About the so-called "pyelo-venösen Refluxes". O. Homuth (Zentralbl. F. Chir. 1929, No. 30)

O. Homuth (Zentralbl. F. Chir. 1929, No. 30), on the basis of experimental studies, came to the conclusion that, under physiological conditions, the contrast fluid passes into the tubular system of the kidney during lege artis performed by pyelography due to the diffusion of fluid with tissue fluid through the epithelium of the renal pelvis.
