Criteria for examination of the urethra during excretory urography

Of 2,234 patients, 97 (4.3%) had symptoms suggesting of urethral diseases, and underwent excretory voiding urethrography (EVU) as part of their excretory urographic examination. Successful EVU examinations were obtained in 84 (87%); 43 (51%) had abnormal findings; 29 (34%) were normal; and 12 (12%) were considered probably normal, with no further study required. The additional portion of the study can be accomplished without a significant increase in examination time and without excessive additional imaging; it avoids the risks of catheterization.
