Investigation Of The Closing Forces Involved In Re-Approximation Of The Renal Remnant Following Partial Nephrectomy, Donald M. Endres Ii

Masters Theses

Partial nephrectomy has become the preferred method of treatment in certain renal diseases, including small, peripheral tumors. However, re-establishment of hemostasis in the remaining tissue remains a challenging procedure. To better understand the forces involved in re-approximation of the renal remnant, this study measures the suture tensions reached in sliding clip renorrhaphy, as well as the ability of the tissue to support those tensions, and reviews how long suture material might be expected to survive those forces.

Three separate groups of experiments were conducted on fresh, porcine kidney tissue. Treatment groups were compared using commercially available software to compute appropriate …
