Safety and efficacy of a surgeon-prepared gelatin hemostatic agent compared with FloSeal for hemostasis in laparoscopic partial nephrectomy.

Background And Purpose: Postoperative hemorrhage is a significant risk after laparoscopic partial nephrectomy (LPN). Hemostatic agents have become increasingly popular as adjuncts to renorrhaphy because of their potential to minimize intracorporeal suturing and lessen warm ischemia time. The objective of our study was to compare the safety and efficacy of an inexpensive, surgeon-prepared hemostatic agent with that of a more expensive, commercially prepared one.
