title: [Extracorporeal shockwave lithotripsy in patients with the long-term presence of stones in the ureter].
abstract: 28 patients with long-standing ureteroliths (present in the ureter for 2 months and longer, size 0.8-1.5 cm) were exposed to extracorporeal impulse lithotripsy (EIL). 26 of them were found to have inflammation in the kidneys and upper urinary tracts. Comparative data on EIL effect show that patients with long-standing ureteroliths need more intensive and long EIL treatment, that fragmentation is more troublesome in oxalate monohydrates and phosphate stones with hydroxylapatite. 4 cases eventuated in operative intervention, in 3 cases ureterolith extraction was performed. EIL results in long-standing ureteroliths depend on the presence of renal and urinary tract inflammation, severity of periureteritis, chemical composition, density and structure of the stones.
