Siddighi S, et al. - Authors sought to present a simple method that screens for ureteral injury in the acute postoperative period after urogynecologic surgeries. It was noticed that a small change in serum creatinine level over baseline after urogynecologic surgery alerted the possibility of ureteral injury or obstruction. A simple and inexpensive evaluation of perioperative creatinine levels seemed to have the potential for predicting ureteral damage promptly in the acute postoperative period for gynecologic reconstructive surgeries.
