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

Purpose: 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.

Material and methods: A total of 16 hemodialysis patients who underwent LESS nephrectomy (LESS-N; n?=?8) or conventional laparoendoscopic nephrectomy (C-N; n?=?8) between November 2003 and July 2012 were retrospectively evaluated. Outcomes were compared between the two groups.

Results: 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; p?=?.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; p?=?.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.

Conclusions: Although there is a little extension of the operating time, LESS nephrectomy in hemodialysis patients is a feasible procedure compared with the conventional method.
