Safety and efficiency of unidirectional barbed suture for laparoscopic partial nephrectomy

Objective To evaluate whether the unidirectional barbed suture is safety and efficiency enough for laparoscopic partial nephrectomy.Method From March 2013 to March 2014,27 patients with renal mass have been involved into this study and divided into 2 groups wsing a lottery.Group A used Coated Vicryl in renorrhaphy after LPN,and group B used unidirectional barbed suture.All patients underwent LPN preformed by single group of surgeons.Perioperative and postoperative indicators were compared in two groups.Result It is identical in age,BMI,tumor size,R.E.N.A.L nephrometry scoring system between 2 groups.However,using barbed suture has significantly shortened in warm ischemia time (WIT).The postoperative indicators,such as blood loss,hospital stay and surgery complication has no significantly difference in two groups.Conclusion The unidirectional barbed suture is safety and efficiency using in LPN which can shorten WIT significantly.
