Impact of multiple renal arteries on outcomes of renal donors and recipients in hand-assisted retroperitoneoscopic donor nephrectomy

Abstract

Objective To analyze the clinical efficacy of multiple renal arteries on outcomes of renal donors and recipients in hand-assisted retroperitoneoscopic donor nephrectomy. Method From 2012 to 2014, 121 patients underwent hand-assisted laparoscopic donor nephrectomy, including 92 cases of a single renal artery and 29 cases of multiple arteries. Donor and recipient outcomes for single artery and multiple arteries allografts were compared. Result The study included 121 pairs of donors and recipients. The demographic characteristics between multiple renal artery group and single renal artery group had no significant difference. The operative time, blood loss, postoperative complications, and hospital stay had no significant difference between two groups. Cold ischemia time and warm ischemia time in multiple renal artery group were longer than single donor renal artery group (128.5±13.2 vs. 50.2±17.3 min, P<0.001; 196.0±63.3 vs. 154.1±55.2 min, P=0.002, respectively). The operative time in multiple renal artery group was longer than in single renal artery group (213.5±28.2 vs. 182.2±31.1 min, P<0.001). There was no significant difference in blood loss, vascular complications and ureternal complications between two groups. The renal functions of two groups were likewise within one year. Conclusion There was no statistically significant difference in clinical efficacy between hand-assisted retroperitoneoscopic donor nephrectomy with multiple renal arteries and single artery. The use of these grafts was safe for both recipients and donors. Key words: Retroperitoneoscope; Kidney transplantation; Living donor; Renal artery
