[Effects of calculi structure on the results of ESWL lithotripsy].

Structure of stones influences effects and sequelae of extracorporeal shock-wave lithotripsy (ESWL). Clinical sequelae of ESWL in oxalate stones are the worst because of the fragments size and physical qualities of these stones. Oxalates are firm and sharp. Such qualities may cause injury and swelling of the ureter when the fragments pass it. A JJ stent and catheter are proposed to prevent complications of oxalate stone ESWL in the stones size more than 1.5 cm.
