The aim of this study was to evaluate the effectiveness of MRI in diagnosing combined renal and ureteral injuries at different periods of traumatic disease (TD).
Methods and Results: We analyzed the results of diagnostics and treatment of 139 patients (80 women and 59 men) with renal and ureteral injuries aged between 18 and 72 years. There were 67(48.2%) patients in the period of acute reaction to trauma, 40(28.8%) patients with early manifestations, and 32(23%) patients in the period of late manifestations. In 127(91.4%) patients, an urgent plain abdominal X-ray was performed without any preliminary preparation. USI of the abdominal and retroperitoneal space was performed in 108(77.7%) patients in the stage of the primary assessment of renal injury as it was a rapid non-invasive investigation. A whole-body MSCT was performed in 131(94.2%) patients, using the nonionic contrast agents Ultravist (350mg I/ml) and Omnipaque (350mg I/ml). MRI was performed in 125(89.9%) patients, including cases of pregnancy and a medical history of allergies. Contrast-enhanced MSCT had a high diagnostic efficiency in assessing complications in kidney and ureteral injuries at different periods of TD (accuracy of 89.2% for acute reaction, 88.8% for early manifestations, and 89.5% for late manifestations). MRI of the kidneys and ureters was indicated in periods of early and late manifestations of TB to detect renal complications in cases with a discrepancy between clinical manifestations and the results obtained by ultrasound and MSCT (accuracy of 87.5% for early manifestations and 89.9% for late manifestations).
