[The characteristics of ureteral lithiasis]

The study covers 2630 patients with ureteral concrements, eliminated operatively, through extracorporeal lithotripsy (ESWL), or spontaneously as the result of drug treatment. Attention is called to the left-side location of ureteral concrements, regardless of the mode of elimination, with the clinical symptomatology of the disease being comprehensively discussed. Clinical and chemical characterization of ureteral concrements (type, size and the like) is also done separately with a special reference to the method of removal employed. In concrements eliminated spontaneously a correlative dependence with the annual season is sought; in the winter months a rather elevated frequency of elimination is recorded, irrespective of the type of concrements.
