Abstract

Abstract The main role of retroperitoneal tumor diagnosis is the imaging examination. Diagnostic imaging is essential for describing and predicting lesion integrity limits adjacent organs. Methods. The results are based on a sample of 53 patients admitted in the Urology Clinic and investigated during the period 1 January 2005 - 31 December 2014. Results. CT scan for retroperitoneal tumor: vascular tumors are diagnosed in 100% of cases, while endocrine tumors and lymphomas values are between 50-66.67% in terms of a positive diagnosis. In 54.71% of cases studied was identified retroperitoneal tumor invasion into adjacent structures (29 patients), and for 12 cases (22.64%) CT scan was not conclusive enough. CT scan investigation to identify metastasis has statistical significance (p <0.01) according to the different types of retroperitoneal tumors, there were on average 35% for highlighting values of peritumoral lymph nodes and 13% for metastases. The relationship between retroperitoneal tumor size detected by CT (coefficient R =0.736) than those found intraoperative CT examination reveals that tends to underestimate the retroperitoneal tumor size. Conclusions. Imaging diagnosis is mainframe of positive diagnosis for retroperitoneal tumors. CT scanning bring data not only on tumor location, but also about the nature of injuries (cystic or solid), presence or absence of necrosis, invasion of adjacent structures and abdominal metastases.
