[Stones of the seminal vesicles and ejaculatory duct in infant: report of a case].
A 7-year-old boy was brought to our clinic with the chief complaint of terminal pain on urination. Rectal examination revealed a prostate of almost normal size and consistency, but seminal vesicles were palpated to be hard and in a painful mass. Plain x-ray and urethrogram demonstrated several small stones in the posterior urethra and in seminal vesicles. In the first operation, the stones located in the posterior urethra were removed through the transvesical approach, and the seminal vesicular stones were extirpated in the next operation. The stones were found to consist of magnesium ammonium phosphate by infrared rays spectrum analysis. The histopathological findings of the partially resected seminal vesicles showed no inflammatory or tuberculous changes. Twenty cases of stones in seminal vesicle, in seminal canal, or in ejaculatory duct have been reported in the Japanese literature. Etiology, pathology, clinical problems and therapy of the stones of seminal tract are discussed in relation to the cases reported in Japan including the present case.
