This study was designed to evaluate whether a microfibrillary collagen hemostatic agent (Avitene) would cause retroperitoneal fibrosis and ureteric obstruction when applied along the side of the ureter and left in situ for a period of 6 months. The contralateral side served as a control. Serial intravenous urograms were obtained and histopathologic studies were conducted to evaluate these effects. No evidence of significant retroperitoneal fibrosis or ureteric obstruction was found either on serial intravenous urograms or on histopathologic examination of the ureter after 6 months.
本研究旨在评估一种微纤维胶原止血剂（爱维治）沿输尿管侧方应用并原位留置6个月时是否会导致腹膜后纤维化和输尿管梗阻。对侧作为对照。通过连续静脉肾盂造影以及组织病理学研究来评估这些影响。6个月后，无论是连续静脉肾盂造影还是输尿管的组织病理学检查，均未发现明显腹膜后纤维化或输尿管梗阻的证据。
