Radiopyelography, a new method for observing function of the renal pelvis has been documented in this communication with brief explanation of its basic concepts and procedure, Its graphic recording, radiopyelogram, showed a constant curve which could be expressed in a given formula. In addition it is valuable means for analysing a radiorenogram.
This study was undertaken to introduce electroureterography into the clinical field of urology, producing many types of electrodes cystoscopically applicable to the human ureter and modifying recording procedure. A success is reported here in graphic recording of the human ureter in a constant wave pattern using a “u-looped” electrode with some resulting data.
A case of unilateral renal papillary necrosis with many small calyceal stones in a 27-year-old woman is presented. A diagnosis was made already preoperatively by pyelography and urography and the kidney was surgically removed. The literature was reviewed especially on the stone-formation and on the roentgen findings.
