We aimed to demonstrate the physical and chemical properties of prostate stones. We also aimed to determine possible relationship between inflammation of prostate gland and prostate stones. Methods: The consecutive patients (excluding subjects with PSA<4 ng/ml and urolithiasis), who underwent TURP operation and who were observed to have prostatic calculi duriñóng TURP, were included in the study. The prostatic stones obtained from each patient duriñóng TURP were analysed for chemical composition and observed under electron microscopy (SEM) for structure and surface morphology. The pathological specimens were assessed by the uropathologist for the final diagnosis and existence and degree of inflammation. Results: Five patients were included in the study. From each patient at least three (range 38) samples of stones (diameter varying from 1 mm up to 5 mm) were obtained. The stones were made of mixed composition of calcium phosphate and calcium carbonate. The stones were found to have lobular surface made up of small spheres under SEM. Histopathological examination of the TURP specimens revealed being prostatic hyperplasia accompanied with inflammation of mild to severe degree. Conclusions: Prostatic stones are concentrically precipitated calcium stones within the prostatic ductuli with granular grape like morphology. Histopathological inflammation seems to be associated with these prostatic calculi. © 2010 AEU. Published by Elsevier España, S.L.
