[Analysis of site differences in voiding condition of elderly men-- comparison to results of mass screening for prostate diseases between the villages of Shimamaki-mura, Hokkaido and Satomi-Mura, Ibaraki].
We performed mass screening for prostate diseases in the village of Satomi-mura, in Ibaraki Prefecture for males between 40 and 79 years old (participation rate; 21%). The findings were compared to those obtained by mass screening in the village of Shimamaki-mura, in Hokkaido Prefecture, conducted by the same examiners in a consistent manner (participation rate; 47%). When we considered the difference in biopsy rates between the two sites, the detection rate of prostate cancer in Satomi-mura was similar to that in Shimamaki-mura. There were no apparent differences in distribution of prostate volume, the International Prostate Symptom Score (I-PSS) and maximum flow rate between the two sites for each 10-year-age group. Our findings suggested that there was little site difference in the detection rate of prostate cancer and voiding condition between the two villages.
