Ewha Womans University Hospital during the period from January 1981 to December 1990. The following results were obtained; 1) There were 36 cases(52.2%) of male and 33 cases(47.8%) of female and the major range of age distribution was between 30 decade to 50 decade, 45 cases(65.2%). 2) The level of obstruction was the upper ureter in 37 cases(51.4%), the mid in 2 cases(4.2%) and the lower in 32 cases(44.4%).
