[Oxidation-reduction processes in patients with recurring nephrolithiasis complicated with chronic pyelonephritis and urostasis during combined treatment].

Results of study into the condition of reduction-oxidation processes, in particular of those associated with generation of the superoxide radical, are submitted together with those of determination of levels of inorganic phosphate which is known to be an important indicator of the tissue bioenergy potential, in 112 patients presenting with a recurring form of nephrolithiasis exposed to a multiple-modality treatment that included conventional antiinflammatory and antibacterial therapy plus "open" and endourological operations on kidneys and ureters. The multiple-modality treatment of the main group patients was supplemented with phlogenzyme, a drug of II generation systemic enzymotherapy. An enhanced generation of superoxide radical was recordable having developed in the wake of a steady increase in the activity of xanthinoxidase. The authors have come to the conclusion that the conducted therapeutic intervention, especially as part of systemic enzyme therapy, results in decline of activity of the xanthine oxidation processes and brings about a change in the blood:urine inorganic phosphate concentrations ratio.
