Idiopathic retroperitoneal fibrosis:a clinical analysis of 27 cases / 中国普通外科杂志

ABSTRACT

Objective To investigate the clinical characteristics of idiopathic retroperitoneal fibrosis (IRF) and its diagnosis and treatment. Methods Data of 27 IRF cases admitted into our hospital during recent 8 years were retrospectively analyzed. Result The main clinical manifestations of IRF included abdominal pain, lumbago, mass in retroperitoneal cavity and ureteral obstruction. The main diagnostic approach to IRF was the image examination. Preoperative correct diagnosis was established in 85 2% of cases. Ureterolysis and wrapping up with the omentum was performed in 21 cases of ureteral obstruction. Two cases suffering from renal artery (RA) stenosis were relieved with arteria renalis lysis. One superior mesenteric artery (SMA) stenosis was managed by arterial lysis. Twenty six cases were cured and one case died postoperatively. Conclusion IRF has nonspecific clinical manifestations. The preoperative diagnosis depends on the image characteristics. The treatment mainly consists of the relief of the obstructive symptoms.
