Use of exogenous material to bolster closure of the parenchymal defect following partial nephrectomy.

摘要

Closure of renal parenchymal defects created by partial nephrectomy can be difficult. We describe a method of using exogenous material to bolster the strength of the parenchymal closure. The horizontal mattress sutures closing the renal parenchyma are less likely to tear through the parenchyma as the result of the application of a more uniform tension across a broad front. This technique is particularly helpful for large and irregular defects. Tying the closure sutures over an exogenous bolster material aids in a rapid, hemostatic, and watertight closure.
