Abstract:
This study was aimed to investigate the possible correlations between International Prostate Symptom Score (IPSS), volume of total and transition zone of prostate, and serum prostate specific antigen (PSA) level in 42 patients diagnosed and treated as benign prostatic hyperplasia. We got IPSS by interview and calculated the volume of the total and the transition zone (TZ vol) of prostate by transrectal ultrasonography. The size of the total prostate was 37.35+/-12.9 cc (mean+/-standard deviation) and that of the transition zone was 17.72 +/- 10.04 cc. Transition zone index(transition zone volume/total prostate volume, TZ index) was calculated and its value was 0.45 +/- 0.14. Symptom score was not correlated with total prostate volume, TZ volume or 72 index (r=0.27, p>0.05; r=0.23, p>0.05; r=0.16, p>0.05, respectively). Either it did not show correlation with serum PSA level (r=0.16, p>0.05). However, there were statistically significant correlations among serum PSA, total volume, TZ volume, TZ index (r=0.66, p<0.05; r=0.64, p<0.05; r=0.47, p<0.05). From these results, it is difficult to find significant correlations between symptom severity easured by IPSS and several clinical indices such as total prostate volume, transitional volume, TZ index or serum PSA level. Prospective study including developing a more objective symptom scoring system is needed to get a more useful clinical index reflecting the symptom severity of the BPH patients as well as clinical status of them.
