FIGURE 1 . (A and B) Delayed films of left collecting system demonstrating partially duplicated system with blind-ending ureteral stump off lower pole segment .
These are the selected delayed films from the intravenous pyelogram of a twenty-seven-yearold black man . His chief complaint was left renal colic which proved to be due to a distal left ureteral calculus . These radiographs bear visual testimony to the innumerable number of
upper tract anomalies which can be had with the often errant, if not determined ureteral bud . David Jay Cam, M . D. The Medical and Surgical Clinic, S.C . 100 N . E . Randolph Avenue Peoria, Illinois 61606
NOTE - Urograms of interest to our readers are welcome from urologists and radiologists . Contributions, including an abbreviated history and legend for the films, are to be sent to Arthur N . Tessler, M .D., feature editor.
