Robotic-assisted versus laparoscopic partial nephrectomy : an experience with a novel technique of suturing

Abstract EN

This study was conducted to evaluate whether robotic-assisted laparoscopic partial nephrectomy (RALPN) is superior to laparoscopic partial nephrectomy (LPN) with regard to warm ischemia time and complications and, in addition, to report our novel technique of suturing in partial nephrectomy (PN).

This was a prospective study carried out over a period of six years at our institute.

A single surgeon performed PNs laparoscopically (17) and with robotic assistance (16).

Only exophytic tumors were included and a novel technique of knotless and bolster-less suturing using Hem-o-loc clips was used to close the renal defect.

There was no difference in intra-operative and post-operative blood loss between the two groups.

However, LPN patients had significantly longer mean warm ischemia time (24.1 vs.

30.1 min, P <0.001) and operating time (157.5 vs.

192.5 min, P <0.001).

Also, hospital stay was comparable between the two groups.

RALPN is technically easier and also safer than LPN because of its advanced degrees of freedom, decreased warm ischemia time and reduction in the total operating time.

However, these observations need further validation by larger and randomized trials.

Based on our study, we recommend RALPN wherever there is availability of robot and if cost is not an issue.
