[Extracorporeal shock-wave lithotripsy in the treatment of patients with coral-like nephrolithiasis].

An analysis was performed of results of treatment with extracorporeal shock-wave lithotripsy (ESWL) of 57 patients with coral-like nephrolithiasis (CLN), a total of 151 sessions. The policy of dealing with the patients has been worked out in conducting ESWL as related to the stage of formation, mineral composition of the coral-like calculus, functional condition of the kidneys, phase of the inflammatory process, condition of the urinary tracts, as well as to the indications for draining. Efficiency is shown of ESWL depending on the stage of formation of the coral-like calculus.

[The proteolysis-ion theory of the pathogenesis of nephrolithiasis].

A study was made of urinary proteolysis. This parameter turned to be decreased in patients with nephrolithiasis versus normal subjects. The authors developed an original proteoclastic-ion theory of nephrolithiasis pathogenesis, based on the two main risk factors triggering the disease: low levels of urinary proteolysis leading to the formation of a calculous matrix; the urine pH values optimal for the sedimentation of lithiasic salts.
