Prostatography.

The direct intraprostatic injection of ethiodol was done in 10 cases to visualize the prostate gland. Immediately after the injection the contrast material was distributed uniformly throughout the prostatic lobe, opacifying it with a fine reticular pattern (prostatogram). The size, shape and intravesical projection of the prostate could be studied accurately in all patients and the findings were confirmed at operation. All patients tolerated the procedure well without any local or systemic complications. Direct intraprostatic injection of the contrast material did not alter the gross nor the microscopic anatomy of the gland. Prostatography is a safe adjuvant radiologic procedure to obtain a 3-dimensional image of prostatic hypertrophy. This information would be useful in the proper planning of operative or radiation treatment of prostatic diseases. It also might be helpful in delineating the deep-seated suspicious prostatic nodules that are inaccessible for clinical examination.
