Endo-Satinsky clamp hybrid in situ perfusion in retroperitoneoscopic donor nephrectomy for right-sided kidney

Abstract Objective To introduce our hybrid technique using an endo-Satinsky clamp and in situ cold perfusion for right-sided retroperitoneoscopic donor nephrectomy (RDN) and to investigate efficacy and safety compared with those standard right-sided RDN. Methods This retrospective study included 16 transplant donors who underwent right-sided RDN from January 2016 to January 2018. Donors received either hybrid RDN (n = 6) or standard RDN (n = 10). Perioperative outcomes, including operative time, estimated blood loss, warm ischemic time, hospital stay, length of renal vein obtained as well as postoperative renal function of their recipients were collected and compared between the hybrid RDN and standard RDN groups. Results Procedures were performed successfully in all 16 donors. The hybrid RDN group required longer operation times (135 vs 115 minutes), demonstrated increased blood loss (175 vs 140 mL), but shorter warm ischemic times (1.5 vs 5.5 minutes) and resulted in longer length of the procured renal vein (2.8 vs 1.7 cm) as compared with the standard RDN group. No difference in perioperative complication rates was witnessed between the 2 groups. Also, there were no significant differences in serum creatinine levels and glomerular filtration rates of recipients between the 2 groups at both postoperative day 3 and 1 month. Conclusion The hybrid RDN potentially extends the length of the right donor renal vein. The perioperative outcomes of hybrid RDN were comparable with those of the standard RDN. This hybrid technique can be a technically safe and feasible option for right kidney donation.
