Analysis of primary urethral wound healing in the rat.

Objective: To analyze the process of urethral healing, which is the basis of urethral reconstructive surgery but remains poorly understood, we have developed a rat model of urethroplasty. Understanding this process may provide strategies to prevent aberrant urethral healing and improve the healing process.

Methods: We performed urethroplasties on 36 male Sprague-Dawley rats.
