title: Prostatic calculi.
abstract: The presence of calculi in 300 whole prostates from consecutive autopsies were investigated by the Faxitron imaging technique. Calculi were found in 99% of the prostates, their number and size increasing with age. They were mainly localized in the ducts in the borderzone between the middle lobes and the periferal prostate posterolaterally, but often some were also found anteriorly in the centreline. Calculi were never seen in the middle lobes. We found no statistically significant relation between the number, size or localization of calculi and other morphological or pathological parameters. Prostatic calculi seem to be a part of the normal process of aging, and do in only exceedingly rare cases assume any clinical importance.
