Polymer clips (Hem-o-lok®) for Renal Vessel Control in Laparoscopic Living Donor Nephrectomy: 12 years of experience in a Tertiary Care Center

Objective: To describe our experience using polymer clips (Hem-o-lok®) for renal vessel control in laparoscopic living donor nephrectomy (LLDN).
 Materials and methods: We conducted a retrospective descriptive analysis from database of all minimally invasive nephrectomies (hand-assisted pure laparoscopic) performed 2008 to 2020 institution. included patients who underwent LLDN vascular arteries veins, whose clinical records were complete.
 Results: 330 performed, 183 (55.5%) hand-assisted 147 (44.5%) nephrectomies. Mean warm ischemia time (WIT) was 3.98 minutes median estimated blood loss (EBL) 100±140 ml. Four (1.2%) required conversion an open procedure due injury. 31 complications (9.3%) registered, which 23 (6.9%) non-life-threatening complications. No deaths nor grafts reported.
 Limitations: the main drawbacks this study are its nature, that it is limited only one center.
 Originality value: It questions contraindication issued by FDA use LLDN, demonstrating safe effective option.
 Conclusion
 The clips, specifically Hem-o-lok®, method hilum vessels
