Abstract :“Demirtas’ Early Renal Vascular Control Technique insert ignore into journalissuearticles values(DERVACT);” is a novel technique for renal pedicle control that aims to achieve rapid and direct access to the renal artery through the retroperitoneal space and then the superior-dorso-lateral aspect of the kidney. In this study, we aimed to introduce DERVACT and to present the initial outcomes of this technique. This retrospective-observational study compared two groups of patients that were operatively treated by the same surgical team using two different nephron sparing surgery insert ignore into journalissuearticles values(NSS); procedures. Group I insert ignore into journalissuearticles values(n=95); underwent standard open NSS and Group II insert ignore into journalissuearticles values(n=92); underwent open NSS with the DERVACT between Jan 2015 and July 2020. Mean age was 56.42 ± 13.27 years. No significant difference was found between the two groups with regard to age, gender, Body mass index, mass laterality and size, and the Padua and c-index scores insert ignore into journalissuearticles values(p=0.087, p=0.354, p=0.642, p=0.957, p=0.200, p=0.101, p=0.361, respectively);. Similarly, no significant difference was found between the DERVACT group and the other group with regard to ischemia duration insert ignore into journalissuearticles values(20.0 [15.0-30.0] min vs. 18.5 [11.0-27.0] min, respectively, p=0.060); and intraoperative vascular complication rate insert ignore into journalissuearticles values(6.3% vs. 1.1%, respectively. p=0.059);. However, non-ischemic operative time was significantly shorter in the DERVACT group than in the standard partial nephrectomy group insert ignore into journalissuearticles values(64.0 [50.0-75.0] vs. 84.0 [61.0-105.0], p<0.001);. As a conclusion, DERVACT is a simple, time-saving, and safe procedure for NSS that can be used in clinics with no opportunities for robotic-laparoscopic partial nephrectomy or in open partial nephrectomy.
