Methods: We reviewed all cases of blunt renal injury admitted for nonoperative management at our institution between 1/2002 and 1/2006.

Sutureless laparoscopic heminephrectomy: safety and efficacy in physiologic and chronically obstructed porcine kidney.

We sought to develop and examine the feasibility and efficacy of a streamlined sutureless system of repairing parenchymal and collecting system defects using BioGlue (bovine albumin-glutaraldehyde adhesive) and ProPatch (bovine pericardial patch) in swine under physiological conditions and mechanical stress imposed by chronic ureteral obstruction caused by complete ureteral transaction. Five pigs (10 kidneys) underwent left-side transperitoneal laparoscopic heminephrectomy, followed 2 weeks later by right-sided heminephrectomy with complete ureteral transaction (between clips) to provide a mechanical stressor on the repair, followed 2 weeks later by euthanasia. In each case, after hilar clamping, the lower pole was removed with a bipolar dissector.
