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.

2025
This protocol presents a novel coronoid-temporalis pedicled flap (CTPF) technique for reconstructing small-to-medium orbital floor defects. CTPF avoids microvascular risks while maintaining biomechanical stability. Clinical cases demonstrate effective structural restoration, reduced complications, and preserved facial symmetry, offering a viable alternative to traditional grafts or alloplastic materials.

Early stage hemodynamic dysfunction is critical to the development of kidney disease. Yet, detection methodologies are limited. Recent advances in sonography provide a noninvasive, accurate option for early detection of kidney injury. This study outlines a step-by-step, sonographic methodology for detecting kidney dysfunction using a drug-induced nephrotoxicity rat model.
FAQs
The clamp controls both arterial inflow and venous outflow at the renal pedicle, reducing perfusion within the operative kidney. This limits bleeding and creates a clearer field for precise tissue removal or repair. Its value lies in providing temporary control that can be reversed after the targeted surgical work is completed.
Clamping temporarily reduces the kidney’s blood supply, producing warm ischemia while the organ remains at body temperature. Releasing the clamp restores circulation, creating reperfusion. These two phases are central to evaluating the balance between operative control and preservation of renal function, particularly when surgery requires careful handling of functioning kidney tissue.
Preserving functioning nephrons is an important objective because the procedure is not judged only by bleeding control or successful tissue removal. Surgical planning must also consider how temporary vascular occlusion affects the remaining viable kidney tissue. This emphasis connects pedicle control with broader efforts to maintain renal function after kidney operations.
The surgical sequence consists of controlling the renal artery and vein, performing the planned removal or repair while perfusion is reduced, and then releasing the clamp to restore circulation. This ordered workflow provides a controlled operative interval while making restoration of renal blood flow an explicit part of completing the procedure.
Partial nephrectomy is the most common setting identified for this technique because surgeons must remove targeted tissue while maintaining control of bleeding. It can also support other kidney operations requiring precise tissue handling. In each setting, the method is relevant when a temporary bloodless field helps the surgeon work accurately.
The technique provides a framework for studying how surgical control, warm ischemia, reperfusion, and nephron preservation interact. Research can therefore focus on strategies that maintain a sufficiently controlled field while limiting effects on functioning renal tissue. This makes pedicle clamping relevant to efforts aimed at improving the safety of renal procedures.
