ESWL, endourologyおよびdissolution併用によるサンゴ状シスチン結石の治療経験

Abstract

Two cases of complete staghorn calculi composed of cystine that were treated with ESWL, endourology and dissolution are reported. After successful dissolution in vitro using tromethamine (pH 8-10), the same solution was used to irrigate the renal collecting system via nephrostomy tube for residual fragments after ESWL and/or endourology. One patient was treated with dissolution for 60 days, the other patient for 6 days. After this therapy, these patients became almost stone-free. Our experience demonstrates that the residual fragments after ESWL and/or endourology with staghorn calculi composed of cystine can be dissolved by tromethamine.
