A precise murine model for acute kidney injury (AKI) due to ischemia is an important tool to investigate acute kidney injury and possibly find therapeutic tools to treat renal injury. The hanging weight system offers a tool for immediate and reliable renal artery occlusion and reperfusion without causing renal congestion.

FAQs
Temporary control of the renal artery or vein creates a defined working interval for making a small opening and inserting the catheter. It also helps establish a controlled pathway for blood, saline, or perfusion solutions. Once the cannula is secured, maintaining patency allows measurements or interventions to continue without losing access to renal circulation.
The selected vessel determines how the experiment accesses renal circulation. Arterial or venous placement can provide different opportunities for hemodynamic measurement, blood collection, or compound delivery, while either route may support controlled perfusion studies. The choice therefore depends on the physiological question and the direction of access needed for the planned renal investigation.
Patency keeps the catheter pathway open so blood, saline, or perfusion solutions can move through the system as intended. A maintained pathway supports consistent hemodynamic measurements, collection of renal blood, delivery of compounds, and perfusion of an isolated kidney. Without reliable access, the intended intervention or measurement may not represent the renal response being studied.
The procedure begins by exposing the selected renal vessel and temporarily controlling it. Researchers then create a small opening, insert the catheter, and secure it in position. The final step is maintaining a patent pathway for the planned blood collection, compound delivery, measurement, or perfusion task. These stages establish controlled access while supporting the experiment’s specific objective.
Researchers use this approach when they need direct renal vascular access for hemodynamic measurements, blood collection, compound delivery, or perfusion. It supports investigations of renal function and vascular responses, allowing experimental conditions to be examined through controlled interaction with the kidney’s circulation. The technique is therefore relevant to both physiological research and experimental medicine.
After an isolated kidney is prepared, a renal vessel cannula can provide a route for perfusion solutions and controlled assessment of the organ. This makes the technique useful for studying organ preservation and ischemia-reperfusion injury, alongside broader evaluations of renal function and vascular behavior. The resulting access connects experimental perfusion conditions with measurable renal responses.
