点滴静注腎盂撮影法

Abstract

The drip infusion pyelography (DIP) was applied to t he roentgenological examination of the urinary tract. As a con t r ast medium, Conlaxin H 1 ml/kg diluted to 300 ml with Eurit or Conlaxin L 1 ml /kg diluted twice with Eurit was employed. The drip infusion was perfor m ed as fast as possible so as to be finished in about five minutes. No ureter pressing belt was used. The urogram obtained in this metho d was undoubtedly clearer than the standard excretory pyelogram, and besides presented more natural position and form of the ureter and the bladder in addition to satisfactory nephrogram and pyelogram. In the cases of stone-hydronephrosis exc r etion of DIP was better than that of the standard excretory pyelography. The cobra head phenomenon was frequently observed in stone in the lower ureter. The combination of tomography often so enhanced the diagnostic usefulness as to clearly delineate tuberculous cavern in the kidney, pyelogenic cyst and papillomatous tumor of the renal pelvis. As DIP is technically so simple and causes no serious side effect, its diagnostic usefulness may be highly estimated.
