A Review on Bladder Wound Healing after Mechanical Injury

Congenital defects of the urinary bladder that requires surgical intervention with mechanical wounding are common situations among pediatric urology patients. In conditions with severe lack of tissue, regenerative medicine with autologous cells has become a field of interest for future cure. In both situations, normal bladder wound healing is of major importance for an uneventful healing process and for the final results. Much effort has been put into increasing our understanding in the area of urinary bladder wound healing. Several methods have been used in different studies, all representing different clinical settings to address the issue of normal healing. However, little is known about the differences between these different wound-healing models. In this review, we aimed at summarizing what is known about the process of bladder wound healing after mechanical injury. We present the most commonly used methods in this area; describe the process of healing and the current knowledge on involved signaling transduction factors.
