We studied morphobiomechanical properties of the ureters of 134 adult people, results of treatment of 178 patients suffering from ureterolithiasis which were divided into two groups: the comparison group (n = 97) in which contact lithotripsy was carried out without power dosage lithotripter and the study group (n = 81) in which stone decomposition results were analysed with account of impulse duration and power of the shock wave estimated with special tables for an individual patient. We developed expert tables presenting optimal regimens for power pneumatic lithotriptor for fragmentation of a concrement with the least traumatic effect taking into account sex, age of the patient, size, chemical composition and location of the concrement. The above expert tables can be used in urological departments practicing contact ureterolithotripsy for ureterolithiasis, and in medical high schools for teaching students.
