Objective: To evaluate the effect of the bar-bed and the conventional absorbable sutures for renorraphy on the outcomes of robot assisted partial nephrectomy (RAPN).
Material and Methods: Between 2009 and 2011, a total 38 patients with a renal mass who underwent RAPN were included in this study. Of 38, renorraphy was performed with a poly-glactin suture in 16 patients (Group 1) and, with a barbed polyglyconate suture in 22 pati-ents (Group 2). The mean operative time, es-timated blood loss (EBL), warm ischemia time (WIT), hospital stay, complications and oncolo-gic outcomes were evaluated prospectively.
Results: There was no statistical difference between groups in terms of age, gender, comor-bidities and tumor characteristics. The mean operative time was 163± 55 min in Group 1 and 137 ± 18 min Group 2 (p=0,001). The mean EBL was 472 ± 540 ml in Group 1 and 185± 110 ml in Group 2 (p=0,001). The mean decline in hematocrit was %6.43 ± 3.4 in Group 1 and %3.82 ± 2.7 in Group 2 (p=0.015). The WIT was 28.7 ± 9.3 min and 20.9 ± 6.9 min (p=0.005) in Group 1 and 2, respectively. The mean follow up was 24 and 18 months in Group 1 and 2, res-pectively. No tumor recurrence has occurred in both groups at the follow-up.
Conclusions: Utilization of barbed sutures for renorraphy during RAPN facilitates rapid, safe and potent renal parenchymal repair. Re-norraphy with barbed suture results in reduced warm ischemia time and blood loss.
Key Words: kidney, cancer, robot, partial nephrectomy
