The coronavirus pandemic has had a severe impact on the health care system. It is also changing the appointment and conduct of diagnostic procedures, emergency and routine medical care. According to the medical guidelines of the European Society of Urology (EAU) for the provision of urological care during the current epidemic situation, various levels of urgency have been proposed for diagnostic and therapeutic measures depending on the type of disease. Urodynamic studies refer to studies with a priority level from P2 (for neurogenic dysfunction of the urinary tract) to P4 (for lower urinary tract dysfunction without the risk of damage to the upper urinary tract). The question arises regarding the safety of these studies, both for patients and medical staff, and possible measures to reduce the risk of infection in a viral pandemic. Because of the increased workload of hospitals that have not been redesigned for the fight against coronavirus infection and provide routine and emergency urological care, an even greater need has arisen to find effective and safe methods of local anaesthesia for performing urodynamic studies and intradetrusive injections of botulinum toxin type A under local anesthesia in outpatient and outpatient settings (for example, in a short-term hospital). This article presents a literature review on the principles and features of performing urodynamic studies in the context of the Covid-19 pandemic and the effectiveness and safety of using various methods of local anaesthesia when performing intradetrusor injections of botulinum toxin with detrusor hyperactivity of a neurogenic and non-neurogenic nature. There were evaluated forms of local anaesthesia such as intradetrusor instillation of lidocaine, electrophoresis, and the use of alternative solutions for urinary bladder irrigation (for example, Ringer’s solution).

Aim of the study. Clarification of the functional and diagnostic significance of topography, or the type of fMRI-response recorded during active and passive hand movements in patients after traumatic brain injury.Material and methods. fMRI-responses gained during active and passive hand movements were analyzed in 40 patients with posttraumatic motor function disturbances and compared with results gained from 17 healthy volunteers (control group ).Results. In analyzed patients the increase of percentage of diffuse fMRI-response has been shown along with the areas of activation not typical for movement activation pattern typical healthy volunteers. The fMRI response type being it local or multifocal does not clearly correlate with the presence of motor function impairment (hemiparesis). However, it was found that with greater severity of hemiparesis there is a larger percentage of multifocal fMRI-response.The transition from a multifocal form of a motor fMRI-response to a local one observed in a dynamic study is accompanied by an improvement of patient’s general condition, a shift towards normalization of a number of morphofunctional indicators of the central nervous system, the tendency of regression of motor disorders.Conclusion. The increase of multifocal fMRI-responses in patients after traumatic brain injury is one of the signs of cerebral dysfunction. Dynamically observed transformation from multifocal to local fMRI-responses is associated with current or long-term improvement in motor activity as well, wit the regression of other clinical impairments and can be considered as prognostically positive sign of the course of post-traumatic illness.
