Uninterrupted suturing of renal parenchyma in laparoscopic partial nephrectomy decreases renal ischemic time and intraoperative blood loss.
We examined factors affecting renal ischemic time and intraoperative blood loss in laparoscopic partial nephrectomy and attempted to determine which method of suture for parenchymal closure is effective in this operation. Fifty-seven patients who underwent laparoscopic partial nephrectomy were studied. Some variables and methods of suture for parenchymal closure were tested for independent effects on ischemic time and bleeding volume. Mean renal ischemic time and estimated blood loss were 38 min and 175 mL, respectively. Method of suture for parenchymal closure was the only factor independently associated with intraoperative blood loss less than 100 mL. Furthermore, uninterrupted suture for parenchymal closure was a significant factor associated with renal ischemic time less than 30 min. Renal ischemic time or intraoperative blood loss can be decreased by using uninterrupted suture for parenchymal defect.
