[Living donor nephrectomy: open versus laparoscopic technique]

The living donor nephrectomy has to be safe and effective, allowing a good graft function in the recipient. In the past, donor nephrectomy was performed only by open technique; more recently this nephrectomy has also been performed by laparoscopic technique. The best technique has not been established in literature. The purpose of this study is to report the results of open and laparoscopic nephrectomy in living donors. MATERIALS AND METHODS. From January 1992 to August 2008, 37 living donor nephrectomies were performed. 23 nephrectomies were achieved by laparoscopic procedure (LDN) and 14 by open technique (ODN). The 2 groups were comparable regarding both donor and recipient characteristics. RESULTS. All laparoscopic nephrectomies were successfully performed without conversion to open procedure. No donor deaths were reported in either groups. 3 complications (13%) in the LDN group and 1 (7.1%) in the ODN group (p=0.6) were observed. Mean operative time was higher in the LDN group (p<0.036). Mean warm and cold ischemia time, resumption of oral intake and hospital stay were shorter in the LDN group (p<0.04)( p<0.03) (p<0.0001), whereas the return to normal occupational life was similar (p<0.52). We had no significant differences in the surgical complication rates, graft and patient survival. CONCLUSIONS. Our experience suggests that both procedures can be used safely and efficiently, and assure a good renal function in the recipient. Laparoscopic nephrectomy, although more difficult, provides post-operative advantages. However, laparoscopic procedure must be performed by experienced centres only to prevent serious complications in the donor.
