自家移植腎に対して経皮的腎砕石術を行つた1例

PERCUTANEOUS NEPHROLITHOTRIPSY IN A RENAL AUTOTRANSPLANTED PATIENT

　52歳男性，両側尿管狭窄のため，1979年右自家腎移植術を行つた。2年後に多発性脳梗塞となり，歩行不能となつた。両側腎結石，尿路感染症を頻発するため，1985年，まず左経皮的腎砕石術を施行，さらに自家移植腎に対して経皮的賢砕石術を施行した。結石成分は，リン酸マグネシウム・アンモニウムおよび蓚酸カルシウムであつた。術後経過は良好であつた。移植腎は皮膚に近く，経皮的操作は比較的容易であつた。

A 52-year-old man with a history of ureteral calculus and bilateral ureteral stricture had undergone a successful right renal autotransplantation. He had had multiple cerebral infarction two year later and was admitted because of recurrent urinary infection and calculous formation. Left renal calculi were removed percutaneously using formerly established nephrostomy track and renal calculi of autotransplanted kidney were managed by percutaneous nephrolithotripsy in two sessions successfuly. The procedure of percutaneous removal seemed to be easier in transplanted kidney than normally positioned kidney.
