Minimally Invasive Partial Nephrectomy: Are All Clamps Created Equal? An Ex Vivo Model Simulation of Vascular Clampage

Abstract

During the partial nephrectomy, clamping of the vascular pedicle before exision of the tumor is a key step in minimizing blood loss and maintaining adequate visualization. Different vascular clamping devices have been developed for minimal invasive surgery. However, there are no reports comparing them in turn of efficiency RECENT FINDINGS: We present an ex vivo experimental model, designed to demonstrate differences between the clamping devices. All clamps proved to function properly without any leakage at 90 and 120 mmHg, respectively. Our study and the ex vivo model prove that all available clamps are equally efficient at physiologic pressures.
