From: Surgical and functional outcomes of robot-assisted versus laparoscopic partial nephrectomy with cortical renorrhaphy omission

Figure 1

The cortical-renorrhaphy-omitting surgical procedure during partial nephrectomy in this study. In cases without intervention of the renal sinus or urinary tract, the inner suture was omitted and the operation was completed without suturing (a, c). If the renal sinus or urinary tract was opened, an inner suture was performed (b). (a) Tumor resection technique: the renal parenchyma was bluntly dissected along with fiber lines. Bleeding from the cortical or parenchymal vasculature was controlled by soft coagulation. (b) Inner suture technique: opened renal sinuses or urinary collecting systems were closed by running a suture in the parenchymal layer with shallow stitch by 3–0 V-LOC 180 V20 (Covidien; New Haven, CT, USA). (c) Renal cortical hemostasis: cortical renorrhaphy was omitted, and the sheet-type absorbable hemostats (TachoSil; CSL Behring) were onlayed on the tumor bed.
