There were a number of shortcomings with these trials, both individually and collectively. All were inadequately powered to detect clinically significant differences in many of the outcome measures. Given the reported frequency of major complications and perioperative mortality (0.03%),2–3 randomized controlled
trials do not appear feasible in resolving these major safety issues due to the large number of subjects required. A further shortcoming of these trials was the fact that in three out of the five series,19,21,24 Z-VAD-FMK order right kidneys (which are more technically challenging) were excluded, thus reducing the potential relevance of the studies to routine clinical practice in which up to 25% of live donor transplants involve the right kidney.27 Moreover, only one of four studies reported a reduction in duration of hospitalization with laparoscopic
nephrectomy.19 The remaining series reported no difference compared with open surgery.21,23,24 Overall, the series indicate that laparoscopic nephrectomy is associated with reduced analgesic requirements, increased warm ischaemia times (although without impact on graft function) and longer operative times. The relevance of the latter finding is uncertain as differences between series with the same operative technique were greater than those seen within series comparing the two techniques.No data were provided with regards to re-admission rates in any of the studies and in three studies, Maraviroc cell line details were scant regarding intraoperative and postoperative complications. Cost comparison was an outcome measure in one randomized controlled trial.19 Mean operating room costs for the laparoscopic group were
161% greater than for the open surgical group, relating to increased operative times and additional equipment Clomifene expenses. The latter accounted for only 24% of the operative costs for open surgery compared with 61% for laparoscopy. This series reported a shorter hospital stay in the laparoscopic group, which offset some of the increased operative costs such that mean hospital cost was 24% greater in the laparoscopic group. The loss of occupational income for laparoscopic donors during their convalescence was 75% that of the open surgical donors. As a result, the global cost of the nephrectomy, which included the total hospital costs and loss of occupational income, was not significantly different between the two groups (2% greater in the laparoscopic group.) Several techniques have been described for laparoscopic donor nephrectomy – as a purely laparoscopic approach either transperitoneally or extraperitoneally or as a hand-assisted transperitoneal approach. In the USA, both pure laparoscopic and hand-assisted approaches appear to be used equally.
