Table 3 Comparison of outcome between KT recipients with SRA and MRA. The ischemic time was longer in the MRA group, but no significant differences in blood loss, complications, graft loss, and recipient death were detected.
| Parameter | SRA | MRA | p-value |
|---|---|---|---|
| Total operation time (minutes), median (IQR) | 376.5 (332.0–451.0) | 465.0 (354.0–563.0) | <0.0001* |
| Warm ischemic time 1 (minutes), median (IQR) | 6.0 (5.0–7.0) | 8.0 (6.5.0–11.0) | <0.0001* |
| Cold ischemic time (minutes), median (IQR) | 27.0 (21.0–41.0) | 59.0 (47.0–69.5) | <0.0001* |
| Warm ischemic time 2 (minutes), median (IQR) | 62.0 (53.0–72.0) | 67.0 (52.5–98.0) | 0.143* |
| Total ischemic time (minutes), median (IQR) | 97.0 (86.0–122.0) | 131.0 (115.0–175.5) | <0.0001* |
| Blood loss (mL), median (IQR) | 230.5 (124.5–451.5) | 290.0 (127.5–439.0) | 0.678† |

| * Fisher exact test. KT – kidney transplant; SRA – single renal artery; MRA – multiple renal arteries; IQR – interquartile range. | |||
