OBJECTIVE:
In laparoscopic donor nephrectomy (LDN), technical problems are less common in the right side than in the left side. In addition, several study series have shown initially high rates of complications and graft loss in left LDN with multiple renal arteries. The objective of this study was to assess the effect of right LDN and left renal artery multiplicity, especially 3 renal arteries, on donor and recipient outcomes after retroperitoneoscopic LDN (RPLDN).
METHODS:
During a 12-year period, 764 patients underwent living-donor renal transplantations with allografts procured via RPLDN at our institute. Of the patients, 32 (4.2%) and 30 (3.9%) had right (R group) and 3 left renal arteries (L3 group), respectively. Surgical renovascular reconstructions were performed in patients with multiple renal arteries.
RESULTS:
The total ischemic time in the L3 group was significantly longer than that in the R group. No significant differences were observed between the R and L3 groups regarding operative time, blood loss, warm ischemic time, hospital stay, and early graft function (Tables 1 and 2).
R group (n=32) | L3 group (n=30) | P value | |
Operative time (min) | 304 ± 69 | 330 ± 89 | 0.202 |
Blood loss (g) | 51 ± 52 | 68 ± 81 | 0.326 |
WIT (min) | 6.1 ± 1.9 | 5.7 ± 2.5 | 0.479 |
TIT (min) | 101 ± 28 | 137 ± 32 | <0.001 |
Hospital stay (days) | 4.0 ± 1.1 | 4.5 ± 2.1 | 0.241 |
R group (n=32) | L3 group (n=30) | P value | |
SGF (%) | 1 (3.1) | 4 (13) | 0.156 |
DGF (%) | 0 | 0 | – |
sCr at POD 7 (mg/dl) | 1.9 ± 1.7 | 1.5 ± 0.7 | 0.374 |
sCr at POD 14 (mg/dl) | 1.8 ± 1.4 | 1.5 ± 0.7 | 0.846 |
The right and left kidneys with 3 renal arteries had similar excellent outcomes after RPLDN.
