Laparoendoscopic single-site nephrectomy for hemodialysis patients with dialysis-related renal tumors.

<bold>Purpose:</bold> The purpose of this study is to assess the efficacy of laparoendoscopic single-site (LESS) nephrectomy in hemodialysis patients, we compared outcomes between LESS nephrectomy and conventional laparoendoscopic nephrectomy in hemodialysis patients with dialysis-related renal tumors. <bold>Material and methods:</bold> A total of 16 hemodialysis patients who underwent LESS nephrectomy (LESS-N; <italic>n</italic> = 8) or conventional laparoendoscopic nephrectomy (C-N; <italic>n</italic> = 8) between November 2003 and July 2012 were retrospectively evaluated. Outcomes were compared between the two groups. <bold>Results:</bold> Patient and tumor characteristics were similar between the LESS-N and C-N groups. The mean operative duration was longer in the LESS-N than in the C-N group (231.0 ± 26.7 min versus 188.6 ± 36.4 min; <italic>p</italic> = .025). The mean estimated blood loss was lower in the LESS-N compared with the C-N group (26.4 ± 14.4 ml versus 65.6 ± 45.2 ml; <italic>p</italic> = .047). Postoperative complications were observed in three cases, comprising one case of retroperitoneal hematoma in the LESS-N group and one case each of peritoneal hematoma and retroperitoneal abscess in the C-N group. Surgical scarring was minimal in the LESS-N group. <bold>Conclusions:</bold> Although there is a little extension of the operating time, LESS nephrectomy in hemodialysis patients is a feasible procedure compared with the conventional method.
