ESWL後にツムラ猪苓湯を投与し,排石促進効果の有無を検討した. 1)猪苓湯投与群と非投与群との間に年齢,性別,結石の大きさ及び結石部位の差はなかった. 2)ESWL後,完全排石までの平均日数は猪苓湯投与群で16.0±2.2日,非投与群で21.5±2.5日と,猪苓湯群の方が短い傾向を認め,20mm以下の結石では有意に排石までの期間が短かった.猪苓湯には排石促進作用があると考えたTo enhance stone elimination following extracorporeal shock wave lithotripsy (ESWL), we administered Tsumura Chorei-to to 74 patients who underwent the procedure at Kinki University School of Medicine and Kanbara Hospital between July 1990 and March 1991. We established a control group of 75 patients without medication. There was no significant difference between the two groups in terms of gender, age, stone size (mostly less than 20 mm), and stone position. The mean number of days required for complete stone elimination was 16.0 days in the Chorei-to administration group being significantly shorter than the 21.5 days in the control group (p < 0.001). These findings suggested that Chorei-to effectively enhanced the spontaneous discharge of fragmented stones following ESWL.
