologists and surgeons make informed decisions about the best approach for their patients with renal masses. Key Takeaways: 1. Preoperative superselective embolization of a renal mass with indocyanine-green before off-clamp robot-assisted partial nephrectomy significantly reduces operative time and intraoperative blood loss compared to on-clamp intraoperative ultrasound-guided robot-assisted partial nephrectomy. 2. The study found no statistically significant differences in tumor size, R.E.N.A.L. score, postoperative creatinine, mean hospital stay, or enucleated tumor volume between the two groups. 3. Ten postoperative complications occurred in Group A (13.3%) and 11 in Group B (15.3%). Following superselective embolization, no patients required blood transfusions versus two patients in Group B.
