Features of examination of patients with kidney and ureter injuries

The aim of the study was to assess the capabilities of magnetic resonance imaging (MRI) in the diagnosis of complications in patients with combined kidney and ureteral injuries during different periods of traumatic disease. The observation group included 139 patients aged from 18 to 72 years with renal and ureteral injuries, who were injured in traffic accidents. Complications of renal trauma occurred in 74 of 128 patients with isolated and combined injuries (59.2%), strictures were observed in 9 of 11 patients with ureteral trauma in the late period, and 1 of them had a failure of vesicoureteral anastomosis. The most common complication in the early and late periods of traumatic disease, occurring in 25.0% of cases, was pyelonephritis; patients with abscesses (12.5%) and acute renal failure (11.7%) were also common. The methods of choice for the diagnosis of combined injuries in the acute period were: ultrasound examinations according to the eFAST protocol and multislice computed tomography according to the “Polytrauma” protocol. Multiparametric magnetic resonance imaging (mpMRI) of the kidneys and ureters was indicated in the periods of early and late manifestations of traumatic disease to detect renal complications when there is a discrepancy between clinical data, ultrasound and multislice computed tomography (MSCT) findings, and there are contraindications for MSCT with intravenous contrast.
