Mrs. W. B., aged 71, was extremely weak and decrepit, and it was highly desirable to make a definite diagnosis of the renal condition. At cystoscopy, January 19, on the left, the catheter passed readily, but on the right side it was obstructed within an inch of the lower orifice. Several different sizes and kinds of catheter were used successively, but nothing could be made to go farther than the one inch. Holding this in place as best we could, 12 per cent sodium iodide solution was injected and a roentgenogram taken which gave us a clue at least to the situation, as shown in figure 1. The kidney
