Purpose: Laparoscopic living donor nephrectomy (LLDN) has been reported to be as safe and effective as open surgery. We systematically evaluated the safety of video-assisted minilaparotomy surgery-living donor nephrectomy (VAMS-LDN) with use of the modified Clavien classification. Materials and Methods: We retrospectively analyzed complications in 720 cases of VAMS-LDN conducted in our institute from 2003 to 2010 by use of the modified Clavien classification of surgical complications. Results: The mean age of the donors was 39.3 years (range, 16 to 66 years) and their mean body mass index was 23.3 kg/m 2 (range, 15.8 to 36.4 kg/m 2). A total of 67 complications occurred (9.3%). Based on the modified Clavien classification, grade 1, 2a, and 2b complications occurred in 49 (6.8%), 16 (2.2%), and 2 (0.3%) of the donors, respectively. Most grade 1 complications involved mild vascular injuries that were immediately repaired with polypropylene sutures during the surgery. These did not cause any postoperative problems. The other grade 1 complications were wound dehiscence, not requiring secondary closure, and wound site pain in 11 (1.5%) and 5 (0.7%) cases, respectively. Grade 2a complications occurred in 16 (2.2%) cases: 9 (1.3%) involved postoperative transfusions and 1 (0.1%) involved a renal fossa hematoma. One grade 2b complication occurred; it was a lymphocele that resolved with placement of a pigtail catheter. No complications classified as grade 2c or worse occurred. Conclusions: According to the present analysis of complications, VAMS-LDN is a safe procedure with complication rates comparable to those of LLDN as evaluated in previous studies.
