Drip infusion pyelographyによる遊走腎の研究

Abstract

Drip infusion pyelography was carried out in 29 cases of nephroptosis detected by regular IVP. In all of 29 cases, nephrograms were more distinct than in IVP, therefore the size of the kidney was well delineated and changes at ptotic state were demonstrated more clearly. The most distinct nephrograms were obtained at 30 minutes films. So, these films were applied for comparison of nephrographic density of both kidneys as to intratubular urinary stasis. Ptotic kidney was denser than the contralateral kidney in 9, and in the rest both were almost same. From these findings, it was concluded that urinary stasis can be judged not only by pyelogram but by nephrogram, and that DIP is a useful way of demonstration of urinary stasis because of its diuretic action.
