[Laparoscopy of the upper urinary tract].

The upper urinary tract is a wide field for using of laparoscopy. The aim of this work was to analyze retrospectively our experience in the development of laparoscopic techniques of surgical treatment of upper urinary tract pathology. 137 patients with pathology of the upper urinary tract were operated laparoscopically in our department during three years (July 2010 - July 2013).

[EEG changes in response to dehydration depending on the extent of intracranial hypertension].

The authors examined 30 patients with intracranial hypertension caused by brain tumor who received 1 g/kg mannitol for dehydration. It was found that dehydration improves the function of the brain in the stage of subcompensation but makes it worse in the stage of decompensation. This has an effect both on the patients' general condition and on the EEG.
