Uninfected prostatic calculi cause no symptoms, however, when infected, it serves as a source of resistance against antibiotic therapy. We have performed transabdominal and transrectal prostatic ultrasonography in 64 cases of chronic bacterial prostatitis, and these patients were divided into two groups ; calculi group(42 cases) and non-calculi group(22 cases). All patients of non-calculi group and 37 cases of calculi group were treated with oral antibiotics, and 5 cases of calculi group who had concomitant benign prostatic hyperplasia were treated with transurethral resection. The cure rate of antibiotic therapy in non-calculi group(63. %) was statistically higher than that in calculi group(3S.7%) (p=0.005). Five out of 17 cases in calculi group(42 cases) which had concomitant benign prostatic hyperplasia got transurethral resection and 4 of 5 cases became free from prostatitis after transurethral resection of prostate. Judging from the above results, the prostatic calculi can be easily detected by prostatic ultrasonography in patient with chronic bacterial prostatitis. By knowing the presence of prostatic calculi, the treatment modality can be chosen and the prognosis estimated. Furthermore, transurethral resection of prostate may be useful in the treatment of chronic bacterial prostatitis in old aged patients with benign prostatic hyperplasia.
