Robot-assisted Partial Nephrectomy for Complex (PADUA Score ≥10) Tumors: Techniques and Results from a Multicenter Experience at Four High-volume Centers.

Background: Robot-assisted partial nephrectomy (RAPN) represents a widely accepted minimally invasive alternative to open and laparoscopic surgery for the treatment of clinically localized renal tumors.

Objective: To assess the feasibility of RAPN in a contemporary series of patients with highly complex tumors (PADUA score ≥10) treated at four high-volume robotic surgery institutions.

Design, Setting, And Participants: Data from a prospectively maintained multi-institutional database on patients subjected to RAPN between 2010 and 2017 were reviewed.

Tumor enucleoresection in robot-assisted partial nephrectomy.

The objective of this study is to describe our technique and results of the enucleoresection technique in robot-assisted partial nephrectomy. The patient is positioned in full flank position. Three robotic arms of a da Vinci system and an assistant's port are used.

Failure of a robotic arm during da Vinci prostatectomy: a case report.

We report a rare case of a da Vinci robotic arm failure during a laparoscopic robot-assisted radical prostatectomy. The articulation joint of an Endowrist needle driver was broken and positioned at such an angle that made it impossible to remove through the trocar. In addition, it was later discovered that a small piece of the instrument was detached and remained inside the abdomen of the patient without even having been identified on subsequent radiological evaluation.
