Study Title | Metabolic changes of the pig kidney during isolated normothermic perfusion with autologous whole blood - urine |
Study Type | Experimental |
Study Summary | This study investigates how glucose, lactate and 20 amino acids in the urine of normothermically perfused pig kidneys changes over time. It also studies how type and severity of ischemia before perfusion (cold or warm ischemia) change this profile. |

Treatment:
Treatment ID: | TR002902 |
Treatment Summary: | Three experimental conditions were investigated (n=6/group): (a) Controls; (b) warm ischemia (WI) simulating hypoxic acute kidney injury; (c) cold ischemia (CI) replicating clinical cold storage. Control kidneys were retrieved, flushed with cold IGL-1, and immediately reperfused. CI group, kidneys were exposed to 22h of CI by submerging them in IGL- 1 (a clinical preservation solution for cold storage) and storing them on ice. In WI, the renal artery and vein were clamped for 60 min before retrieval. In the All kidneys were flushed with 200 ml of Ringer’s solution before mounting them on the ex situ circuit to wash out IGL-1. Because little urine was produced by WI kidneys, too few samples were available for a meaningful analysis. |
Animal Anesthesia: | Pigs were sedated by an intramuscular injection of Tiletamine/Zolazepam (8 mg/kg, Zoletil®, Virbac, Belgium) and Xylazine (2 mg/kg, Xylazine®, VMD pharma, Belgium) to allow orotracheal intubation. Anesthesia was maintained by inhalation of isoflurane (1% Isovet®, Piramal Critical Care B.V., Belgium) and continuous infusion of fentanyl (8 µg/kg, Fentanyl®, Janssen Pharmaceutica, Belgium). |
