[Quantitative phase imaging (QPI) of peripheral blood platelets for evaluation of thrombotic and hemorrhagic complications in patients with staghorn kidney stones after PCNL].

Introduction: An evaluation and prognosis of complications of different treatment options in patients with staghorn stones are necessary to choose optimal surgical strategy and perioperative prophylaxis on individualized basis. Intra- and postoperative thrombotic and hemorrhagic complications are not still well-studied in modern operative urology.

Aim: To explore the influence of morpho-densitometry changes of blood platelets on perioperative thrombotic and hemorrhagic complications in patients with staghorn nephrolithiasis after percutaneous nephrolithotomy (PCNL).

White matter spinal tracts impairment in patients with degenerative cervical myelopathy evaluated with the magnetization transfer saturation MRI technique.

Study Design: Prospective case-control study.

Objectives: We investigated the use of the magnetization transfer saturation (MTsat) technique to assess the structural integrity of the spinal cord tracts in individuals with clinically significant degenerative cervical myelopathy (DCM) and associated disability.

Setting: Novosibirsk Neurosurgery Centre, Russia.

Evaluation of the structural integrity of different spinal cord tracts with magnetization transfer ratio in degenerative cervical myelopathy.

Purpose: Degenerative cervical myelopathy (DCM) is a common cause of spinal cord dysfunction. In this study, we explored the potential of magnetization transfer ratio (MTR) for evaluating the structural integrity of spinal cord tracts in patients with clinically significant DCM.

Methods: Fifty-three patients with DCM and 41 patients with cervical radiculopathy were evaluated using high-resolution cervical spinal cord magnetic resonance imaging (MRI), which included the magnetization transfer technique.

Brainstem and subcortical regions volume loss in patients with degenerative cervical myelopathy and its association with spinal cord compression severity.

Background: In recent years, structural and functional reorganization of the brain and changes in brainstem structural connectivity have been shown in patients with degenerative cervical myelopathy (DCM). We hypothesized that volume loss in the basal ganglia, thalami, and brainstem structures exists and is associated with spinal cord compression severity in patients with DCM.

Methods: Forty-seven patients with DCM and 25 patients with cervical radiculopathy were evaluated using cervical spinal cord and brain magnetic resonance imaging (MRI).
