Objective: To investigate the effect of epidermal growth factor (EGF) on fibrous tissue formation and wound healing in experimental pelviureteral anastomosis (PUA). Materials and Methods: Twelve rabbits were divided equally into 2 groups: control (C) and epidermal growth factor (EGF). A 1-cm length of the ureteropelvic segment was resected through a laparotomy incision and then anastomosis was performed. The rabbits were administered locally with 100 μg/kg EGF (EGF group) all around the anastomosis lines after the surgical procedure. The C group did not receive any medication during their procedure. Intravenous pyelography was carried out on postoperative day 21. The rabbits were sacrificed and dissected under a dissecting microscope and examined for acute inflammation (AI), chronic inflammation (CI), granulation tissue amount (GTA), granulation tissue fibroblast maturation (GTFM), collagen deposition (CD), neovascularization (N), re-epithelization (R), and peripheral tissue reaction (PTR) in the anastomosis lines 3 weeks later. Results: There were no significant differences in the GTA, N, or R scores in the C group compared with those in the EGF group. In the EGF group, AI and CI scores were lower than they were in the C group. CD, GTFM, and PTR in the EGF group were higher than they were in the C group. Conclusion: EGF did not decrease CD, GTFM, or PTR, but did decrease important parameters in wound healing such as acute inflammation and chronic inflammation in an experimental model of PUA in rabbits. |
