尿管結石の自然排出について -とくにツムラ猪苓湯の影響についての検討-

Abstract

The effects of Tsumura Choreito, a Kanpo-prescription, on spontaneous passage of ureteral calculi were studied. Tsumura Choreito is granules of crude extraction from Chorei, Takusha, Bukuryo, Akyo and Kasseki. Effectiveness of this prescription of Kanpo on urolithiasis was reported in the past but we have found no statistical studies with regard to effects of Choreito on spontaneous passage of ureteral calculi. In this study, Tsumura Choreito, 2.5 g twice a day, was administered to 60 patients with ureteral stonc. 44 cases (73%) had spontaneous passage of calculi, and especially about 97% of patients with small stone (less than 65.5 mm3) experienced stone discharges spontaneously. The effects of some drugs upon the passage of calculi, which were reported by other authors and us, were compared with those of Tsumura Choreito. It was found that the effects of this prescription on the calculi passage were comparable with those described elsewhere on other drugs (Urocalun, Cospanon, Coliopan, Supanate and Sesden) and better than those of Isosorbide. In spite of the longterm administration of this drug, no noticeable side effects were observed.
