[The clinical laboratory evaluation of impact of shock wave on the activity of peptidohydrolase in urine of patients with urolithiasis].

The article presents the results of comprehensive clinical biochemical study of 79 patients with urolithiasis admitted to the urologic department of public clinical hospital No 7 in 2007-2009. The diagnostic evaluation of the impact of shock wave on kidney parenchyma and crystallization processes was implemented. The chromatography-mass spectrometry was applied to analyze the activity of hydrolytic enzymes in urine of patients with urolithiasis underwent the remote lithotripsy sessions. The dependence of the peptidohydrolase activity alteration in urine of patients with urolithiasis after remote lithotripsy from presence/absence of concomitant pyelonephritis was substantiated. This outcome permitted not only to implement the laboratory-based prevention during the pre-operational stage but to plan properly the ratio of repeated sessions of lithotripsy.

[Role of an infectious factor in the pathogenesis of urolithiasis].

The paper gives the data of complex clinical and biochemical examination in 122 urolithiasis (ULT) inpatients treated at the Urology Unit, Moscow City Clinical Hospital Seven, in February 2004 to January 2008. The levels of lithogenic substances and compounds, inhibitors and activators of lithogenesis have been determined. The authors show it possible to use the level of hydrolytic enzymes and activators of cooperative microbial sensitivity as diagnostic and prognostic criteria in diferent forms of ULT, which is in turn of no small importance in developing the science-based methods for the treatment and prevention of recurrent lithogenesis.
