Laparoendoscopic single-site donor nephrectomy

A donor would prefer a minimally invasive procedure because of lesser morbidity, this may be the reason that laparoscopic donor nephrectomy (LDN) rates have exponentially increased. The rationale dictates that a virtually scarless surgery would be most beneficial to this patient subgroup. In this article, we review the approach, instrumentation, dissection and retrieval issues and the results of laparoendoscopic single-site donor nephrectomy (LESS-DN). The existing literature on LESS-DN was reviewed in Pubmed. The various access sites described for LESS-DN include the umbilicus and Pfannenstiel incision. The steps of LESS-DN duplicate those of standard LDN. There is a paucity of studies comparing LESS-DN with LDN, particularly randomized studies. The most challenging step of LESS-DN is graft retrieval. Authors have described a variety of methods for graft retrieval which include manual methods, and those using retrieval bags. In the majority of the studies, the graft retrieval time is longer in comparison to standard LDN. However, the graft outcome in recipients is comparable. In this article, we also allude to the complications mentioned in various series. LESS-DN is currently an evolving procedure. The procedure requires a high level of skills in laparoscopic surgery. The choice of access site, access site ports and the type of instruments to be used is a matter of surgeon preference. Although the warm ischemia time in most of the series is longer in LESS-DN, this has not translated into poor recipient outcomes. Further work needs to be done to make the retrieval quick. Current literature from comparative studies with standard LDN suggests that the results in terms of graft outcome are comparable.
