New technique with combination of felt, Hem-o-lok and Lapra-Ty for suturing the renal parenchyma in laparoscopic partial nephrectomy

Abstract

We reported a new technique for closure of the renal parenchyma in laparoscopic partial nephrectomy, shortening the suturing time. Between 2009 and 2011, 41 patients with renal masses 4cm or smaller in diameter underwent transabdominal laparoscopic partial nephrectomy by a single surgeon in a single institution. The sutures were carried out using 2-0 vicryl CT-1 with a 1.2×1.2cm piece of felt, and both sutures were temporarily held using a Hem-o-lok. After all sutures (median 3) were completed, they were sequentially fixed by sliding the Hem-o-lok, and then locked using the Lapra-Ty. The median times for suturing the renal parenchyma and ischemic time were 13min and 28min, respectively. The arrangement of the wound and hemostasis were good. No patients developed urinoma or postoperative bleeding. © 2011 The Japanese Urological Association.
